The DS1811R-10+TR from Maxim Integrated (MAX) is a supervisor IC that provides essential power monitoring functions for microprocessor-based systems. It utilizes a precision temperature-compensated voltage reference and comparator circuit to detect out-of-tolerance power supply conditions.
When VCC drops below a specified threshold, the device asserts an active-low reset signal. Upon restoration of VCC to an in-tolerance condition, the reset signal is maintained for approximately 150 ms, allowing the power supply and processor to stabilize before releasing the reset.
This supervisor IC is available in a space-saving SOT-23-3 package, making it suitable for applications where board space is limited. It features an open-drain output with an internal 5.5 kΩ pull-up resistor. The operating temperature range is -40°C to +85°C, ensuring reliable performance in various environments.
Key features include automatic microprocessor restart after power failure, a reset hold time of 150 ms, and reduced need for discrete components. The DS1811R-10+TR is designed to simplify power supply monitoring and enhance system reliability.
