ATA6025-TAQ

ATA6025-TAQ Datasheet


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 5V 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.
