DS1836A-10

Supervisors Overview

The DS1836A-10 is a MicroManager supervisory circuit designed for monitoring power supply voltages in microprocessor systems. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 4.37 V for undervoltage detection. The device provides a reset delay time of 500 ms and includes battery backup switching capabilities. It is available in an 8-SOIC surface-mount package and supports CMOS or open-drain output configurations.
