The MCP120T-475I/TT is a Supervisor Circuit with active-low open-drain output. The 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. It will assert the RESET signal whenever the voltage on the VDD pin is below the trip-point voltage.

• Holds microcontroller in reset until supply voltage reaches stable operating level
• Resets microcontroller during power loss
• RESET to VCC=1V
• Accuracy of ±125mV for 5V systems and ±75mV for 3V systems over-temperature
• 45µA Typical operating current
