ADM811LART-REEL7

Supervisors Overview

The ADM811LART-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 up to 5.5 V and features a push-pull output type with manual reset capability. The device provides a fixed reset delay time of 560 ms and includes an overvoltage threshold detection feature at 4.72 V. It functions reliably across an extended temperature range from -40°C to +85°C, drawing a typical operating supply current of 15 µA. The component is housed in a compact SOT-143-4 surface-mount package.

Supervisors Feature Summary
