DS1232N

Supervisors Overview

The DS1232N+ is a MicroMonitor supervisory circuit manufactured by Analog Devices / Maxim Integrated. It operates within a supply voltage range of 3.3 V to 5.5 V, with a maximum power supply voltage of 5.5 V and an overvoltage threshold of 5.5 V. The device features a reset delay time of 610 ms and a watchdog timer. It has a single monitored input and offers active high, active low, open drain, and push-pull output types. The quiescent current is 500 uA, with an accuracy of 10%. It supports through-hole installation in a PDIP-8 package and functions within a temperature range of -40 C to +85 C.
