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, an open drain output, and a temperature range from -40°C to +85°C. This device is ideal for applications requiring reliable microcontroller reset and brown-out protection.
