DESCRIPTION

RST

The Microchip Technology Inc. MCP120/130 is a volt-

age supervisory device designed to keep a microcon-

troller in reset until the system voltage has reached the

proper level and stabilized. It also operates as protec-

tion 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.
