DESCRIPTION

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.

FEATURES

• Holds microcontroller in reset until supply voltage

reaches stable operating level

• Resets microcontroller during power loss

• Precision monitoring of 3V, 3.3V and 5V systems

• 7 voltage trip points available
