In the event that a core processor fails in your circuit, the MCP131T-195I/TT processor from Microchip Technology supervisory ensures that there is a backup to take over. It has a typical reset threshold voltage of 1.9 V, with a minimum of 1.872 V and a maximum of 1.929 V. This device has a minimum operating supply voltage of 1 V and a maximum of 5.5 V. This part has a minimum operating temperature of -40 °C and a maximum of 125 °C.
The MCP131T-315E/TT is a MicroPower Voltage Supervisor with active-low open-drain output and internal pull-up resistor. It is designed to keep a microcontroller in reset until the system voltage has reached and stabilized at the proper level for reliable system operation.
