DS1811R-10+T&R Description

Short technical summary and product information.

The DS1811R-10+T&R is a supervisor integrated circuit designed by Analog Devices Inc. This component is part of the EconoReset family, specifically the DS1811 series, and is housed in a space-saving SOT-23-3 package.

Key features include an open-drain output with an internal 5.5 kΩ pull-up resistor, making it suitable for power monitoring applications. It automatically restarts a microprocessor after a power failure and maintains the reset signal for approximately 150 ms after VCC returns to an in-tolerance condition, allowing for system stabilization. The device operates with a supply voltage range of 0.0V to 5.5V and has a typical operating current of 40µA.

The DS1811R-10+T&R is designed to detect out-of-tolerance power supply conditions and warn a processor-based system of impending power failure. Its precision temperature-compensated voltage reference and comparator circuit ensure reliable operation.

This supervisor is available in a SOT-23-3 surface-mount package, reducing the need for discrete components in designs. The operating temperature range is -40°C to +85°C.
