SAS DISABLE +5V eFUSE WITH INTEGRATED ISOFET

Description

Pin Assignments

The eFuse is a 5V protection device with a bidirectional switch that

incorporates input slew rate control to reduce input surge current and

reverse current detection to prevent discharge to VCC from VOUT.

The eFuse protection features include under voltage lockout, a fixed

2.5A current limit, trimmed fast response over voltage protection and

thermal shutdown. The EN/FAULT line is a tri-state bidirectional

interface that can be used to disable the output by pulling the line low

through an external open drain device. If a thermal fault occurs, the

voltage on the pin will go to an intermediate voltage indicating a fault

and it can be connected to another device to cause simultaneous shut

down. The SAS pin is an ESD protected interface that allows direct

external control of the eFuse. Driving the SAS pin high pulls the

enable line low causing the eFuse to shutdown and enter a low

quiescent current state.

The integrated Isofet latches off when the reverse current is detected.

This can be reset only by triggering the under voltage lock out, by

EN/FAULT pin or when voltage on the output pin (VOUT) falls below

the supply pin voltage (VCC) in AP91352.
