Pin Name Pin Function
VOUT Switch output (Output): The load being driven by the switch is connected to this pin.
NC
No Connect; Pin not used.
ILIMIT
FAULT/
Current Limit (Input): A resistor from this pin to ground sets the current limit value. See
the “setting I_LMIIT” section for details on setting the resistor value.
Fault status (Output): A logic low on this pin indicates the switch is in current limiting, or
has been shut down by the thermal protection circuit. This is an open-drain output
allowing logical OR’ing of FAULT/ outputs from multiple devices.
ENABLE Switch Enable (Input): Logic high on this pin enables the switch.
ENABLE/ Switch Enable (Input): Logic low on this pin enables the switch.
GND
VIN
EP
Ground.
Power input (Input): This pin provides power to both the output power switch and the
internal control circuitry.
Used to remove heat from die. Connect to ground. Use multiple vias to the ground
plane to minimize thermal impedance. See Applications Section for additional
information.
