ADM812TART-REEL7

Supervisors Overview

The ADM812TART-REEL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as a reset generator IC. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 3.08 V with an accuracy of 1.5%. The device provides an active high output type and includes a manual reset function, while lacking watchdog timer or battery backup switch capabilities. It exhibits a reset delay time of 560 ms and consumes a working power supply current of 15 uA. The overvoltage threshold is specified at 3.14 V, with maximum power dissipation of 200 mW. It supports surface mount installation in an SOT-143-4 package and functions across a temperature range from -40 C to +85 C.
