Input. IN is the power input for the OVP charge pump. Bypass IN to GND with a 1µF or larger
capacitor.
Active-Low Enable Input. Drive EN high to turn off the external MOSFET. Driving EN low activates
the OVP circuitry and turns on the external MOSFET.
Gate Drive Output. GATE is the output of an on-chip OVP charge pump. When V
V
Internal Current-Limited Switch Terminal. Connect BTA to the source of the external n-channel
MOSFET. BTA is the power input for the entire device (except the OVP charge pump). Bypass BTA
to GND with a 0.1µF capacitor as close to the device as possible for proper operation.
Active-Low Internal Current-Limited-Switch Control Input. Drive CB high to turn on the internal
switch, pull CB low to turn off the internal switch.
Ground
Internal Current-Limited-Switch Output. Bypass BTB to GND with 0.1µF capacitor as close to the
device as possible.
Active-Low Open-Drain Internal Current-Limited Flag Output. FLAGI asserts low when the current
is at the limit for longer than the blanking time. FLAGI is disabled when EN goes high.
No Connection. Not internally connected.
Active-Low Open-Drain IN-Overvoltage Flag Output. OV goes low when an
undervoltage/overvoltage fault occurs at IN. OV is disabled when EN goes high.
Exposed Pad. EP is internally connected to GND. Correct EP to a large ground plane to act as a
heat sink, but do not use EP as the only electrical ground connection.
OVLO
, GATE is driven high to turn on the external n-channel MOSFET.
