MAX6709FUB+T

Supervisors Overview

The MAX6709FUB+T is a low-voltage, high-accuracy quad voltage monitor manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2 V to 5.5 V and features four independent monitoring channels with open-drain outputs. The device provides fixed threshold voltages including 1.8 V, 2.5 V, 3 V, 3.3 V, and 5 V, alongside adjustable options for under-voltage (2.13 V, 2.85 V) and over-voltage (2.25 V, 3 V). It consumes 35 uA of quiescent current, offers 2% accuracy, and includes a 30 us reset delay. The component is housed in a uMAX-10 package and functions reliably across an operating temperature range of -40 C to +85 C.
