    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. Both devices are
    available with a choice of seven different trip voltages
    and both have open drain outputs. The MCP130 has an
    internal 5 kΩ pullup 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. TO-92 with
