The BCM in a VIA package provides accurate telemetry monitoring and reporting, threshold and warning limits adjustment, in
addition to corresponding status flags.
The BCM’s internal µC is referenced to low voltage side signal ground.
The BCM provides the host system µC with access to standalone BCM. The standalone BCM is constantly polled for status by the
internal µC. Direct communication to BCM is enabled by a page command. For example, the page (0x00) prior to a telemetry inquiry
points to the internal µC data and pages (0x01) prior to a telemetry inquiry points to the BCM connected data. The BCM constantly
polls it’s data through the PMBus.
The BCM enables the PMBus compatible host interface with an operating bus speed of up to 400kHz. The BCM follows the PMBus
command structure and specification.
