The DS1816R-5/TR, manufactured by Maxim Integrated (formerly Dallas Semiconductor), is a 3.3V EconoReset supervisor designed to monitor power supply status. It automatically restarts a microprocessor after a power failure and ensures a stable reset signal for approximately 150ms after VCC returns to an in-tolerance condition, allowing the system to stabilize.
Key features include a precision temperature-compensated voltage reference and comparator circuit. The device offers accurate power monitoring with a VCC trip point typically at 3.06V, with options for 5%, 10%, or 20% tolerance. It operates over a wide temperature range of -40°C to +85°C.
The DS1816R-5/TR is available in both TO-92 and space-saving SOT-23 surface-mount packages. It features an efficient open-drain output with an internal 5kΩ pull-up resistor, reducing the need for discrete components in power monitoring and reset circuitry.
This supervisor is ideal for applications requiring reliable power-fail detection and microprocessor reset management, ensuring system integrity during power fluctuations.
