3 Description

The TPS27S100x is a single-channel, fully-protected,

high-side switch with an integrated NMOS and charge

pump. Full diagnostics and high-accuracy currentmonitor

features enable intelligent control of the load.

An adjustable current-limit function greatly improves

the reliability of the whole system. The device

diagnostic reporting has two versions to support both

digital fault status and analog current monitor output.

Accurate current monitor and adjustable current limit

features differentiate it from the market.
