Pin Assignments (Bottom View) Pin Definitions Pin # Name Description A1 BOOTV BOOT. High-side NMOS driver supply. Connect a 10nF capacitor from SW2 to this pin. A2 VREF Bias Regulator Output. Connect to a 1 F capacitor to PGND. This pin supplies the internal gate drive and power supply to the IC while charging. Up to 5 mA of current can be provided from this pin to drive external circuits. This pin is active when either VIN or VBUS are above VBAT. A3 V2V5 2.5 V Regulator. Connect to a 1 F capacitor to PGND. Up to 5 mA can be provided from this pin to drive external circuits. This regulator is powered only when VIN is connected. A4 SDA I 2C Interface Serial Data. This pin should not be left floating. A5 BOOTU BOOT. High-side NMOS driver supply. Connect a 10 nF capacitor from SW1 to this pin. B1, B2 VIN Charger Input Voltage. Bypass with a minimum of 1 F, 16 V capacitor to GND. B3 SCL I 2C Interface Serial Clock. This pin should not be left floating. B4, B5 VBUS USB Input Voltage. Bypass with a 1 F, 16 V capacitor to GND. C1, C2 PMID2 Power Input Voltage for VIN Power Source. Power input to the charger regulator, bypass point for the VIN input current sense, and high-voltage input switch. Bypass with a minimum of 4.7 F, 16 V capacitor to PGND. C3 SRST Safety Reset. When LOW, both safety registers are reset to their default values. When HIGH, the safety registers reset when VBAT drops below VSHORT. C4, C5 PMID1 Power Input Voltage for VBUS Power Source. Power input to the VBUS switching charger regulator, bypass point for the VBUS input current sense, and high-voltage input switch. Bypass with a minimum of 4.7 F, 6.3 V capacitor to PGND. D1, D2 SW2 Switching Node for VIN Charger. Connect to the output inductor. D3 DIS Charge Disable. When this pin is HIGH, charging is disabled and no timers are reset. When LOW, charging is controlled by the I 2C registers. This pin does not affect the 32-second timer. D4, D5 SW1 Switching Node for VBUS Charger and OTG Boost. Connect to the output inductor. E1 –E5 GND Ground. Power return for gate drive and power transistors as well as IC signal ground. The connection from this pin to the bottoms of the CPMID capacitors should be as short as possible. F1 LED Light Emitting Diode Output. Up to 5 mA current source drive from the active PMID indicates the battery is charging.
