MAXIM INTEGRATED / ANALOG DEVICES MAX16997AAUA High-Voltage Watchdog Timer

The MAX16997AAUA+ is a high-voltage watchdog timer housed in an 8-pin µMAX package. It functions as a microprocessor supervisory circuit optimized for high input voltage and low quiescent current applications. The device detects circuit failures, enabling switchover to backup circuitry. It features four independent inputs for reset and watchdog functions—SWT and SRT inputs set timeout periods via external capacitors, while RESETIN/EN monitor voltages with resistive dividers to set reset thresholds. It has a single enable output, a wide 5V to 40V input voltage range, automotive-grade operation from -40°C to 125°C, and supports adjustable reset/watchdog periods. Capacitance-based adjustment, external voltage monitoring, open-drain TTL/CMOS outputs, immunity to narrow WDI pulses, and voltage compatibility make it ideal for system reliability, industrial controls, and safety-critical applications.
