| 13 | The MAX20086-MAX20089 are dual/quad camera power protectors, designed to |
| 14 | deliver power over coax for radar and camera modules. They support |
| 15 | software-configurable output switching and monitoring. The output voltage and |
| 16 | current limit are fixed by the hardware design. |
