title: Maxim Integrated MAX20086-MAX20089 Camera Power Protector

maintainers:
  - Laurent Pinchart <laurent.pinchart@ideasonboard.com>

description: |
  The MAX20086-MAX20089 are dual/quad camera power protectors, designed to
  deliver power over coax for radar and camera modules. They support
  software-configurable output switching and monitoring. The output voltage and
  current limit are fixed by the hardware design.
