The D44TL1A0 is a digital power-system supervisor which provides a communication interface between a host processor and up to four ChiP™ BCMs^® (Bus Converter Modules). The supervisor communicates with a system controller via a PMBus^®-compatible interface. Acting as a communication bridge, the supervisor communicates with up to four BCMs over isolated UART interfaces. Through the D44TL1A0, the host processor can configure, set protection limits and monitor each BCM.
