Pin Functions

PIN DESCRIPTION
NAME NUMBER
BFET 9 Connect this pin to the gate of a blocking NFET. See the Feature Description.
dV/dT 1 Tie a capacitor from this pin to GND to control the ramp rate of OUT at device turn-on.
EN/UVLO 2 This is a dual function control pin. When used as an ENABLE pin and pulled down, it shuts off the internal pass MOSFET and pulls BFET to GND. When pulled high, it enables the device and BFET.
As an UVLO pin, it can be used to program different UVLO trip point via external resistor divider.
GND PowerPAD™ GND
ILIM 10 A resistor from this pin to GND will set the overload and short circuit limit.
OUT 6-8 Output of the device
VIN 3-5 Input supply voltage
