The MCP120T-450I/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
