MAX16020PTEY+T

Supervisors Overview

The MAX16020PTEY+T is a low-power microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.7V to 5.5V and features a fixed threshold voltage of 3.1V for monitoring input signals. The device provides active high, active low, and open drain output types, incorporating manual reset functionality and an integrated watchdog timer with battery backup switch capabilities. It includes a reset delay time of 215ms and consumes only 3.4µA of quiescent current. Designed for surface mount installation in TQFN-16 packages, it supports power-fail detection and chip enable signals across an operating temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Integrates manual reset pushbutton interface and watchdog timer for system reliability
• Supports battery backup switching to maintain critical data during power transitions
• Offers configurable output states including active high, active low, and open drain configurations

Supervisors Applications

• Portable consumer electronics requiring low standby current
