DS1810-5+T&R

Supervisors Overview

The DS1810-5+T&R is a supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand, designed for monitoring power supply voltages in electronic systems. It operates within a supply voltage range up to 5.5 V and features a threshold voltage of 4.62 V. The device provides a push-pull output type with an active low reset signal and includes a minimum reset delay time of 100 ms. It supports manual reset functionality and incorporates a watchdog timer for system reliability. The component is housed in a SOT-23-3 package and functions across a temperature range from -40°C to +85°C.

Supervisors Feature Summary
