MAX6721AUTWGD3+T

Supervisors Overview

The MAX6721AUTWGD3+T is a dual-channel ultra-low-voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It monitors two independent voltage inputs with thresholds ranging from 900 mV to 3.3 V and 1.8 V to 5 V. The device features an active low, open-drain output and includes a manual reset input alongside a watchdog timer. It operates within a supply voltage range up to 5.5 V and maintains functionality across temperatures from -40°C to +125°C. Key electrical parameters include a reset delay of 280 ms, a quiescent current of 15 µA, and overvoltage thresholds at 1.71 V and 2.375 V.

Supervisors Feature Summary

• Dual-channel voltage supervision for independent monitoring of multiple power rails
• Integrated watchdog timer with manual reset capability for system reliability
• Ultra-low quiescent current consumption suitable for battery-powered applications
