DS1816R-10-U+ Description

Short technical summary and product information.

The DS1816R-10-U+ from Analog Devices is an EconoReset supervisor designed to monitor power supply status and automatically restart a microprocessor following a power failure. It maintains a reset signal for approximately 150ms after VCC returns to an in-tolerance condition, allowing the power supply and processor to stabilize.

 

This supervisor features a precision temperature-compensated voltage reference and comparator circuit. It offers accurate power monitoring with a 3.3V threshold and an open-drain output with an internal 5k pull-up resistor. The operating temperature range is -40°C to +85°C.

 

Available in a space-saving SOT-23-3 package, the DS1816R-10-U+ reduces the need for discrete components in system designs. Its surface mount capability makes it suitable for various electronic applications requiring reliable power monitoring and reset functions.

 

Key electrical characteristics include a supply voltage range of 0V to 5.5V and a typical operating current of 35µA. The reset timeout is a minimum of 100ms, ensuring proper system stabilization.
