The HE4056 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.When the input supply (wall adapter or USB supply) is removed the HE4056 automatically enters a low current state dropping the battery drain current to less than2μ A.The HE4056 can be put into shutdown mode reducing the supply current to 55μA.Other features include Battery temperature monitor, under-voltage lockout, automatic recharge and two status pins to indicate charge and charge termination.1.1A Lithium Ion Battery Linear Charger Pin Configuration1.1A Lithium Ion Battery Linear ChargerAbsolute Maximum Ratings1.1A Lithium Ion Battery Linear ChargerCaution: The absolute maximum ratings are rated values exceeding which the product could suffer physical damage. These values must therefore not be exceeded under any conditions.1.1A Lithium Ion Battery Linear ChargerNote: The ●denotes specifications which apply over the full operating temperature rang, otherwise specifications are at TA=25℃，VCC=5V，unless otherwise specified.Description of the PrincipleThe HE4056 is a complete CC/CV linear charger for single cell lithium-ion batteries. CC/CV to charger batter by internal MOSFET .It can deliver up to 1.1A of charge current .No blocking diode or external current sense resistor is required. HE4056 include two Open-Drain charge status Pins: Charge status indicator CHRG and battery failure status output STDBY.The internal thermal regulation circuit reduces the programmed charge current if the die temperature attempts to rise1.1A Lithium Ion Battery Linear Chargerabove a preset value of approximately 145℃. This feature protects the HE4056 from excessive temperature, and allows the user to push the limits of the power handling capability of a given circuit board without risk of damaging the HE4056 or the external components. Another benefit of adopting thermal regulation is that charge current can be set according to typical, not worst-case, ambient temperatures for a given application with the assurance that the charger will automatically reduce the current in worst-case conditions.The charge cycle begins when the voltage at the VCC pin rises above the UVLO level, a current set resistor is connected from the PROG pin to ground, and the CE pin is pulled above the chip enable threshold.The CHRG pin outputs a logic low to indicate that the charge cycle is on going. At the beginning of the charge cycle, if the battery voltage is below 2.9V, the charge is in precharge mode to bring the cell voltage up to a safe level for charging. The charger goes into the fast charge CC mode once the voltage on the BAT pin rises above 2.9 V. In CC mode, the charge current is set by RPROG. When the battery approaches the regulation voltage 4.2V, the charge current begins to decrease as the HE4056 enters the CV mode. When the current drops to charge termination threshold, the charge cycle is terminated, and CHRG pin assumes a high impedance state to indicate that the charge cycle is terminated and STDBY pin is pulled low.The charge termination threshold is 10% of the current in CC mode. To restart the charge cycle, remove the input voltage and reapply it, or momentarily force CE pin to 0V. The charge cycle can also be automatically restarted if the BAT pin voltage falls below the recharge threshold. The on-chip reference voltage, error amplifier and the resistor divider provide regulation voltage with 1% accuracy which can meet the requirement of lithium-ion and lithium polymer batteries. When the input voltage is not present, or input voltage is below VBAT, the charger goes into a sleep mode, dropping battery drain current to less than 3μA. This greatly reduces the current drain on the battery and increases the standby time. The charger can be shutdown by forcing the CE pin to GND.The charging profile is shown in the following figure:1.1A Lithium Ion Battery Linear ChargerThe charge current is programmed using a single resistor from the PROG pin to ground. The program resistor and the charge current are calculated using the following equations.BATPROG I R 1450; In application, according the charge current to determine RPROG ,the relation between RPROG and charge current can reference the following chart:Charge TerminationA charge cycle is terminated when the charge current falls to 1/10th the programmed value after the final float voltage is reached. This condition is detected by using an internal filtered comparator to monitor the PROG pin. When the PROG pin voltage falls below 100mV for longer than tTEMP (typically 1.8mS), Charging is terminated. The charge current is latched off and the HE4056 enters standby mode, where the input supply current drops to 55μA ( Note:C/10 termination is disabled in trickle charging and thermal limiting modes).When charging, transient loads on the BAT pin can cause the PROG pin to fall below 100mV for short periods of timebefore the DC charge current has dropped to 1/10th the programmed value. The 1.8mS filter time (tTEMP) on the termination comparator ensures that transient loads of this nature do not result in premature charge cycle termination. Once the average charge current drops below 1/10th the programmed value, the HE4056 terminated the charge cycle and ceases to provide any current through the BAT pin. In this state all loads on the BAT pin must be supplied by the battery. The HE4056 constantly monitors the BAT pin voltage in standby mode. If this voltage drops below the 4.10V recharge threshold (VRECHRG ),another charge cycle begins and current is once again supplied to the battery. To manually restart a charge cycle when in standby mode, the input voltage must be removed and reapplied or the charger must be shut down and restarted using the PROG pin. Figure 1 shows the state diagram of a typical charge cycle1.1A Lithium Ion Battery Linear ChargerThermal limiting1.1A Lithium Ion Battery Linear ChargerAn internal thermal feedback loop reduces the programmed charge current if the die temperature attempts to rise above a preset value of approximately 145℃ . The feature protects the HE4056 from excessive temperature and allows the user to push the limits of the power handling capability of a given circuit board without risk of damaging the HE4056. The charge current can be set according to typical (not worst-case) ambient temperature with the assurance that the charger will automatically reduce the current in worst-case conditions.To prevent the damage caused by the very high or very low temperature done to the battery pack, the HE4056 continuously senses battery pack temperature by measuring the voltage at TEMP pin determined by the voltage divider circuit and the battery ’s internal NTC thermistor as shown in Figure 1.The HE4056 compares the voltage at TEMP pin (VTEMP) against its internal VLOW and VHIGH thresholds to determine if charging is allowed. In HE4056, VLOW is fixed at (45%×Vcc), while VHIGH is fixed at (80%×Vcc). If VTEMP<VLOW or VTEMP>VHIGH , it indicates that the battery temperature is too high or too low and the charge cycle is suspended. When VTEMP is between VLOW and VHIGH , charge cycle resumes. The battery temperature sense function can be disabled by connecting TEMP pin to GND.Under Voltage lockout (UVLO)An internal under voltage lockout circuit monitors the input voltage and keeps the charger in shutdown mode until VCC rises above the under voltage lockout threshold . If the UVLO comparator is tripped, the charger will not come out of shutdown mode until VCC rises 140mV above the battery voltage.Auto restartOnce charge is been terminated, HE4056 immediately use a 1.8ms filter time （ tRECHARGE ）on the termination comparator to constant monitor the voltage on BAT pin. If this voltage drops below the 4.1V recharge threshold (about between 80% and 90% of VCC), another charge cycle begins. This ensured the battery maintained (or approach) to a charge full status andavoid the requirement of restarting the periodic charging cycle. In the recharge cycle, CHRG pin enters a pulled down status.Stability ConsiderationsIn CC mode, the PROG pin is in the feedback loop, not the battery. The CC mode stability is affected by the impedance at the PROG pin. With no additional capacitance on the PROG pin, the charger is stable with program resistor values as high as 20K. However, additional capacitance on this node reduces the maximum allowed program resistor. Therefore, if IPROG pin is loaded with a capacitance C, the following equation should be used to calculate the maximum resistance value for RPROG ： PROGPROGC R ⨯⨯≤51021πAs user, may think charge current is important, not instantaneous current. For example, to run a low current mode switch power which parallel connected with battery, the average current from BAT pin usually importance to instantaneous current. In this case, In order to measure average charge current or isolate capacitive load from IPROG pin, a simple RC filter can be used on PROG pin as shown in Figure 2. In order to ensure the stability add a 10K resistor between PROG pin and filter capacitor.1.1A Lithium Ion Battery Linear ChargerFig.2 Isolating with capacitive load on PROG PinPower DissipationThe conditions that cause the HE4056 to reduce charge current through thermal feedback can be approximated by considering the power dissipated in the IC. Nearly all of this power dissipation is generated by the internal MOSFET-this is calculated to be approximately:BAT BAT CC D I V V P ⨯-=)(The approximate ambient temperature at which the thermal feedback begins to protect the ICis:JA D A P C T θ⨯-︒=145;So:JABAT BAT CC A I V V C T θ⨯⨯--︒=)(145For example: The HE4056 with 5V supply voltage through programmable provides full limiting current 850mA to a charge lithium-ion battery with 3.85V voltage.

In a fixed ambient temperature, the charge current is calculated to be approximately :JABAT CC ABAT）V （V T C I θ⨯--=︒145Just as Description of the Principle part talks about so, the current on PROG pin will reduce in proportion to the reduced charge current through thermal feedback. In HE4056 design applications don ’t need to considerate the worst case of thermal condition, this point is importance, because if the junction temperature up to 145℃ ,HE4056 will auto reduce the power dissipation.Thermal ConsiderationsBecause of the small size of the thin SOP-8 or ESOP-8 package, it is important to use a good thermal PC board layout to maximize the available charge current. The PC board copper is the heat sink. The footprint copper pads should be as wide as possible and expand out to larger copper areas to spread and dissipate the heat to the surrounding ambient. Other heat sources on the board, not related to the charger, must also be considered when designing a PC board layout because they will affect overall temperature rise and the maximum charge current.VCC bypass capacitorMany types of capacitors can be used for input bypassing, however, caution must be exercised when using multilayer ceramic capacitors. Because of the self-resonant and high Q characteristics of some types of ceramic capacitors, high voltage transients can be generated under some start-up conditions, such as connecting the charger input to a live powerHE40561.1A Lithium Ion Battery Linear Chargersource. Adding a 1.5Ω resistor in series with a ceramic capacitor will minimize start-up voltage transients.Charging Current Soft StartHE4056 includes a soft start circuit which used to maximize to reduce the surge current in the begging of charge cycle. When restart a new charge cycle, the charging current ramps up from 0 to the full charging current within 20μs. In the start process it can maximize to reduce the action which caused by surge current load.Board Layout ConsiderationsRPROG at PROG pin should be as close to HE4056 as possible, also the parasitic capacitance at PROG pin should be kept as small as possible.The capacitance at VCC pin and BAT pin should be as close to HE4056 as possible.During charging, HE4056’s temperature may be high, the NTC thermistor should be placed far enough to HE4056 so that the thermistor can reflect the battery ’s temperature correctly.It is very important to use a good thermal PC board layout to maximize charging current. The thermal path for the heat generated by the IC is from the die to the copper lead frame through the package lead (especially the ground lead) to the PC board copper, the PC board copper is the heat sink. The footprint copper pads should be as wide as possible and expand out to larger copper areas to spread and dissipate the heat to the surrounding ambient. Feed through vias to inner or backside copper layers are also useful in improving the overall thermal performance of the charger. Other heat sources on the board, not related to the charger, must also be considered when designing a PC board layout because they will affect overall temperature rise and the maximum charge current.The ability to deliver maximum charge current under all conditions require that the exposed metal pad on the back side of the HE4056 package be soldered to the PC board ground. Failure to make the thermal contact between the exposed pad on the backside of the package and the copper board will result in larger thermal resistance.Add thermal regulation currentIt will effective to decrease the power dissipation through reduce the voltage of both ends of the inner MOSFET. In the thermal regulation, this action of transporting current to battery will raise. One of the measure is through an external component(as a resistor or diode) to consume some power dissipation.For example: The HE4056 with 5V supply voltage through programmable provides full limiting current 1000mA to a charge lithium-ion battery with 3.8V voltage. If JA is 120℃/W, so that at 25℃ ambient temperature, the charge current is calculated to be approximately :JABAT CC BAT CC BAT）V R I V CC I θ⨯-⨯--=︒︒(25145In order to increase the thermal regulation charge current, can decrease the power dissipation of the IC through reducing the voltage (as show fig.3) of both two ends of the resistor which connecting in series with a 5V AC adapter.With square equation to calculate I BAT ：CCJAA CC BAT CC BAT CC BAT R T C R V V V V I 2)145(4)(2θ-︒⨯----=If RCC=0.25Ω, VCC=5V, VBAT=3.75V, TA=25℃ and JA =120℃/W, we can calculate the thermal regulation charge current: IBAT ＝1080mA. It means that in this structure it can output 1000mA full limiting charge current at more high ambient temperature environment.Although it can transport more energy and reduce the charge time in this application, but actually spread charge time, if1.1A Lithium Ion Battery Linear ChargerHE4056 stay in under-voltage state, when VCC becomes too low in voltage mode. Fig.4 shows how the voltage reduced with increase RCC value in this circuit. This technique will act the best function when in order to maintain the minimize thedimension of the components and avoid voltage decreased to minimize RCC .USB and Wall Adapter PowerHE4056 allows charging from a USB port, a wall adapter can also be used to charge Li-Ion/Li-polymer batteries. Figure 5 shows an example of how to combine wall adapter and USB power inputs. A P-channel MOSFET, Q1, is used to prevent back conducting into the USB port when a wall adapter is present and Schottky diode, D1, is used to prevent USB power loss through the 1K Ω pull-down resistor.Generally, AC adaptor is able to provide bigger much current than the value of specific current limiting which is 500mA for USB port. So can rise charge current to 600mA with using a N-MOSFET (Q1) and an additional set resistor value as highas 10K.HE40561.1A Lithium Ion Battery Linear ChargerHE4056 has two open-drain status indicator output CHRG and STDBY .CHRG is pull-down when the HE4056 in a charge cycle. In other status CHRG in high impedance,CHRG and are all in high impedance when the battery out of the normal temperature.Represent in failure state, when TEMP pin in typical connecting, or the charger with no battery: red LED and green LED all don ’t light. The battery temperature sense function is disabled by connecting TEMP pin to GND. If battery is not connected to charger,CHRG pin outputs a PWM level to indicate no battery. If BAT pin connects a 10μF capacitor, the frequency of CHRG flicker about 1-4S, If not use status indicator should set status indicator output connected to GND.The values of R1 and R2 in the application circuit can be determined according to the assumed temperature monitor range and thermistor ’s values. The Follows is an example: Assume temperature monitor range is TL ～TH ，(TL ＜TH)；the thermistor in battery has negative temperature coefficient （NTC ），RTL is thermistor ’s resistance at TL ， RTH is the resistance atTH ，so RTL ＞RTH ，then at temperature TL, the voltage at TEMP pin is:INTHTHTEMPH V R R R R R V ⨯+=////212At temperature TH, the voltage at TEMP pin is:INTLTLTEMPL V R R R R R V ⨯+=////212We know VTEMPL ＝VHIGH ＝K2×Vcc (K2=0.8)；VTEMPH ＝VLOW ＝K1×Vcc (K1=0.45) Then we can have ：12121)()(K K R R K K R R R TH TL TH TL ⨯--⨯=;)()()(212211121K K K R K K K R K K R R R TH TL TH TL ⨯--⨯--⨯=Likewise, for positive temperature coefficient thermistor in battery, we have RTH ＞RTL and we can calculate:12121)()(K K R R K K R R R TL TH TH TL ⨯--⨯=;)()()(212211121K K K R K K K R K K R R R TL TH TH TL ⨯--⨯--⨯=We can conclude that temperature monitor range is independent of power supply voltage VCC and it only depends on R1, R2, RTL and RTH: The values of RTH and RTL can be found in related battery handbook or deduced from testing data. In actual application, if only one terminal temperature is concerned (normally protecting overheating), there is no need to use R2 but R1. It becomes very simple to calculate R1 in this case.Block Diagram1.1A Lithium Ion Battery Linear Charger1.1A Lithium Ion Battery Linear ChargerC210uF1.1A Lithium Ion Battery Linear ChargerPackaging Information:SOP8 PACKAGE OUTLINE DIMENSIONS。

8-channel analog multiplexer/demultiplexer
Rev. 04 — 12 January 2005 Product data sheet
1. General description
The HEF4051B is an 8-channel analog multiplexer/demultiplexer with three address inputs (A0 to A2), an active LOW enable input (E), eight independent inputs/outputs (Y0 to Y7) and a common input/output (Z). The device contains eight bidirectional analog switches, each with one side connected to an independent input/output (Y0 to Y7) and the other side connected to a common input/output (Z). With E LOW, one of the eight switches is selected (low-impedance ON-state) by A0 to A2. With E HIGH, all switches are in the high-impedance OFF-state, independent of A0 to A2. If break before make is needed, then it is necessary to use the enable input. VDD and VSS are the supply voltage connections for the digital control inputs (A0 to A2, and E). The VDD to VSS range is 3 V to 15 V. The analog inputs/outputs (Y0 to Y7, and Z) can swing between VDD as a positive limit and VEE as a negative limit. VDD − VEE may not exceed 15 V. For operation as a digital multiplexer/demultiplexer, VEE is connected to VSS (typically ground).

The HE4054 automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.When the input supply (wall adapter or USB supply) is removed the HE4054 automatically enters a low current state dropping the battery drain current to less than 2μA.The HE4054 can be put into shut down mode reducing the supply current to 55μA.Other features include Battery temperature monitor, under-voltage lockout, automatic recharge and two status pins to indicate charge and charge termination.Li-lon battery charger Pin ConfigurationPin AssignmentAbsolute Maximum Ratingssuffer physical damage. These values must therefore not be exceeded under any conditions.Li-lon battery chargerElectrical Characteristics(VIN = 5V; TJ = 25°C; unless otherwise specified.)Li-lon battery chargerDescription of the PrincipleThe HE4054 is a complete CC/CV linear charger for single cell lithium-ion batteries. CC/CV to charger batter by internal MOSFET .It can deliver up to 800mA of charge current .No blocking diode or external current sense resistor is required.HE4054 include Open-Drain charge status Pins: Charge status indicator CHRG.The internal thermal regulation circuit reduces the programmed charge current if the die temperature attempts to rise above a preset value of approximately 145℃. This feature protects theHE4054 from excessive temperature, and allows the user to push the limits of the power handling capability of a given circuit board without risk of damaging theHE4054 or the external components. Another benefit of adopting thermal regulation is that charge current can be set according to typical, not worst-case, ambient temperatures for a given application with the assurance that the charger will automatically reduce the current in worst-case conditions.The charge cycle begins when the voltage at the V CC pin rises above the UVLO level, a current set resistor is connected from the PROG pin to ground, The CHRG pin outputs a logic low to indicate that the charge cycle is on going. At the beginning of the charge cycle, if the battery voltage is below 2.9V, the charge is in precharge mode to bring the cell voltage up to a safe level for charging. The charger goes into the fast charge CC mode once the voltage on the BAT pin rises above 2.9 V. In CC mode, the charge current is set by R PROG. When the battery approaches the regulation voltage 4.2V, the charge current begins to decrease as theHE4054 enters the CV mode. When the current drops to charge termination threshold, the charge cycle is terminated, and CHRG pin assumes a high impedance state to indicate that the charge cycle is terminated.The charge termination threshold is 10% of the current in CC mode. The charge cycle can also be automatically restarted if the BAT pin voltage falls below the recharge threshold. The on-chip reference voltage, error amplifier and the resistor divider provide regulation voltage with 1% accuracy which can meet the requirement of lithium-ion and lithium polymer batteries. When the input voltage is not present, or input voltage is below V BAT, the charger goes into a sleep mode, dropping battery drain current to less than 3μA. This greatly reduces the current drain on the battery and increases the standby time. The charging profile is shown in the following figure:Li-lon battery chargerProgramming Charge CurrentThe charge current is programmed using a single resistor from the PROG pin to ground. The program resistor and the charge current are calculated using the following equations.BAT PROG I R 1450;In application, according the charge current to determine R PROG ,the relation between R PROG and chargeCharge TerminationA charge cycle is terminated when the charge current falls to 1/10th the programmed value after the final float voltage is reached. This condition is detected by using an internal filtered comparator to monitor the PROG pin. When the PROG pin voltage falls below 100mV for longer than t TEMP (typically 1.8mS), Charging is terminated. The charge current is latched off and theHE4054 enters standby mode, where the input supply current drops to 55μA ( Note:C/10 termination is disabled in trickle charging and thermallimiting modes).When charging, transient loads on the BAT pin can cause the PROG pin to fall below 100mV for short periods of time before the DC charge current has dropped to 1/10th the programmed value. The 1.8mS filter time (t TEMP ) on the termination comparator ensures that transient loads of this nature do not result in premature charge cycle termination. Once the average charge current drops below 1/10th the programmed value, theHE4054 terminated the charge cycle and ceases to provide any current through the BAT pin. In this state all loads on the BAT pin must be supplied by the battery.TheHE4054 constantly monitors the BAT pin voltage in standby mode. If this voltage drops below theLi-lon battery charger4.10V recharge threshold (V RECHRG ),another charge cycle begins and current is once again supplied to the battery. To manually restart a charge cycle when in standby mode, the input voltage must be removed and reapplied or the charger must be shut down and restarted using the PROG pin. Figure 1 shows the state diagram of a typical charge cycleFig.1 State diagram of a typical charge cycleThermal limitingLi-lon battery chargerAn internal thermal feedback loop reduces the programmed charge current if the die temperature attempts to rise above a preset value of approximately 145℃ . The feature protects theHE4054 from excessive temperature and allows the user to push the limits of the power handling capability of a given circuit board without risk of damaging theHE4054. The charge current can be set according to typical (not worst-case) ambient temperature with the assurance that the charger will automatically reduce the current in worst-case conditions.Under Voltage lockout (UVLO)An internal under voltage lockout circuit monitors the input voltage and keeps the charger in shutdown mode until V CC rises above the under voltage lockout threshold . If the UVLO comparator is tripped, the charger will not come out of shutdown mode until V CC rises 140mV above the battery voltage.Auto restartOnce charge is been terminated,HE4054 immediately use a 1.8ms filter time （ t RECHARGE ）on the termination comparator to constant monitor the voltage on BAT pin. If this voltage drops below the 4.1V recharge threshold (about between 80% and 90% of V CC ), another charge cycle begins. This ensured the battery maintained (or approach) to a charge full status and avoid the requirement of restarting the periodic charging cycle. In the recharge cycle, CHRG pin enters a pulled down status.Stability ConsiderationsIn CC mode, the PROG pin is in the feedback loop, not the battery. The CC mode stability is affected by the impedance at the PROG pin. With no additional capacitance on the PROG pin, the charger is stable with program resistor values as high as 20K. However, additional capacitance on this node reduces the maximum allowed program resistor. Therefore, if I PROG pin is loaded with a capacitance C, the following equation should be used to calculate the maximum resistance value for R PROG ：PROGPROG C R ⨯⨯≤51021π As user, may think charge current is important, not instantaneous current. For example, to run a low current mode switch power which parallel connected with battery, the average current from BAT pin usually importance to instantaneous current. In this case, In order to measure average charge current or isolate capacitive load from I PROG pin, a simple RC filter can be used on PROG pin as shown in Figure 2. In order to ensure the stability add a 10K resistor between PROG pin and filter capacitor.Li-lon battery chargerFig.2 Isolating with capacitive load on PROG PinPower DissipationThe conditions that cause theHE4054 to reduce charge current through thermal feedback can be approximated by considering the power dissipated in the IC. Nearly all of this power dissipation is generated by the internal MOSFET-this is calculated to be approximately:BAT BAT CC D I V V P ⨯-=)(The approximate ambient temperature at which the thermal feedback begins toprotect the IC is:JA D A P C T θ⨯-︒=145; So: JA BAT BAT CC A I V V C T θ⨯⨯--︒=)(145For example: TheHE4054 with 5V supply voltage through programmable provides full limiting current 550mA to a charge lithium-ion battery with 3.85V voltage. If JA is 120℃/W ( reference to PCB layout considerations), WhenHE4054 begins to decrease the charge current, the ambient temperature about:C T A ︒=⨯⨯--=1.6912055.0)85.35(145HE4054 can work in the condition of the temperature is above 69.1℃, but the charge current will pull down to below 550mA. In a fixed ambient temperature, the charge current is calculated to be approximately :JABAT CC ABAT）V （V T C I θ⨯--=︒145 Just as Description of the Principle part talks about so, the current on PROG pin will reduce in proportion to the reduced charge current through thermal feedback. In HE4054 design applications don ’t need to considerate the worst case of thermal condition, this point is importance, because if the junction temperature up to 145℃ ,HE4054 will auto reduce the power dissipation.Thermal ConsiderationsBecause of the small size of the thin SOT23-5 package, it is important to use a good thermal PC board layout to maximize the available charge current. The PC board copper is the heat sink. The footprintHE4054Li-lon battery chargercopper pads should be as wide as possible and expand out to larger copper areas to spread and dissipate the heat to the surrounding ambient. Other heat sources on theboard, not related to the charger, must also be considered when designing a PC board layout because they will affect overall temperature rise and the maximum charge current.VCC bypass capacitorMany types of capacitors can be used for input bypassing, however, caution must be exercised when using multilayer ceramic capacitors. Because of the self-resonant and high Q characteristics of some types of ceramic capacitors, high voltage transients can be generated under some start-up conditions, such as connecting the charger input to a live power source. Adding a 1.5Ωresistor in series with a ceramic capacitor will minimize start-up voltage transients.Charging Current Soft StartHE4054 includes a soft start circuit which used to maximize to reduce the surge current in the begging of charge cycle. When restart a new charge cycle, the charging current ramps up from 0 to the full charging current within 20μs. In the start process it can maximize to reduce the action which caused by surge current load.Board Layout ConsiderationsR PROG at PROG pin should be as close toHE4054 as possible, also the parasitic capacitance at PROG pin should be kept as small as possible.The capacitance at VCC pin and BAT pin should be as close toHE4054 as possible.It is very important to use a good thermal PC board layout to maximize charging current. The thermal path for the heat generated by the IC is from the die to the copper lead frame through the package lead (especially the ground lead) to the PC board copper, the PC board copper is the heat sink. The footprint copper pads should be as wide as possible and expand out to larger copper areas to spread and dissipate the heat to the surrounding ambient. Feed through vias to inner or backside copper layers are also useful in improving the overall thermal performance of the charger. Other heat sources on the board, not related to the charger, must also be considered when designing a PC board layout because they will affect overall temperature rise and the maximum charge current.The ability to deliver maximum charge current under all conditions require that the exposed metal pad on the back side of theHE4054 package be soldered to the PC board ground. Failure to make the thermal contact between the exposed pad on the backside of the package and the copper board will result in larger thermal resistance.Typical ApplicationHE4054Li-lon battery charger H E4054HE4054Li-lon battery chargerVer0.1 11 Jul 26,2013Package Information5-pin SOT23-5L Outline Dimensions。

概述
HE4057是一款性能优异的单节锂离子电池恒流/恒压线性充电器。
HE4057采用SOT23-6封装配合较少的外围原件使其非常适用于便携式产品，并且适合给USB电源以及适配器电源供电。
基于特殊的内部MOSFET架构以及防倒充电路，HE4057不需要外接检测电阻和隔离二极管。
当外部环境温度过高或者在大功率应用时，热反馈可以调节充电电流以降低芯片温度。
充电电压固定在4.2V，而充电电流则可以通过一个电阻器进行外部设置。
当充电电流在达到最终浮充电压之后降至设定值的1/10，芯片将终止充电循环。
当输入电压断开时，HE4057进入睡眠状态，电池漏电流将降到1uA以下。
HE4057可以被设置于停机模式，此时芯片静态电流降至25uA。
HE4057还包括其他特性：电池温度监测，欠压锁定，自动再充电和两个状态引脚以显示充电和充电终止。

使用说明
HE4057是一款专门为锂离子电池设计的线性充电器，利用芯片内部的功率MOSFET对电池进行恒流/恒压充电。
充电电流可以由外部电阻编程决定，最大充电电流可以达到500mA。
HE4057拥有两个漏极开路输出的状态指示输出端，充电状态指示端CHRG和电池充电完成指示输出端STDBY。
芯片内部的功率管电路在芯片的结温超过135℃时自动降低充电电流，这个功能可以使用户最大限度利用芯片充电，不用担心芯片过热而损坏芯片或者外部元器件。
●工作原理
当输入电压大于UVLO检测阈值和芯片使能输入端接高电平时，HE4057开始对电池充电。
如果电池电压低于
2.9V，充电器用小电流对电池进行预充电。
当电池电压超过2.9V时，充电器采用恒流模式对电池充电，充电电流由PROG端和GND端之间的电阻决定。
当电池电压接近4.2V时，充电电流逐渐减小，HE4057进入恒压充电模式。
当充电
电流减小到充电结束阈值时，充电周期结束。
充电结束阈值是恒流充电电流的1/10。
当电池电压降到再充电阈值以下时，自动开始新的充电周期。
芯片内部的高精度的电压基准源，误差放大器和电阻分压网络确保BAT端调制电压的精度在1%以内，满足锂离子和锂聚合物电池的要求。
当输入电压掉电或者输入电压低于电池电压时，充电器进入待机模式，电池端消耗的电流小于2uA，从而增加待机时间。
●充电终止
当充电电流在达到最终浮充电压之后降至设定值的1/10，充电循环被终止。
该条件是通过采用一个内部滤波比较器对PROG端进行监控来检测的。
当PROG端电压降至100mV以下的时间超过1.8ms时，充电终止，HE4057进入待机模式，此时的输入电源电流降至约45uA。
充电时，BAT端上的瞬变负载会使PROG端电压在DC充电电流降至设定值的1/10之间短暂地降至100mV以下，比较器的1.8ms延时时间确保了这种性质的瞬变负载不会导致充电循环过早终止。
一旦平均充电电流降至设定值的1/10以下，HE4057集中式充电循环并停止通过BAT端提供任何电流。
在这种状态下，BAT端上所有负载都必须由电池供电。
●充电状态指示
HE4057有两个漏极开路状态指示输出端CHRG和STDBY。
当充电器处于充电状态时，CHRG被拉到低电平，在其他状态CHRG为高阻态；当电池充电结束后，STDBY被拉到低电平，在其他状态STDBY为高阻态。
当电池没有接到充电器时，CHRG闪烁表示没有安装电池。
●热限制
如果芯片温度升至135 C以上时，一个内部热反馈环路将减小设定的充电电流。
该功能可防止HE4057过热，并允许用户提高给定电路板功率处理能力的上限而减小损坏HE4057的风险。
●欠压锁闭
HE4057拥有一个内部欠压锁定电路对输入电压进行监控，在V CC升至欠压锁定门限电压之前使芯片保持在停机工作模式。
当V CC电压升高至3.8V之后，芯片退出UVLO，开始正常工作。
V CC下降时的UVLO迟滞电压为200mV。
●自动充电循环
电池电压达到浮充电压，充电循环被终止之后，HE4057立即对BAT端电压进行监控。
当BAT端电压低于4.1V时，
充电循环重新开始。
确保了电池被维持在一个接近满电的状态，同时免除了进行周期性充电循环启动的需要。
