MAX6314US25D1

Supervisors Overview

The MAX6314US25D1+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors power supplies in microprocessor and digital systems with a threshold voltage of 2.5V. The device features a bidirectional RESET output compatible with 68HC11 processors, manual reset input, and a 200ms reset delay time. Operating from 1.2V to 5.5V, it draws only 5µA supply current. Accuracy is specified at 1.8%, with an overvoltage threshold of 2.55V. It operates between -40°C and +85°C in a SOT-143-4 package.
