Overview

NCV8881 Buck Regulator Automotive, Watchdog 1.5 A The NCV8881 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.
