R1 and C1 are used to stabilize the supply voltage of the AP9234L. The recommended range of R1 value is 330 to 470 and C1 value is 10nF to 1000nF, typical value is 100nF. R2 should be connected between P- to VM sense terminal to monitor the status of charger and the charge/discharge current. The R2 should be between 300 and 4k, typical value is 2.7k. R1 and R2 are also used as current limit resistors if the battery or charger is connected reversely. Polarity reversing may cause the power consumption of R1 and R2 to go over their power dissipation rating, therefore R1 and R2 values should be selected appropriately for the actual application. If R2 is more than 4k resistor, charge may not be off due to the voltage drop on R2. For power down mode (please contact Diodes Inc. sales team), when first connecting AP9234L system board to the battery, it is necessary to use charger or to short P- to the battery negative polarity. Once the AP9234L is activated, the charger or connection can be removed, otherwise the battery cannot discharge current through system board. The values selected should follow the recommended typical range mentioned above.

AP9234L Document number: DS38205 Rev. 1 - 2 7 of 14 www.diodes.com December 2015 (c) Diodes Incorporated 125 AP9234L Application Information ADVANCED INFORMATION Operation Mode 1. Normal Status The AP9234L monitors the battery voltage between the VDD pin and VSS pin as well as the voltage difference between the V M pin and VSS pin to control battery charging and discharging. When the battery voltage is between overdischarge detection voltage (V DL) and overcharge detection voltage (VCU) as well as the VM pin voltage is between the charge overcurrent detection voltage (V COC) and discharge overcurrent detection voltage (VDOC), the AP9234L will turn on discharging and charging MOSFET, then the battery can charge and discharge freely in this condition. RVMD does not connect to VDD pin and RVMS does not connect to VSS pin in this status. 2. Overcharge Status When the battery voltage is more than VCU during charging status and the detection lasts for the overcharge detection delay time (tCU) or longer, the AP9234L turns off the charging MOSFET to stop charging. RVMD and RVMS are not connected in overcharge status. When VM pin voltage is lower than VDOC and battery voltage falls below VCL, the AP9234L will release from overcharge status. When VM pin voltage is equal or more than VDOC and battery voltage falls below VCU, the AP9234L will release from overcharge status. 3. Overdischarge Status When the battery voltage is less than VDL during discharging status and detection continues for the overdischarge detection delay time (tDL) or longer, the AP9234L turns off the discharging MOSFET to stop discharging. In overdischarge status, RVMS is not connected, but RVMD is connected to VDD and VM pin voltage is pulled up to VDD by RVMD. For power-down mode option (ask local sales office), IC recovers normal status from overdischarge status only by charger charge to battery. When VM pin voltage to VSS pin voltage is less than typical -0.7V and the battery voltage rises over VDL, the AP9234L will release from overdischarge status, if VM pin voltage to VSS pin voltage is higher than typical -0.7V, the AP9234L will release from overdischarge status until the battery voltage rises over VDU For auto-wake-up version, the AP9234L recovers normal status from overdischarge status requires that either of two conditions should be satisfied. If charger is connected: The AP9234L overdischarge status is released in the same way as AP9234Ls. If no charger is connected: 1). The battery voltage reaches the overdischarge release voltage (VDU) or higher. 2). Maintains continuous time more than overdischarge release delay time tDLR 4. Discharge Overcurrent and Short Current Status When battery is in discharge overcurrent status, if the voltage of the VM pin to VSS pin is equal or more than VDOC to VSHORT and detection lasts for the discharge overcurrent detection delay time (tDOC) or longer, the AP9234L turns off the discharging MOSFET to stop discharging. When the battery is in short current status, if the voltage of the VM pin to VSS pin is equal to or more than VSHORT, and detection lasts for the short current detection delay time (tSHORT) or longer, the AP9234L turns off the discharge MOSFET to stop discharging. In discharge overcurrent or short current status, RVMS is connected to VSS but RVMD is not connected., the voltage of VM pin is almost equal to VDD as long as the load is connected. When the load is disconnected, the voltage of V M pin will become almost equal to VSS(due to RVMS being connected) and then the AP9234L will release from discharge overcurrent or short current status. 5. Charge Overcurrent Status When the battery is in charge overcurrent status, if the voltage of the VM pin to VSS pin is equal to or less than VCOC for the charge overcurrent detection delay time (tCOC) or longer, the AP9234L turns off the charging MOSFET to stop charging. 6. 0V Battery Charging Function This function is available as an option and can be factory set internally. AP9234L has this function built in. 0V charging function permits charger to recharge the battery whose voltage is 0V due to self-discharge. If 0V charging function is not present, the device will prevent charger to recharge the battery whose voltage is 0V due to self-discharge. (If a device without 0V charging function is needed, please contact Diodes sales team) 7. Overvoltage Charger Detection Circuit This function is used to monitor the charger voltage between the V DD pin and VM pin, and when this voltage exceeds overvoltage charger detection voltage (8.0V Typ.), the AP9234L will turn off charging MOSFET, when this voltage drops below overvoltage charger release voltage (7.3V Typ.), it then turns on charging MOSFET. There are no delay times set for detection and release. 8. Power-Down Mode or Auto-Wake-Up Function Option In device with power-down function, during power-down mode, AP9234L enters overdischarge status. The IC enters sleep mode and the current consumption becomes very low, typically 0.1uA. To release from power-down status to the normal status, charger connection is required. In device with auto-wakeup mode, the IC remains active in the overdischarge state. The IC is released into the normal state by the operation that increases the battery voltage more than overdischarge release voltage.
