MC12XS3: 12 V Automotive Exterior Lighting Multi eXtreme Switch

Overview

The NXP^® 12XS3 eXtreme Switch Generation 3 12 V devices are SPI-controlled smart high side switches providing diagnostics for the switch, light source and wiring harness, as well as comprehensive fault management and control of the loads without complex software.

Programmable multi-step latched overcurrent shutdown protection
Minimizes the thermal stress within the device during an overload condition, reducing the junction temperature rise and improving reliability
Packaged in a PQFN package and a SOICW-EP package
Low RDS(ON) and large integration enable savings in module size, power dissipation and total system cost
