Atmel's new member of its watchdog IC family has increased functionality that helps to make automotive applications safer. The ATA6025, manufactured on the high-voltage BCDMOS process, supports operations up to 40 V and is optimised for applications in harsh environments. The new device is especially designed for automotive applications where low power consumption in standby mode is required, for example, a vehicle's external lighting systems.
Compared to conventional watchdog ICs, Atmel says the ATA6025 provides extended functionality. The integrated fail-safe function (push-pull driver) helps to avoid failures of safety-critical car functions when the watchdog is not triggered correctly. For example, if the microcontroller controlling a car's lighting systems fails, the ATA6025 takes over this function and ensures that the lights remain switched on. Further add-on functions are the ATA6025's under- and overvoltage detection and a dedicated input (ignition pin) to enable low-power standby mode. In standby mode, the watchdog IC ATA6025 has a current consumption of less than 100 µA.
