MAX16020LTES+

Supervisors Overview

The MAX16020LTES+ is a low-power supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as an MPU supervisor with a dedicated battery-backup circuit and chip-enable gating. The device monitors a single input voltage within a supply range of 1.53 V to 5.5 V, featuring a threshold voltage of 3.1 V and an overvoltage threshold of 3.19 V. It operates in a TQFN-EP-16 package with a reset delay time of 215 ms. The component draws a typical operating current of 1.2 uA and supports manual reset functionality alongside watchdog timer capabilities.
