19 Description
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.
