TPS25940-Q1

SLVSDJ0D –MAY 2016–REVISED SEPTEMBER 2018

TPS25940x-Q1 2.7-V to 18-V eFuse with Integrated Short-to-Battery Protection

1 Features

3 Description

The TPS25940x-Q1 eFuse Power Switches are

compact, feature rich power management devices

with a full suite of protection functions. The wide

operating range allows control of many popular DC

bus voltages. Integrated back-to-back FETs provide

bidirectional current control making the device well

suited for systems with load side holdup energy that

must not drain back to a failed supply bus.

Qualified for Automotive Applications

•

AEC-Q100 Qualified With the Following Results:

–

Device Temperature Grade 1: –40°C to

+125°C Ambient Operating Temperature

Range

–

Device HBM ESD Classification Level 2

Device CDM ESD Classification Level C5

Load, source and device protection are provided with

many programmable features including overcurrent,

Programmable dV_o/dt Control

The TPS25940x-Q1 monitor V_(IN)and V_(OUT)to

provide true reverse current blocking when V_(IN)

(V_(OUT)– 66 mV). This function supports supply bus

protection from over-voltages during output short to

battery faults.
