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.
The NCV8881 is intended for Automotive, battery−connected applications that must withstand a 40 V load dump.
The switching
regulator is capable of converting the typical 9 V to 19 V automotive input voltage range to outputs from 3.
3 V to 8 V at a constant switching frequency, which can be resisto...
