MAX820RESE+

Supervisors Overview

The MAX820RESE+ is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for microprocessor and nonvolatile memory applications. It operates within a supply voltage range of 2.75 V to 5.5 V and features a single monitored input with active high, active low, and push-pull output types. The device includes manual reset functionality, a watchdog timer, and power-fail detection, while lacking battery backup switching. It has a reset delay time of 280 ms and consumes 150 uA of operating current. The component supports chip enable signals and offers an overvoltage threshold of 2.7 V with a maximum power dissipation of 762 mW. It is housed in a SOIC-Narrow-16 package and functions reliably across a temperature range of -40 C to +85 C.
