The MCP121T-315E/TT from Microchip Technology is a micropower voltage supervisor designed to ensure reliable system operation by keeping microcontrollers in reset until system voltage stabilizes.
This device monitors a single voltage level, specifically set at 3.08V. It provides an active-low reset output with an open-drain or open-collector configuration, suitable for various system designs. The supervisor operates with an ultra-low supply current of 1.75 µA in steady-state conditions, making it ideal for battery-powered equipment.
Key features include a typical reset delay of 120 ms and a minimum reset timeout of 80 ms. The operating temperature range is -40°C to 125°C (TA). The MCP121T-315E/TT is available in a compact SOT-23-3 surface-mount package, compatible with TO-236-3 and SC-59 footprints.
Applications for this voltage supervisor include critical microcontroller and microprocessor power-monitoring in computers, intelligent instruments, and portable battery-powered devices.
