Pin Description

FUNCTION

Overvoltage-Protection Input. Bypass IN with a 1µF ceramic capacitor as close as possible to the device

to obtain ±15kV HBM ESD protection. No capacitor required to obtain ±2kV HBM ESD protection.

Voltage Input Good Open-Drain Output. VOK is low impedance when OEN is driven low after the

debounce time is expired (2.2V < VIN < VOVLO).

USB Data Line with ESD Protection

Overvoltage Protection Active-Low Enable Input. Drive OEN high to disconnect OUT from IN.

Low-Dropout Active-Low Enable Input.

Charger Detection Open-Drain Output. CDET is low if D+ and D- are shorted.

Ground

Overvoltage Switch Output. Bypass OUT with a 0.1µF ceramic capacitor as close as possible to the

device.

Low-Dropout Power Output. Bypass LOUT with a 1µF ceramic capacitor as close as possible to the

device.
