The DS1811R-5+TR is a 5V EconoReset supervisor IC from Analog Devices / Maxim Integrated, designed to monitor power supply status and automatically restart microprocessors after power failures. It maintains the reset signal for approximately 150 ms after VCC returns to an in-tolerance condition, allowing power supply and processor stabilization.
Key electrical specifications include a supply voltage range of 0V to 5.5V. The VCC trip point for the -5 version is typically 4.62V, with a minimum of 4.50V and a maximum of 4.75V. It features an open-drain output with an internal 5.5 kΩ pull-up resistor. The operating current is typically 30 µA, with a maximum of 40 µA when VCC is below 5.5V. The output current capability is up to 10 mA at 0.4V.
This supervisor operates across a wide temperature range of -40°C to +85°C. It is available in both low-cost TO-92 and space-saving SOT-23 packages, suitable for various board space constraints. The device reduces the need for discrete components in power monitoring circuits.
