PMIC supervisors are an invaluable piece of technology that allows engineers to use microcontrollers in a wide variety of applications. XC6122D340ER-G is one such supervisor. It utilizes a supervisor circuit to monitor multiple inputs and provide feedback to a microcontroller that can then adjust its operation accordingly. This feedback system allows microcontrollers to quickly detect any dangerous voltage levels or changes in current and quickly shut them down, ensuring maximum power efficiency, reliability, and excellent performance.

The XC6122D340ER-G is uniquely designed to manage up to four voltage inputs, along with a digital output system. This digital output system plugs into the supervisor circuit’s supervisor out pin and directly drives the microcontroller reset pin. This ensures that the microcontroller can detect a drop in input voltage causing a reset even after the voltage has dropped and stabilized.

The supervisor circuit can be configured to monitor one or two of the supply voltage inputs and includes a trigger reset feature that requires two simultaneous trigger events in order to reset the microcontroller. The supervisor also offers two disable conditions, a power-on reset and current low reset, both of which can be configured to trigger the reset at the closest voltage above the programmed trigger voltage level.

The supervisor circuit offers a Fail-safe Shutdown feature that helps to protect the microcontroller and other components connected to the system, like LEDs, valves, and sensors. This feature triggers when a voltage above the set threshold is detected, immediately shutting down the microcontroller. This safety feature helps to prevent potentially dangerous overvoltage conditions from occurring.

The XC6122D340ER-G supervisor also offers a Watchdog Timer feature which can be programmed to monitor and reset the microcontroller clock if the microcontroller has stopped responding. This offers an additional level of protection against microcontroller malfunctions, helping to keep systems working properly.

The XC6122D340ER-G supervisor is a powerful and flexible tool that can help engineers scale the power and performance of their designs. Its advanced features make it a great choice for applications where safety and reliability are a priority.
