ADM1812-5AKSZ-REEL

Supervisors Overview

The ADM1812-5AKSZ-REEL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It provides a reset signal when supply voltage drops below a specified threshold, ensuring system reliability during power-up and brown-out events. The device features a fixed 4.63 V threshold voltage for the monitored input. It operates within a supply voltage range of 2.7 V to 5.5 V and includes a typical reset timeout delay of 140 ms. The component is housed in an SC-70-5 surface-mount package and supports industrial temperature ranges.

Supervisors Feature Summary
