XC5101-1A线性锂离子电池充电器

XC5101_______________________________________________________XC5101- 1A Linear Li-Ion Battery Charger GENERAL DESCRIPTIONThe XC5101 is a complete constant current &constant voltage linear charger for single cell lithium-ion batteries. Its SOP package and low external component count make the XC5101 ideally suited for portable applications.Furthermore, the XC5101 is specifically designed to work within USB power 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 dietemperature during high power operation or high ambient temperature. The charge voltage is fixed at 4.21V, and the charge current can beprogrammed externally with a single resistor. The XC5101 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 XC5101 automatically enters a low current state, dropping the battery drain current to less than 2uA. The XC5101 can be put into shutdown mode, reducing the supply current to 50uA.Other features include Battery temperature monitor, under-voltage lockout, automaticrecharge and two status pins to indicate charge and charge termination.FEATURESProgrammable Charge Current Up to 1000mANo MOSFET, Sense Resistor or Blocking DiodeComplete Linear Charger in SOP Package for single Cell Lithium-Constant-Current/Constant-Voltage Operation with Thermal Regulation to Maximize ChargeRate Without Risk of OverheatingCharges Single Cell Li-Ion Batteries Directly fromPreset 4.21V Charge Voltage with ±1% AccuracyCharge Current Monitor Output for Gas GaugingCharge state pairs of output, no battery and faultC/10Soft-Available in SOP8-PP PackageAPPLICATIONSCellular Telephones, PDAs, MP3 /MP4 PlayersCharging Docks and Cradles Bluetooth 、GPS ApplicationsFigure1Typical Application Circuit深圳市思微半导体有限公司XC5101 ______________________________________________________________________________________________________________________ ORDERING INFORMATIONPART NUMBER TEMP RANGE VIN VBATCHARGECURRENTPACKAGE PINSXC5101 -40°C to 85°C 4.5~6V 4.21V 1A SOP-PP 8 PIN CONFIGURATIONFigure 2.

When charging in constant-current mode, this pin servos to 1V. In all modes, the voltage on this pin can be used to measure the charge current using the following formula: IBAT = (VPROG/RPROG) x1000.The PROG pin can also be used to shut down the charger. Disconnecting the program resistor from ground allows a 3uA current to pull the PROG pin high. When it reaches the 1.21V shutdown threshold voltage, the charger enters shutdown mode, charging stops and the input supply current drops to 50uA. This pin is also clamped to approximately 2.4V. Driving this pin to voltages beyond the clamp voltage will draw currents as high as 1.5mA. Reconnecting RPROG to ground will return the charger to normal operation.GND (PIN 3): Ground.VCC (PIN 4): Positive Input Supply Voltage.Provides power to the charger, VCC can range from 4.25V to 6.5V and should be bypassed with at least a 10uF capacitor. When VCC drops to within 30mV of the BAT pin voltage, the XC5101 enters shutdown mode, dropping IBAT to less than 2uA.BAT (PIN 5): Charge Current Output.Provides charge current to the battery and regulates the final float voltage to 4.2V. An internal precision resistor divider from this pin sets the float voltage which is disconnected in shutdown mode.STDBY (PIN 6): The completion of battery charging instructions side.When the battery charge is complete, STDBY pulled low by internal switches, indicating the completion of charging. In addition, STDBY pin will be in a high-impedance state.CHRG (PIN 7): Open-Drain Charge Status Output.When the battery is charging, the CHRG pin is pulled low by an internal N-channel MOSFET. When the charge cycle is completed, CHRG pin will be in a high-impedance state.CE (PIN 8): Chip enable input.High input level will make XC5101 in normal working condition; low input level so that XC5101 is prohibited charging status.

performance of high and low side gate drivers cannot be achieved without taking due considerations during circuit board layout.Following points are emphasized.1.A low ESR /ESL capacitor must be connected close tothe IC,and between V DD and V SS pins and between HB and HS pins to support high peak currents being drawn from VDD during turn-on of the external MOSFET.2.To prevent large voltage transients at the drain of the topMOSFET,a low ESR electrolytic capacitor must be con-nected between MOSFET drain and ground (V SS ).3.In order to avoid large negative transients on the switchnode (HS)pin,the parasitic inductances in the source of top MOSFET and in the drain of the bottom MOSFET (synchronous rectifier)must be minimized.4.Grounging Considerations:a)The first priority in designing grounding connections is to confine the high peak currents from charging and discharging the MOSFET gate in a minimal physical area.This will decrease the loop inductance and mini-mize noise issues on the gate terminal of the MOSFET.The MOSFETs should be placed as close as possible to the gate driver.b)The second high current path includes the boot-strap capacitor,the bootstrap diode,the local ground referenced bypass capacitor and low side MOSFET body diode.The bootstrap capacitor is recharged on the cycle-by-cycle basis through the bootstrap diode from the ground referenced V DD bypass capacitor.The re-charging occurs in a short time interval and involves high peak current.Minimizing this loop length and area on the circuit board is important to ensure reliable operation.Power Dissipation ConsiderationsThe total IC power dissipation is the sum of the gate driver losses and the bootstrap diode losses.The gate driverlosses are related to the switching frequency (f),output load capacitance on LO and HO (C L ),and supply voltage (V DD )and can be roughly calculated as:P DGATES =2•f •C L •V DD 2There are some additional losses in the gate drivers due to the internal CMOS stages used to buffer the LO and HO outputs.The following plot shows the measured gate driver power dissipation versus frequency and load capacitance.At higher frequencies and load capacitance values,the power dissipation is dominated by the power losses driving the output loads and agrees well with the above equation.This plot can be used to approximate the power losses due to the gate drivers.Gate Driver Power Dissipation (LO +HO)V CC =12V,Neglecting Diode Losses2008880520088804FIGURE 3.LM5100/LM51019Power Dissipation Considerations(Continued)The bootstrap diode power loss is the sum of the forward bias power loss that occurs while charging the bootstrap capacitor and the reverse bias power loss that occurs during reverse recovery.Since each of these events happens once per cycle,the diode power loss is proportional to rger capacitive loads require more current to recharge the bootstrap capacitor resulting in more losses.Higher input voltages (V IN )to the half bridge result in higher reverse recovery losses.The following plot was generated based on calculations and lab measurements of the diode recovery time and current under several operating conditions.This can be useful for approximating the diode power dissipation.Diode Power Dissipation V IN =80V20088806Diode Power Dissipation V IN =40V20088807The total IC power dissipation can be estimated from the previous plots by summing the gate drive losses with the bootstrap diode losses for the intended application.Because the diode losses can be significant,an external diode placed in parallel (refer to Figure 4)with the internal bootstrap diode can be helpful in removing power from the IC.For this to be effective,the external diode must be placed close to the IC to minimize series inductance and have a significantly lower forward voltage drop than the internal diode.20088808FIGURE 4.LM5101Driving MOSFETs Connected in Half-Bridge ConfigurationL M 5100/L M 5101 10LM5100/LM5101
