DESCRIPTION
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 k
low RESET pins. The MCP120/130 will assert the
RESET signal whenever the voltage on the V
below the trip-point voltage.
