The MCP121T-195I/TT from Microchip Technology is a voltage supervisor designed for critical microcontroller power-monitoring applications. It ensures a microcontroller remains in reset until the system voltage stabilizes at a proper operating level.
This device features a precise 1.9V voltage threshold and an active-low, open-drain reset output. It includes a reset timeout of 80ms minimum. The supervisor operates with ultra-low supply current, making it suitable for battery-powered equipment.
Available in a compact SOT-23-3 surface-mount package, the MCP121T-195I/TT is designed for industrial temperature ranges from -40°C to 85°C. Its robust design and essential monitoring capabilities make it a reliable choice for embedded systems requiring stable power-on sequencing.
Applications include computers, intelligent instruments, and portable battery-powered devices where maintaining system integrity during power fluctuations is crucial.
