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.
