Digital Supervisor
for Use with VI Chip BCM®



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 BCM Bus
Converter Modules over isolated UART interfaces.
Through the D44TL1A0, the host processor can
configure, set protection limits, and monitor each


Input Voltage   2.7 – 16 V
Host Interface   PMBusTM Compatible
Dimensions   LGA SiP: 10 x 10 x 2.56 mm
