The MAX6420UK29+T is a low-power microprocessor supervisor circuit designed to monitor system voltages. It provides an active-low reset output that asserts when the supply voltage or RESET IN falls below its reset threshold. This device is capable of monitoring dual-voltage systems, with one threshold set at 2.925V and an adjustable option.
The supervisor features an open-drain reset output and is housed in a compact SOT-23-5 package, suitable for surface mounting. It operates over a wide temperature range of -40°C to 125°C. The reset timeout period is externally adjustable via a capacitor, offering design flexibility.
Applications for this supervisor include critical microprocessor monitoring in automotive systems, medical equipment, intelligent instruments, and portable devices. Its dual-voltage monitoring capability makes it suitable for embedded controllers and battery-powered computers.
