title: MCP16502 - High-Performance PMIC
maintainers:
- Andrei Simion <andrei.simion@microchip.com>
description:
The MCP16502 is an optimally integrated PMIC compatible
with Microchip's eMPUs(Embedded Microprocessor Units),
requiring Dynamic Voltage Scaling (DVS) with the use
of High-Performance mode (HPM).

description: GPIO for LPM pin.
Note that this GPIO must remain high during
suspend-to-ram, keeping the PMIC into HIBERNATE mode.
