MAX16020LTEL+T

Supervisors Overview

The MAX16020LTEL+T is a low-power supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features a single monitored input with a threshold voltage of 3.1V and an overvoltage threshold of 3.19V. The device operates within a supply voltage range of 1.53V to 5.5V, consuming only 1.2µA of quiescent current. It provides active high and active low push-pull outputs, includes manual reset capability, and incorporates a watchdog timer and battery backup switch. The reset delay time is specified at 215ms, and it supports power-fail detection. The component is housed in a TQFN-EP-16 package and functions reliably across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary
