Description:
The Microchip Technology Inc. MCP120 / MPC130 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
• Active low RESET pin
• Open drain output
• Internal pull-up resistor (5 kΩ) for MCP130
