DS1236S-10+T&R

Supervisors Overview

The DS1236S-10+T&R is a MicroManager supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 4.5 V to 5.5 V and features a threshold voltage between 4.5 V and 5.5 V. The device monitors one input and provides active high and active low outputs with a reset delay time of 150 ms. It includes a manual reset function, a watchdog timer, and battery backup switching capabilities. Power failure detection is supported, and the chip enable signal allows for control. The operating power supply current is 4 mA, with an overvoltage threshold of 4.5 V and an undervoltage threshold of 4.25 V. It functions in temperatures from -40°C to +85°C.
