Description
The ATA6025 is a monolithic circuit based on Atmel’s smart power BCD60-III technol-
ogy. It is a universal IC for monitoring basic functions of an automotive application. It is
possible to monitor the battery voltage (VKL15) and an external 5 V voltage regulator.
With the independent watchdog the correct function of a microcontroller can be
observed. If a failure occurs, the output NOTL switches to high after a time delay. Dur-
ing standby mode the current consumption is reduced to a minimum.
