TPS27S100BPWPR Description

The TPS27S100BPWPR is a single-channel high-side switch with an integrated NMOS and charge pump that is fully protected. Intelligent load control is enabled by full diagnostics and high-accuracy current-monitoring features. The overall system's reliability is considerably improved by an adjustable current-limit function. Both digital fault status and analog current monitor output are supported by the TPS27S100BPWPR diagnostic reporting. It stands out from the competition thanks to its accurate current monitor and adjustable current limit.
