Ground connection;
Power-switch input voltage; connect a 1 mF or greater ceramic capacitor from IN to GND as close as pos-
sible to the IC.
Active-low open-drain output, asserted during overcurrent, overtemperature or reverse-voltage conditions.
Connect a 10 kW or greater resistor pull-up, otherwise leave unconnected.
Power-switch output; connect a 1 mF ceramic capacitor from OUT to GND as close as possible to the IC
is recommended. A 1 mF or greater ceramic capacitor from OUT to GND must be connected if the USB
requirement (i.e.120 mF capacitor minimum) is not met.
External resistor used to set current-limit threshold; recommended 5 kW < R
Exposed Thermal Pad: Must be soldered to PCB Ground plane
