Overvoltage Protection Output. Bypass OUT with a 1µF ceramic capacitor.
Externally connect all OUT together.
Enable Input for OTG Supply Operation
Overvoltage Protection Input. If desired, bypass IN with a 0.1µF ceramic capacitor
as close to the device as possible. Externally connect all IN together.
1.8V Logic Output. ACOK is driven high after input voltage is stable between
minimum V_IN and V_OVLO when OTG_EN = 0. Connect a pulldown resistor from
ACOK to ground.
Overvoltage Lockout Input. Connect OVLO to GND to use internal OVLO threshold.
Connect OVLO to a resistor-divider for a different voltage threshold.
Open-Drain Flag Output. ACOK is driven low after input voltage is stable between
minimum V_IN and V_OVLO when OTG_EN = 0. Connect a pullup resistor from
ACOK to the logic I/O voltage of the host system.
Ground
Exposed Pad (TDFN only) Connect EP to ground.
