ADM809MARTZ-REEL7

Supervisors Overview

The ADM809MARTZ-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It operates within a supply voltage range of 1 V to 5.5 V and features a push-pull output configuration. The device provides a reset threshold voltage of 4.38 V with an accuracy of 1.5% and an overvoltage threshold of 4.45 V. It includes a fixed reset delay time of 240 ms and consumes a typical operating supply current of 60 uA. The component is housed in a SOT-23-3 package, supports surface-mount installation, and functions reliably across an extended temperature range from -40°C to +125°C.
