ATA6025 - WATCHDOG IC

General 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 5V voltage regulator.

Key Features

  • Watchdog Adjustable.
  • Over- and Undervoltage Detection of Vcc = 5V.
  • Standby Modes On/Off via Ignition Pin VKL15.
  • Internal Time Delay for Output Signal.
  • Push-pull Output Driver.
  • Interference and Damage Protection According to ISO/CD 7637.
  • ESD Protection Watchdog IC 1.

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 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.
