TPS27S100 (ACTIVE)

40-V, 100-mOhm Single-Channel Smart High-Side Switch

40-V, 100-mOhm Single-Channel Smart High-Side Switch - TPS27S100
 

Description

The TPS27S100x is a single-channel, fully-protected, high-side switch with an integrated NMOS and charge pump. Full diagnostics and high-accuracy current-monitor 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.
