The FPF3003 input operating range is from 2.3V to 5.5V on BATA and BATB, while ADPIN has a range of 4.6V to 5.5V. Battery Selection The load path can be controlled by the BATSEL pin. When BATSEL is LOW, the system is powered from BATA. When BATSEL is HIGH, BATB powers the system. Figure 36 is state diagram showing how the power path from battery to system is determined. The FPF3003 controls the charging path from the charger to the battery with up to 1.5A and the discharging path from the battery to system load with up to 2.5A. The system or PMIC selects one of two batteries to provide power and enables one of the batteries to be charged by the external battery charger. Power On from ADPIN, BATA, or BATB RESETB = HIGH The FPF3003 has 30s slew-rate control to reduce inrush current when engaged and thermal shutdown protection for reliable system operation. Y Switch to the present battery Battery Presence Detection Either BATAID or BATBID = HIGH N The FPF3003 monitors whether or not a battery is present via the BATAID and BATBID pins. If any of these pins are LOW; FPF3003 recognizes the battery is present. Each pin is connected with an internal LDO output, so no pull-up resistor is required. Y N LOBAT > 0.8V During battery source transition, voltage droop depends on output capacitance and load current condition. Advanced break-before-make operation minimizes the droop with minimum capacitance. At least 10F is a good starting value in design. BATSEL = LOW Primary Battery Under-Voltage Set Switch to BATA Y N Switch to BATB Y FPF3003 monitors the primary battery of BATA for under-voltage condition. Once under-voltage condition is confirmed, the system power source changes from BATA to valid BATB automatically. Figure 36. Power Path from Battery to System The open-drain STAT pin is used to determine which battery powers the system. STAT becomes LOW if BATB is connected to the system. STAT is HIGH (HI-Z) if BATA is connected. The under-voltage threshold level can be programmed with 0.8V of LOBAT and R divider (R1 and R2) as: -1 N Both BATAID and BATBID = LOW Output Capacitor _ 0.8 VOUT Floating Y The internal circuit is powered from the highest voltage source among BATA, BATB, and ADPIN. 1 = 2 N (1) where BATA_LO = Low BATA threshold to set. If 3.4V of BATA is desired, R1/R2=3.25. If R2 is chosen 1M, R1 is 3.25M. Higher R2 is recommended to reduce leakage current from BATA. Figure 35. BATA Under-Voltage Level Setting LOBAT has a 1.3ms of deglitch time to ensure BATA is in true under-voltage rather than transient battery voltage drop during GSM transmission operation.

When CHGSEL is LOW, BATA can be charged from the charger. When CHGSEL is HIGH, BATB can be charged from the charger. The RESETB pin allows the system to be turned off without detaching the battery pack. It has typical 7s delay to avoid transient abnormal signal. Board Layout For best performance, all power traces (BATA, BATB, CHGIN, ADPIN, and VOUT) should be as short as possible to minimize the parasitic electrical effects and the case-to-ambient thermal impedance. The output capacitor should be placed close to the device to minimize parasitic trace inductance. Figure 37.
