Technical guide for interfacing the NXP MC13783 PMIC with i.MX31 processors to manage power gating, dynamic voltage scaling, and battery charging in portable electronics.
This application note details the implementation of power management systems using the NXP MC13783 PMIC and i.MX31 applications processors. It explains how to utilize advanced power-saving features including Dynamic Process Temperature Compensation (DPTC), Dynamic Voltage and Frequency Scaling (DVFS), and power gating to extend battery life. The document provides a technical overview of the MC13783 power tree, including its programmable buck and boost regulators, LDOs, and battery charging circuits. It also outlines the interconnection and control logic required for system resets, power sequencing, and SPI communication between the processor and the PMIC for optimized performance in 3G mobile devices and portable media players.

NXP
However, the MC13783 is protocol independent, and many of the core functions and peripheral supplies are equally well suited to non-phone applications built with the MC13783 and i.MX (MCIMX31) application processor lineup.
