DS1233-15

Supervisors Overview

The DS1233-15 is a voltage supervisory circuit from the EconoReset series by Analog Devices Inc./Maxim Integrated. It monitors a single input voltage with a threshold of 4.125 V and an overvoltage threshold of 4.24 V. The device operates within a supply range up to 5.5 V, drawing 50 uA. It features a reset delay time of 350 ms and maintains accuracy within 15%. Designed for surface mount installation in SOT-223 packages, it supports active low, open drain, or push-pull outputs. The component functions across temperatures from -40°C to +85°C.
