The MCP120-460GI/TO is a voltage supervisory device designed to hold a microcontroller in reset until the system voltage reaches a stable level. This device features a precise voltage trip point (VTRIP) range of 4.35V to 4.60V, making it ideal for monitoring 5V systems. It has an open-drain, active-low RESET output that asserts whenever the VDD pin voltage is below the trip-point, and typically holds the RESET signal for 350 ms after the voltage stabilizes. Operating over an industrial temperature range of -40°C to +85°C, this device is supplied in a TO-92 package. It provides essential protection from brown-out conditions and ensures reliable microcontroller operation during power-up and power-loss events.
