Description

The ATA6025 is a monolithic circuit based on Atmel's smart power BCD60-III technology.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. During standby mode the current consumption is reduced to a minimum.
