The MPC18730EP offers a flexible power solution that can be tailored to the most demanding system requirements. It can be used to provide a failsafe power supply monitor and system reset control, intelligent power control, load switching and power sequencing support, voltage tracking, and power supply fault detection. This PMIC can be applied in a wide range of consumer, industrial and network applications such as lighting controllers, illumination systems, image processing systems and industrial controllers.

Working Principle

Power distribution within a system is a critical component in the overall performance. The MPC18730EP is designed to provide an efficient, cost-effective and highly integrated solution for power and voltage management, allowing each component to operate at the optimum voltage level. The integrated circuit is a complete power supply monitor and system reset control, including automatic power-on and power-off, sequencing and sequencing timing, voltage monitoring, under voltage lockout and over voltage detection.

The MPC18730EP is designed to sequence the supply rails in a correct order when powering up the system. It makes sure that each power rail is started in the correct sequence, and all other necessary power rails have been enabled before enabling a new one. This increase system reliability by ensuring that no component is exposed to an unregulated voltage state. The circuit also features an adjustable voltage tracking mechanism to ensure that the correct voltage is applied to each device.

The MPC18730EP is programmed via an I2C interface, allowing for easy adjustment of voltage, power sequence, timing, and other settings. It also contains a watchdog to protect against unexpected system failure. The integrated circuit supports a two-set power-on reset and four-phase power-down reset, providing reliable system reset with low current consumption. The MPC18730EP also includes two pulse-width modulation (PWM) outputs to support fan speed control.

Conclusion

The MPC18730EP is an ideal solution for a wide range of consumer, industrial and network applications such as lighting controllers, illumination systems, image processing systems and industrial controllers. The integrated circuit combines efficiency, flexibility, reliability and compatibility in a single package. It provides a failsafe power supply monitor and system reset control, intelligent power control, load switching and power sequencing support, voltage tracking, and power supply fault detection. Furthermore, it is easy to program, allowing for fine-tuning of voltage, power sequence, and timing.
