For use with VI Chip® BCM Bus Converter Module
Features
• PMBus™ compatible host interface for enhanced
monitoring and control of ChiP BCM
Bus Converter Modules
• Interfaces with up to four BCMs through
dedicated UART interfaces via Vicor Digital
Isolators I13TL1A0 enabling secondary
referenced BCM control and telemetry
• OVP, OCP, OTP protection and monitoring
• 10 mm x 10 mm Land Grid Array (LGA) package
Typical Applications
• 380 VDC Power Distribution
• High End Computing Systems
• Automated Test Equipment
• Industrial Systems

• Transportation
Product Description
The D44TL1A0 is a digital power system supervisor which
provides a communication interface between a host processor
and up to four ChiP BCM 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 BCM.

Signal Characteristics
Specifications apply over the rated supply range (VDD or VDDB), unless otherwise noted; Boldface specifications apply over the temperature range of -40°C
≤ TINTERNAL ≤ 125°C (T-Grade); All other specifications are at TINTERNAL = 25ºC unless otherwise noted.
VDD Pin
• Regulated supply power input to the module, required when VDDB is not used to supply power to the device.
• Regulated output 3.3 V nominal output when supervisor is powered by VDDB.
• Intended to be used as low current supply for ancillary circuits.
