NCV8881PWR2G Description

The NCV8881PWR2G consists of a Buck switching regulator (SMPS) with a combination SMPS output Undervoltage monitor and CPU watchdog circuit. In addition, two fixed?voltage low dropout regulator outputs are provided and share an LDO output voltage status output. Once enabled, regulator operation continues until the Watchdog signal is no longer present. The NCV8881PWR2G is intended for Automotive, battery?connected applications that must withstand a 40 V load dump.
