The Microchip Technology Inc. MCP120/130 is a volt-age supervisory device designed to keep a micro controller 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. Both devices are available with a choice of seven different trip voltage sand both have open drain outputs. The MCP130 has an internal 5 k\Omega pull up resistor. Both devices have active low RESET pins. The MCP120/130 will assert the RESET signal whenever the voltage on the VDD pin is below the trip-point voltage.
