MAX6723UTSHD3+T

Supervisors Overview

The MAX6723UTSHD3+T is a triple ultra-low-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors three independent voltage inputs with adjustable thresholds ranging from 900 mV to 3.3 V and 1.8 V to 5 V. The device features an active low open-drain reset output, a watchdog timer, and a reset delay time of 210 ms. Operating within a supply voltage range up to 5.5 V, it consumes only 15 µA of quiescent current. The component is housed in a compact SOT-23-6 package and supports industrial temperature ranges.
