Function

25 - 32

VOUT

Output voltage of the eFuse. All pins must be connected together on the PCB

D_OC

Output pin, driven low if the current set-point is exceeded. It is a 5 V compliant open

drain output

ON / PD

Enable/disable pin. This pin is internally pulled up. Pull this pin below the relevant

threshold to shut down the chip. Pull it above threshold to enable the chip. This

pin also commands the output pull-down resistance. A capacitor connected between

this pin and GND can be used to increase the delay during startup

GOK

Gate-OK output pin. It signals that a shutdown, which was not commanded by the

enable pin, has happened. 5 V compliant open drain output, low when device is in a

fault condition

Not internally connected. It can be connected to any voltage

6, 8

NC/reserved

These pins are reserved and must be left floating

NC/reserved

This pin is reserved. If necessary, it can be connected to any voltage up to VIN

VINF

Input voltage for internal circuits. It is connected to VIN through an R-C filter

9 - 16

VIN

Input voltage of the eFuse. All these pins must be connected together and to the

exposed pad

Gate

Gate pin of the internal MOSFET. This pin must be left floating or it can be bypassed

to GND through an external R-C filter, to minimize the risk of oscillation in case of

very small COUT or high input / output inductance

VTEMP

Temperature monitor pin. Bypass to GND with 0.1 μF capacitor
