Source connection for the internal low-side boost converter power switch. Connect to GND PGND 1 P with a low impedance connection to the input and output capacitors. IN 2 I Input supply voltage for boost converter. EN 3 I Enable input for boost converter. Tie to IN to enable. GND 4 P Control / logic ground. Must be tied to PGND close to the IC externally. ILIM1 5 I Program the nominal USB1 switch current-limit threshold with a resistor to GND. ILIM2 6 I Program the nominal USB2 switch current-limit threshold with a resistor to GND. /FAULT1 7 O Active low USB1 fault indicator (open drain). ENUSB1 8 I Enable input for the USB1 switch. Tie to IN or AUX to enable. RESET 9 O Active low LDO output good indicator (open drain). LDOOUT 10 O Fixed 3.3-V LDO output. Connect a low-ESR ceramic capacitor from LDOOUT to GND. LDOIN 11 I Input supply voltage for LDO. Connect to AUX. ENLDO 12 I Enable input for the LDO. Tie to AUX to enable. /FAULT2 13 O Active low USB2 fault indicator (open drain). ENUSB2 14 I Enable input for the USB2 switch. Tie to IN or AUX to enable. USB2 15 O Output of the USB2 power switch. Connect to the USB2 port. USB1 16 O Output of the USB1 power switch.
