Watchdog supervisor for automotive and industrial rails
The MAX6369KA/V+T is a single-channel watchdog circuit that monitors a system supply voltage and asserts a reset signal if the voltage falls below an adjustable threshold or if the watchdog input is not toggled within a programmable timeout window. Rated for -40°C to 125°C and AEC-Q100 qualified, it suits under-hood ECU, ADAS sensor modules, and industrial motor-drive controllers. The reset output is active low, open-drain, which lets it wire-OR with other supervisor outputs on a shared reset line — common practice in multi-rail systems. Both the voltage threshold and the reset timeout period are adjustable via external resistors, so one part number covers multiple rail voltages and timing requirements without inventory splits.
Lifecycle and sourcing — active, no obsolescence concern
The MAX6369KA/V+T carries an Active product status per the manufacturer's latest lifecycle data. ROHS3 compliant, it is suitable for new designs and production builds without last-time-buy risk.
