ADM809JART-REEL7

Supervisors Overview

The ADM809JART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed for monitoring single-input power rails. It features a push-pull output and operates within a maximum supply voltage of 5.5 V. The device has a threshold voltage of 4 V with an accuracy of 1.5%. It includes a reset delay time of 240 ms and lacks manual reset, watchdog timer, or battery backup switch functions. The component draws a working supply current of 60 uA and detects overvoltage at 4.06 V. It is housed in a SOT-23-3 package and supports surface mount installation. The operational temperature range spans from -40 C to +125 C.

Supervisors Feature Summary

• Provides voltage supervision for single-input applications with high accuracy.
