| 20 | ----------- | |
| 21 | ||
| 22 | The Vicor PLI1209BC is an isolated digital power system supervisor that provides | |
| 23 | a communication interface between a host processor and one Bus Converter Module | |
| 24 | (BCM). The PLI communicates with a system controller via a PMBus compatible | |
| 25 | interface over an isolated UART interface. Through the PLI, the host processor | |
| 26 | can configure, set protection limits, and monitor the BCM. | |
