Voltage Input Good Open-Drain Output. VOK is low impedance when OEN is driven low after the
debounce time is expired (2.2V < V
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.
