The Microchip Technology Inc. MCP120/130 is a voltage supervisory device designed to keep a microcontroller in reset until the system voltage has reached the proper level and stabilized. It also operates as protection from brown-out conditions when the supply voltage drops below a safe operating level. It features precision monitoring of 3V, 3.3V, and 5V systems, with seven voltage trip points available. This device is ideal for applications requiring reliable microcontroller operation and protection against power fluctuations.
