1.1.1. Programmable Power Management Controller (PPMC)

Using a programmable power management controller provides a full-featured option to implement the power sequencing requirements.

These controllers provide the necessary power-up/down sequence control functions. These controllers can dynamically monitor and scale the regulator's output voltage, and supervise fault conditions such as over voltage or under voltage. To program the power management controller, typically a PMBus or I2C interface is used to connect to an intelligent host such as the system's microprocessor.

PPMC can be an optimal solution for systems in which up-time and fault tolerance are critical features and voltage monitoring and fault reporting are essential system requirements.
