Description
The DS1232+ is a Supervisor Integrated Circuit (IC) designed by Analog Devices. It's an open-drain, push-pull IC that monitors the power supply of a microprocessor and takes control to prevent damage from out-of-control or faulty operation. The IC can halt and restart the microprocessor during power transients, automatically restarting it after a power failure. Additionally, it features a pushbutton override for external control and accurate monitoring of the microprocessor's power supply (5% or 10%). This IC eliminates the need for discrete components and is available in a space-saving 8-pin mini-DIP package with an optional 16-pin SOIC surface mount package. The industrial temperature range (-40°C to +85°C) makes it suitable for various applications.
