DS1815R-20 Description

Short technical summary and product information.

The DS1815R-20 is an EconoReset supervisor IC manufactured by Analog Devices / Maxim Integrated. It is designed to automatically restart a microprocessor after a power failure and maintains the reset signal for approximately 150ms after VCC returns to an in-tolerance condition, allowing power supply and processor stabilization.

 

This device operates within a supply voltage range of 0V to 5.5V and features a voltage threshold of 2.55V. The reset output is active low and has a timeout of 100ms minimum. It monitors a single voltage and provides a push-pull, totem pole output.

 

The DS1815R-20 is available in a surface mount SOT-23-3 package, specifically TO-236-3, SC-59, SOT-23-3. It operates across a wide temperature range of -40°C to 85°C.

 

This component reduces the need for discrete components in power monitoring applications, making it suitable for systems requiring reliable power-fail detection and processor reset.
