The Atmel® ATA5021, now part of Microchip Technology, is a digital window watchdog timer built on 0.8µm SOI technology. It is designed to monitor microcontroller operations, especially in safety-critical applications. The device resets the microcontroller if a trigger signal is missing or incorrect within a defined time window. It supports both full-power and sleep modes for microcontrollers and includes power-on reset and supply voltage drop reset functionalities, making it suitable for automotive and industrial micro-systems.
Key features include low current consumption of less than 25µA, an RC oscillator, and adjustable/selectable reset timeout. The ATA5021-TAQY 44 is housed in an 8-SOIC package and is designed for surface mount installation. It operates within a temperature range of -40°C to 125°C (TA).
This watchdog timer is tailored for applications where reliable microcontroller operation is essential. Its trigger input, mode input, wake-up input, reset output, and enable output provide flexible integration into system designs. The device monitors a single voltage and offers an open drain or open collector output type for the reset signal.
