Complete System PMIC, Featuring 13 Regulators, 8 GPIOs, RTC, and Flexible Power Sequencing for Multicore Applications

Total Power Management IC (PMIC) for Computationally Intensive for Mobile Platforms Using SoC Application Processors

Please check latest availability status for a specific part variant.


The MAX77863 is a complete power management IC (PMIC) for mobile devices using multicore application processors.

It is available in a wafter-level package (WLP) to be used in space-constrained applications.

The IC offers a total of 13 regulators. Two regulators have differential remote sensing and are rated for both continuous and peak output current.

Numerous factory-programmable options allow the IC to be tailored for many applications. Contact the factory for more information about programmable options; minimum order quantities may apply.
