1. Describe

The TPS27S100BPWPT is a single-channel, fully protected, High-Side Switch with Integrated NMOS and Charge Pump. Comprehensive diagnostics and high-accuracy current monitoring functions enable intelligent control of the load. Adjustable current limiting function is greatly improved reliability of the entire system. device Diagnostic reports are supported in two versions at the same time Digital fault status and analog current monitoring outputs. Accurate current monitor and adjustable current limit Features distinguish it from the market.

5. Pin Description

6. Application Information

The device is capable of driving a wide variety of resistive, inductive, and capacitive loads. Full diagnostics and high accuracy current-monitor features enable intelligent control of the load. An external adjustable current limit improves the reliability of the whole system by clamping the inrush or overload current.
