APL3208A/B/C Li+ Charger Protection IC with Integrated P-MOSFET Features • • • • • • • • • • • Input Over-Voltage Protection Current-Limit Protection Battery Over-Voltage Protection High Immunity of False Triggering High Accuracy Protection Threshold A Built-In P-MOSFET Available with 3 Versions of Charging Current: 450mA, 550mA, 650mA Thermal Shutdown Protection Available in TDFN2x2-8 and TSOT-23-6A Packages “Lithium-Safe” Criteria Lead Free and Green Devices Available (RoHS Compliant) General Description The APL3208A/B/C provides complete Li+ charger protection against Input over-voltage, battery over-voltage, and the charge current limit. When the input OVP or the battery OVP is over the threshold, the IC removes the power from the charging system by turning off an internal switch. When the current via the internal switch surpasses the current limit threshold, the current will be clamped in a constant level to provide a constant current for battery charging usage. All protections also have deglitch time against false triggering due to voltage spikes or current transients. The APL3208A/B/C integrates a P-MOSFET with the body diode reverse protection to replace the external power bipolar transistor and Schottky diode for charger function of the Infineon ULC2 mobile phones. When the CHG_DET voltage drops below VBAT+20mV, the internal power select circuit will reverse the body diode’ terminal to pres vent a reverse current flowing from the battery back to the CHG_DET pin. The APL3208A/B/C provides complete Li+ charger protections and save the external MOSFET and Schottky diode for the Infineon ULC2 mobile phones.

General Application Circuit C opyright © A NPEC Electronics Corp. Rev. A.2 - Nov., 2009 8 www.anpec.com.tw APL3208A/B/C Function Description ACIN Power-On-Reset (POR) The APL3208A/B/C has a built-in power-on-reset circuit to keep the output shutting off until internal circuitry is operating properly. The POR circuit has hysteresis and a de-glitch feature so that it will typically ignore undershoot transients on the input. When the input voltage exceeds the POR threshold and after 8ms blanking time, the output voltage starts a soft-start to reduce the inrush current. ACIN Over-Voltage Protection (OVP) The input voltage is monitored by the internal OVP circuit. When the input voltage rises above the input OVP threshold, the internal FET will be turned off within 1ms to protect the connected system on OUT pin. When the input voltage returns below the input OVP threshold minus the hysteresis, the FET is turned on again after 8ms recovery time. The input OVP circuit has a 200mV hysteresis and a recovery time of TON(OVP) to provide noise immunity against transient conditions. Battery Over-Voltage Protection The APL3208A/B/C monitors the VBAT pin voltage for battery over-voltage protection. The battery OVP threshold is internally set to 4.35V. When the VBAT pin voltage exceeds the battery OVP threshold for a blanking time of TB , the internal power FET is turned off. When the VBAT (BOVP) voltage returns below the battery OVP threshold minus the hysteresis, the FET is turned on again. The APL3208A/ B/C has a built-in counter. When the total count of battery OVP fault reaches 16, the FET is turned off permanently, requiring a VACIN POR again to restart. Current-Limit Protection The APL3208A/B/C provides a current-limit protection function. When the current via the internal switch surpasses the current limit threshold, the current will be clamped to a constant level to provide external battery charging current. Over-Temperature Protection When the junction temperature exceeds 160oC, the internal thermal sense circuit turns off the power FET and allows the device to cool down. When the device’ juncs tion temperature cools by 40 oC, the internal thermal sense circuit will enable the device, resulting in a pulsed output during continuous thermal protection. Thermal protection is designed to protect the IC in the event of over temperature conditions. For normal operation, the junction temperature cannot exceed TJ=+125oC. Internal P-MOSFET The APL3208A/B/C integrates a P-channel MOSFET with the body diode reverse protection to replace the external power bipolar transistor and Schottky diode for the Infineon ULC2 mobile. The body diode reverse protection prevents a reverse current flowing from the battery back to the CHG_DET pin. During power-on, when CHG_DET voltage rises above the VBAT voltage by more than 120mV, the body diode of the P-channel MOSFET is forward biased from OUT to CHG_DET, and P-MOSFET is controlled by the external CHG_SW voltage. When the CHG_DET voltage drops below VBAT+20mV, the body diode of the P-channel MOSFET is forward biased from CHG_DET to OUT and P-channel MOSFET is turned off. When any of input OVP, battery OVP, is detected,the internal P-channel MOSFET is also turned off. C opyright © A NPEC Electronics Corp. Rev.

A.2 - Nov., 2009 10 www.anpec.com.tw APL3208A/B/C Application Information RBAT Selection Connect the VBAT pin to the positive terminal of battery through a resistor RBAT for battery OVP function. The RBAT limits the current flowing from VBAT to battery in case of VBAT pin is shortened to ACIN pin under a failure mode. The recommended value of RBAT is 200kΩ . In the worse case of an IC failure, the current flowing from the VBAT pin to the battery is: (30V-3V)/ 200kΩ =135µA where the 30V is the maximum ACIN voltage and the 3V is the minimum battery voltage. The current is so small and can be absorbed by the charger system. Capacitor Selection The input capacitor is for decoupling and prevents the input voltage from overshooting to dangerous levels. In the AC adapter hot plug-in applications or load current step-down transient, the input voltage has a transient spike due to the parasitic inductance of the input cable. A 50V, X7R, dielectric ceramic capacitor with a value between 1µF and 4.7 µF placed close to the ACIN pin is recommended. The output capacitor of CHG_DET is for CHG_DET voltage decoupling. And also can be as the input capacitor of the charging circuit. At least, a 1µF, 10V, X7R capacitor is recommended. Layout Consideration In some failure modes, a high voltage may be applied to the device. Make sure the clearance constraint of the PCB layout must satisfy the design rule for high voltage. The exposed pad of the TDFN2x2-8 performs the function of channeling heat away. It is recommended that connect the exposed pad to a large copper ground plane on the backside of the circuit board through several thermal vias to improve heat dissipation. The input and output capacitors should be placed close to the IC. The high current traces like input trace and output trace must be wide and short. C opyright © A NPEC Electronics Corp. Rev.
