DESCRIPTION

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.
