MAX16020PTEZ+

Supervisors Overview

The MAX16020PTEZ+ is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 3.1 V to 5.5 V and features a threshold voltage of 3.1 V. The device provides active high, active low, and open drain outputs with a reset delay time of 215 ms. It includes a manual reset function, a watchdog timer, and battery backup switching capabilities. Designed for surface mount installation in a TQFN-16 package, it supports chip enable signals and monitors one input. The component functions reliably across an operating temperature range of -40°C to +85°C while consuming only 3.4 µA of quiescent current.
