AC 5 I Charge input voltage from AC adapter, connect 10 µF capacitor to ground BAT/OUT 16 I/O Charge current output BAT/OUT 17 I Battery input to DC-DC converter CE 15 I Charge enable input (active low) EN 4 I Enable input for DC-DC converter; EN=HIGH for device enable Feedback pin for DC-DC converter; connect to voltage divider for bq25015, FB 2 I or connect to system OUT voltage for bq25017 PWM control input for the DC-DC converter. A high on FPWM = forced PWM mode. A low = power save FPWM 20 I mode. ISET1 12 I Charge current set point for AC input and precharge and taper set point for both AC and USB ISET2 13 I Charge current set point for USB port (High = 500 mA, Low = 100 mA, High-Z = disable USB charge) NC 1, 10, 11 – No connect. These pins must be left floating. PG 14 O Power good status output (active low, open-drain) STAT1 7 O Charge status output 1 (open-drain) STAT2 8 O Charge status output 2 (open-drain) SW 19 O Phase node of the DC/DC converter; connect series inductor and capacitor to ground USB 6 I Charge input voltage from USB adapter; connect to 10 µF capacitor to ground Ground Input. Also note that there is an internal electrical connection between the exposed thermal pad and VSS pins of the device. The exposed thermal pad must be connected to the same potential as the VSS 3, 9, 18 – Vss pin on the printed circuit board. Do not use the thermal pad as the primary ground input for the device. All VSS pins must be connected to ground at all times. 8 Submit Documentation Feedback |
