DS1819CR-10-U

Supervisors Overview

The DS1819CR-10-U is a MicroMonitor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1 V to 5.5 V and monitors a single input channel. The device features a threshold voltage of 2.925 V with an accuracy of 10%. It provides active high and active low push-pull outputs, ensuring flexible interface compatibility. A minimum reset timeout of 140 ms is guaranteed. The component functions reliably across a temperature range of -40°C to +85°C and is housed in a compact SOT-23-5 surface-mount package.

Supervisors Feature Summary
