MCP120 datasheet

Description :

The Microchip Technology Inc. MCP120 / MCP130 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.


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

• Active low RESET pin

• Open drain output

• Internal pull-up resistor (5 kΩ) for MCP130

• Holds RESET for 350 ms (typical)

• RESET to VCC = 1.0V
