MAXIM INTEGRATED / ANALOG DEVICES MAX6303CUA microcontroller supervisor

The MAX6303CUA+ is a comprehensive +5V low-power microprocessor supervisory circuit housed in an 8-pin µMAX package. It offers adjustable reset and watchdog functions, with the reset threshold settable above 1.22V via external resistors. The reset and watchdog timeout periods are adjustable through external capacitors, and a watchdog select pin extends the watchdog timeout to 500 times. The reset feature is immune to power supply transients. Suitable for use in intelligent instruments, battery-powered computers and controllers, embedded systems, and critical microprocessor monitoring applications, it supports a supply voltage range from 1V to 5.5V, operates within 0°C to 70°C, and consumes only 4µA of current (no load). The device provides an active-low, push-pull reset output, with a typical reset timeout of 4ms and a watchdog timeout of 2 seconds. The reset is asserted at or above 1V VCC.
