The Microchip Technology ATA5021-GAQW is a digital window watchdog timer designed for monitoring microcontrollers in safety-critical applications. It operates with low current consumption, drawing less than 25µA.
This IC features an RC oscillator and internal reset during power-up and supply voltage drops (POR). It offers both a "short" trigger window for active mode and a "long" trigger window for sleep mode, with cyclical wake-up capabilities. The device includes a trigger input, a single wake-up input, a reset output, and an enable output.
The ATA5021-GAQW is suitable for microcontrollers operating in both full-power and sleep modes. Its integrated voltage monitoring provides a complete monitoring solution for micro-systems in automotive and industrial applications. The device is supplied in an 8-SOIC package and supports surface mount.
Key electrical characteristics include an adjustable/selectable reset timeout and an active high reset output. The output can be open drain or open collector. The operating temperature range is -40°C to 125°C (TA).
