The charge current is programmable to USB100, USB500 or ISET mode and the CV mode voltage is fixed at 4.2V. The pre-charge threshold is fixed at 2.5V. If the battery voltage is below the pre-charge threshold, the RT9524 charges the battery with a trickle current until the battery voltage rises above the pre-charge threshold. The RT9524 is capable of being powered up from AC adapter and USB (Universal Serial Bus) port inputs. Moreover, the RT9524 include a linear regulator (LDO 4.9V, 50mA) for supplying low power external circuitry.ACIN Over Voltage ProtectionThe input voltage is monitored by the internal comparator and the input over voltage protection threshold is set to 6.9V. However, input voltage over 28V will still cause damage to the RT9524. When the input voltage exceeds the threshold, the comparator outputs a logic signal to turn off the power P-MOSFET to prevent the high input voltage from damaging the electronics in the handheld system. When the input over voltage condition is removed, the comparator re-enables the output by running through the soft-start.Charger Enable and mode SettingEN/SET is used to enable or disable the charger as well as to select the charge current limit. Drive the EN pin to low or leave it floating to enable the charger. The EN/SET pin has a 200kΩ internal pull down resistor. So, when left floating, the input is equivalent to logic low. Drive this pin to high to disable the charger. After the EN/SET pin pulls low for 50μs, the RT9524 enters the USB500 mode and wait for the setting current signal. EN/SET can be used to program the charge current during this cycle. The RT9524 will change its charge current by sending different pulse to EN/SET pin. If no signal is sent to EN/SET, the RT9524 will remain in USB500 mode. A correct period of time for high pulse is between 100μs and 700μs and the period of pulse to pulse must be between 100μs and 700μs to be properly read. Once EN/SET is held low for 1.5ms,the number of pulses is locked and sent to the control logic and then the mode changes. The RT9524 needs to be restarted to reset the charge current. Once the EN/ SET input is held high for more than 1.5ms, the RT9524 is disabled.Table 1. Pulse Counting Map for EN/SET InterfaceFigure .1 (b)Battery Charge ProfileThe RT9524 charges a Li-Ion battery with a constant current (CC) or a constant voltage (CV).The constant current is decided by the operation mode of USB100, USB500 or ISET mode. The constant current is set with the external resistor R ISET and the constant voltage is fixed at 4.2V. If the battery voltage is below the Pre-Charge Threshold, the RT9524 charges the battery with a trickle current until the battery voltage rises above the trickle charge threshold. When the battery voltage reaches 4.2V, the charger enters CV mode and regulates the battery voltage at 4.2V to fully charge the battery without the risk of over chargingFigure .1 (a)IIDS9524-01 April 2011Battery Pre-Charge CurrentDuring a charge cycle, if the battery voltage is below the pre-charge threshold, the RT9524 enters the pre-charge mode. This feature revives deeply discharged cells and protects battery. Under USB100 Mode, the pre-charge current is internally set to 95mA. When the RT9524 is under USB500 and ISET Mode, the pre-charge current is 20% of fast-charge current set by external resistor R ISET .Battery Fast-Charge Current ISET ModeThe RT9524 offers ISET pin to program the charge current.The resistor R ISET is connected to ISET and GND. The parameter K ISET is specified in the specification table.ISEF Charge ISEF ISETKI = ; K = 530R USB500 and USB100 ModeThe fast-charge current is 95mA in USB100 mode and 395mA in USB500 mode. Note that if the fast-charge current set by external resistor is smaller than that in USB500 mode (395mA), the RT9524 charges the battery in ISET mode.Battery Voltage Regulation (CV Mode)The battery voltage regulation feedback is through the BATT pin. The RT9524 monitors the battery voltage between BATT and GND pins. When the battery voltage closes in on the battery regulation voltage threshold, the voltage regulation phase begins and the charging current begins to taper down. When the charging current falls below the programmed end-of-charge current threshold,the CHGSB pin goes high to indicate the termination of charge cycle.The end-of-charge current threshold is set by the IEOC pin. The resistor R EOC is connected to IEOC and GND.The parameters K EOC and IEOC are specified in the specification table.EOC EOC EOC EOC RI (%) = ; K = 200K The current threshold of IEOC (%) is defined as the percentage of fast-charge current set by R ISET . After the CHGSB pin is pulled high, the RT9524 still monitors the battery voltage. Charge current is resumed when the battery voltage goes to lower than the battery regulation voltage threshold.Factory ModeThe RT9524 provides factory mode for supplies up to 2.3A for powering external loads with no battery installed and BATT is regulated to 4.2V. The factory mode allows the user to supply system power with no battery connected.In factory mode, thermal regulation is disabled but thermal protection (155°C) is still active. When using currents greater than 1.5A in factory mode, the user must limit the duty cycle at the maximum current to 20% with a maximum period of 10ms.LDOThe RT9524 integrates one low dropout linear regulator(LDO) that supplies up to 50mA. The LDO is active whenever the input voltage is between POR threshold andFigure 2Figure 32004006008001000120014000.40.60.81 1.2 1.4 1.61.82 2.22.4 2.62.83R SET ∠)B a t t e r yC h a r g e C u r r e n t (m A )(k ΩOVP threshold. It is not affected by the EN/SET input.Note that the LDO current is independence and not monitored by the charge current limit.Charge Status Outputs (CHGSB and PGB)The open-drain CHGSB and PGB outputs indicate various charger operations as shown in the following table. These status pins can be used to drive LEDs or communicate to the host processor. Note that ON indicates the open-drain transistor is turned on and LED is bright.Table 2Sleep ModeThe RT9524 enters sleep mode if the power is removed from the input. This feature prevents draining the battery during the absence of input supply.Temperature Regulation and Thermal Protection In order to maximize charge rate, the RT9524 features a junction temperature regulation loop. If the power dissipation of the IC results in a junction temperature greater than the thermal regulation threshold (125°C), the RT9524 limits the charge current in order to maintain a junction temperature around the thermal regulation threshold (125°C). The RT9524 monitors the junctiontemperature, T J , of the die and disconnects the battery from the input if T J exceeds 125°C. This operation continues until junction temperature falls below thermal regulation threshold (125°C) by the hysteresis level. This feature prevents maximum power dissipation from exceeding typical design conditions.Selecting the Input and Output CapacitorsIn most applications, all that is needed is a high-frequency decoupling capacitor on the input. A 1μF ceramic capacitor,placed in close proximity to input to GND, works well. Insome applications depending on the power supplycharacteristics and cable length, it may be necessary toadd an additional 10μF ceramic capacitor to the input.The RT9524 requires a small output capacitor for loop stability. A typical 1μF ceramic capacitor placed between the BATT pin and GND is sufficient.Thermal ConsiderationsFor continuous operation, do not exceed absolutemaximum operation junction temperature. The maximum power dissipation depends on thermal resistance of the IC package, PCB layout, rate of surrounding airflow, and difference between junction and ambient temperature. Themaximum power dissipation can be calculated by thefollowing formula :P D(MAX) = (T J(MAX) − T A ) / θJAwhere T J(MAX) is the maximum operation junctiontemperature, T A is the ambient temperature, and θJA is thejunction to ambient thermal resistance.For recommended operating conditions specification of RT9524, the maximum junction temperature is 125°C and T A is the maximum ambient temperature. The junction to ambient thermal resistance, θJA , is layout dependent. For WDFN-10L 3x2 packages, the thermal resistance, θJA , is 90°C/W on a standard JEDEC 51-7 four-layer thermal test board. The maximum power dissipation at T A = 25°C can be calculated by the following formula :P D(MAX) = (125°C − 25°C) / (90°C/W) = 1.111W for WDFN-10L 3x2 packageThe maximum power dissipation depends on operating ambient temperature for fixed T J(MAX) and thermal resistance, θJA . For RT9524 package, the derating curveRT952411DS9524-01 April 2011in Figure 4 allows the designer to see the effect of rising ambient temperature on the maximum power dissipation.Figure 4. Derating Curve for RT9524 Package Layout ConsiderationThe RT9524 is a fully integrated low cost single-cell Li-Ion battery charger IC ideal for portable applications. Careful PCB layout is necessary. For best performance, place all peripheral components as close to the IC as possible. A short connection is highly recommended. The following guidelines should be strictly followed when designing a PCB layout for the RT9524.`Input capacitor should be placed close to the IC and connected to ground plane. The trace of input in the PCB should be placed far away from the sensitive devices or shielded by the ground.`The GND should be connected to a strong ground plane for heat sinking and noise protection.`The connection of R ISET and R IEOC should be isolated from other noisy traces. The short wire is recommended to prevent EMI and noise coupling.`Output capacitor should be placed close to the IC and connected to ground plane to reduce noise coupling.Figure 5.

______________________Description
The SLM6150 is a complete constant current & constant voltage linear charger for single cell lithium-ionbatteries. Its SOP package low external component count make the SLM6150 ideally suited for portable applications. The SLM6150 is specifically designed to work within USB supply and adapter specifications. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The SLM6150 automatically terminates the charge cycle when the charge current dropsto 1/10 of the programmed value after the final float voltage is reached. Whenthe input supply(Adapter or USB supply) is removed, the SLM6150 automatically enters a low current state, droppingthe battery draincurrent to less than 2uA. The SLM6150 can be put into shutdown mode even if the power supply connected, and the supplycurrent canbereducedto 55uA. Other features of SLM6150 include Battery temperature monitor, under-voltage lockout, automatic recharge and two status pins to indicate charge andcharge termination. __________ AbsollutteMaxiimum Ratiings � � � � � � Vcc:-0.3V~8V PROG:-0.3V~Vcc+0.3V BAT:-0.3V~7V CHRG:-0.3V~10V STDBY:-0.3V~10V TEMP:-0.3V~10V 1 / 12

MAX1551 MAX1555 单细胞锂离子电池充电器说明书
General DescriptionThe MAX1551/MAX1555 charge a single-cell lithium-ion (Li+) battery from both USB* and AC adapter sources.They operate with no external FETs or diodes, and accept operating input voltages up to 7V.On-chip thermal limiting simplifies PC board layout and allows optimum charging rate without the thermal limits imposed by worst-case battery and input voltage. When the MAX1551/MAX1555 thermal limits are reached, the chargers do not shut down, but progressively reduce charging current.The MAX1551 includes a POK output to indicate when input power is present. If either charging source is active, POK goes low. The MAX1555 instead features a CHG output to indicate charging status.With USB connected, but without DC power, charge cur-rent is set to 100mA (max). This allows charging from both powered and unpowered USB hubs with no port communication required. When DC power is connected,charging current is set at 280mA (typ). No input-blocking diodes are required to prevent battery drain.The MAX1551/MAX1555 are available in 5-pin thin SOT23packages and operate over a -40°C to +85°C range.ApplicationsPDAsWireless Appliances Cell Phones Digital CamerasFeatureso Charge from USB or AC Adaptero Automatic Switchover when AC Adapter is Plugged In o On-Chip Thermal Limiting Simplifies Board Design o Charge Status Indicator o 5-Pin Thin SOT23 Packageo Protected by U.S. Patent #6,507,172MAX1551/MAX1555SOT23 Dual-Input USB/AC Adapter 1-Cell Li+Battery Chargers________________________________________________________________Maxim Integrated Products1Ordering Information19-2902; Rev 0; 7/03For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Pin ConfigurationTypical Operating Circuit*Protected by U.S. Patent #6,507,172.Selector GuideM A X 1551/M A X 1555SOT23 Dual-Input USB/AC Adapter 1-Cell Li+Battery Chargers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

These devices operate with no external FETs or diodes, and accept operating input voltages up to 7V.An internal thermal control loop simplifies PC board lay-out and allows optimum charging rate without the ther-mal limits imposed by worst-case battery and input voltage. When the MAX1551/MAX1555 thermal limits are reached, the chargers do not shut down, but simply reduce charging current by 17mA/°C above a die tem-perature of +110°C.With USB connected, but without DC power, the charge current is set to 100mA (max). This allows charging from both powered and unpowered USB hubs with no port communication required. When DC power is con-nected, charging current is set at 280mA (typ). The MAX1551/MAX1555 do not feature an enable input.Once power is connected to USB and/or DC, the charger is on.When input power is removed, battery leakage current is less than 5µA. No input-blocking diodes are required to prevent battery drain. Insert a diode at DC (the adapter input) if protection from negative voltage inputs (reversed-polarity adapter plugs) is required.USB to Adapter Power HandoffThe MAX1551/MAX1555 can charge from either the USB input or the DC input. The battery does not charge from both sources at the same time. The MAX1551/MAX1555 automatically detect the active input and charge from that. If both power sources are active, the DC input takes precedence. The switchover between DC and USB is detailed in Table 1.MAX1551 Power-OK (POK )The MAX1551’s POK is an active-low, open-drain out-put that goes low when V DC or V USB is above 3.95V.POK can be used as a logic output or can drive an LED. POK indicates the charger is connected to input power and is charging.MAX1555 Charge Status (CHG )The MAX1555’s CHG is an active-low, open-drain charge status indicator. CHG pulls low when the battery is charging (whenever USB or DC are powered) and charge current is greater than 50mA. CHG indicates when the battery is fully charged by going high imped-ance when the charger is in voltage mode and charge current falls below 50mA. Charging does not stop when CHG goes high. CHG is low in precharge mode.MAX1551/MAX1555SOT23 Dual-Input USB/AC Adapter 1-Cell Li+Battery Chargers_______________________________________________________________________________________5Pin DescriptionTable 1. USB and DC Input SelectionM A X 1551/M A X 1555Precharge CurrentThe MAX1551/MAX1555 feature a precharge current to protect deeply discharged cells. If V BAT is less than 3V,the device enters precharge mode where charging cur-rent is limited to 40mA.Package Thermal LimitingOn-chip thermal limiting in the MAX1551/MAX1555 sim-plifies PC board layout and allows charging rates to be optimized without the limits imposed by worst-case bat-tery and input voltages. The device reduces the power dissipation at BAT to prevent overheating. This allows the board design to be optimized for compact size and typical thermal conditions. When the MAX1551/MAX1555 thermal limits are reached, the chargers donot shut down, but progressively reduce charging cur-rent by 17mA/°C above a die temperature of +110°C.Solder the MAX1551/MAX1555s ’ GND to a large ground plane to help dissipate power and keep the die temperature below the thermal limit. The USB charge current of 100mA is unlikely to induce thermal limiting.Bypass CapacitorsUse ceramic bypass capacitors at DC, USB, and BAT.Mount these capacitors within 1cm of their respective pins. X7R and X5R dielectrics are recommended.Chip InformationTRANSISTOR COUNT: 541PROCESS: BiCMOSSOT23 Dual-Input USB/AC Adapter 1-Cell Li+Battery Chargers 6_______________________________________________________________________________________Typical Application CircuitMAX1551/MAX1555SOT23 Dual-Input USB/AC Adapter 1-Cell Li+Battery ChargersPackage Information(The package drawing(s) in this data sheet may not reflect the most current specifications.

放电过流 2 阈值,一般为过流 1 与短路的缓冲,保证在没有发生短路电流的情况下,此时电流也较大,需要 能够较快关闭放电 MOS,阈值一般会根据所选择的放电 MOSFET 的过电流能力与实际过流 1 而定。
4)
有些应用情况下,启动电流会大于放电过流 1 阈值,启动时间要小于放电过流 1 延迟时间,保证用户能够正 常启动;当启动电流过大,导致启动瞬间整个电池包电压瞬间掉到 3V 以下,且其启动瞬间的持续时间较长 时,芯片处于工作电压过低状态,为了整个电池包安全,芯片会快速关闭放电 MOSFET,所以上面情况可能 会导致无法启动现象,请适当增加 VDD 处 RC 滤波常数。此处如有特殊应用请联系我们,一般我们的典型 应用原理图都能满足设计需求。
1) 保证在不同电压下短路,短路电流都大于(短路保护阈值 3)/( ),这样能保证在大电流情况下,
最快关闭放电回路,以免出现烧毁器件现象。即(短路保护阈值 3)< (实际短路电流 I)* 2) 放电过流 1 阈值选择,一般会根据实际使用过程中最大电流决定,(放电过流 1 阈值)>(实际使用最大电 流 Imax)* 3) ,一般略大于就可以了,以免出现长时间异常电流,导致放电 MOS 烧毁。

简述
M1056是一款完整的单级锂离子电池采用恒定电流/恒定电压线性充电器。
其底部带有散热片的SOP-8/MSOP-8封装与较少的外部元件数目使得M1056成为便携式应用的理想选择。
M1056可以适合USB电源和适配器电源工作。
M1056采用了内部PMOSFET架构,加上防倒充电路,所以不需要外部隔离二极管,热反馈可对充电电流进行自动调节,以便在大功率操作或高环境温度条件下对芯片温度加以限制。
充电电压固定于4.2V,而充电电流可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1/10时,M1056将自动终止充电循环。
当输入电压(交流适配器或USB电源)被拿掉时,M1056自动进入一个低电流状态,将电池漏电流降至2uA以下。
M1056在有电源时也可置于停机模式,以而将供电电流降至50uA。
M1056的其他特点包括电池温度检测、欠压闭锁、自动再充电和两个用于指示充电、结束的LED状态引脚。
