The DS1811R-5/TR is a 5V EconoReset supervisor from Dallas Semiconductor, featuring an open-drain output and an internal 5.5 kΩ pull-up resistor. This component is designed to monitor power supply status and automatically restart a microprocessor following a power failure.
Key electrical specifications include an operating temperature range of -40°C to +85°C and a supply voltage range of 0V to 5.5V. The device maintains a reset signal for approximately 150 ms after VCC returns to an in-tolerance condition, allowing for system stabilization. It offers various VCC trip points depending on the specific variant, with the DS1811-5 having a typical trip point of 4.62V.
Available in both TO-92 and SOT-23 packages, the DS1811R-5/TR is suitable for various board space requirements. Its through-hole mounting type (for TO-92) and surface-mount capability (for SOT-23) offer flexibility in design implementation. The device reduces the need for discrete components in power monitoring circuits.
