Microchip Technology, Inc. Supervisors MCP130-300I/SN

The Microchip MCP130 is a voltage supervisory circuit designed to ensure that a microcontroller remains in reset until the supply voltage stabilizes at a safe operating level. It features an active low RESET pin with an open drain output and includes an internal pull-up resistor of 5 k,Ѷ. The device supports a wide operating voltage range from 1.0V to 5.5V and offers seven selectable voltage trip points for precise monitoring of 3V, 3.3V, and 5V systems. Typical operating current is 45 µA, and it provides a reset hold time of approximately 350 ms when the voltage drops below the trip point. The MCP130 operates within an industrial temperature range of -40°C to +85°C and has an accuracy of ±125 mV for 5V systems and ±75 mV for 3V systems over temperature. This device is suitable for applications requiring reliable voltage monitoring and reset functionality in microcontroller-based designs.
