PIN FUNCTION DESCRIPTION
Pin
Symbol
Description
1, 2
Input −
Negative input voltage to the device. This is used as the internal reference for the IC.
3
Current Limit This pin is shorted to the Input − pin for maximum current limit setting. If a reduced current limit level is
desired, a series resistor is added between this pin and the Input − pin.
4, 8
Drain
Drain of power FET, which is also the switching node for the load.
5
OVLO
The overvoltage shutdown point is programmed by a resistor from this pin to the Input + supply.
6
UVLO/ENABLE A resistor from Input + to the UVLO pin adjusts the voltage at which the device will turn on. An open drain
device can be connected to this pin, which will inhibit operation, when in its low impedance state.
7
Input +
Positive input voltage to the device.

Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the
Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect
device reliability.
1. Applied between Input + and Input − pins only, and using an external 68 V bi−directional TVS device (P6SMB68AT3) connected across these
pins.
