D44TL1A0 Vicor

Digital Supervisor D44TL1A0 for use with VI Chip BCM Bus Converter Module Features & Benefits Product Description The D44TL1A0 is a digital power system supervisor which PMBus compatible host interface for enhanced provides a communication interface between a host processor monitoring and control of ChiP BCM Bus and up to four ChiP BCM Bus Converter Modules. The Supervisor Converter Modules communicates with a system controller via a PMBus compatible Interfaces with up to four BCMs through dedicated UART interface. Acting as a communication bridge, the Supervisor communicates with up to four BCM Bus Converter Modules interfaces via Vicor Digital Isolators I13TL1A0 enabling over isolated UART interfaces. Through the D44TL1A0, the host secondary referenced BCM control and telemetry processor can configure, set protection limits, and monitor OVP, OCP, OTP protection and monitoring each BCM. 10mm x 10mm Land Grid Array (LGA) package Standard Models Typical Applications 380V Power Distribution DC Part Number Package Type Temperature High End Computing Systems D44TL1A0 LGA (10 x 10mm) T-Grade (-40C to 125C) Automated Test Equipment Industrial Systems High Density Power Supplies Communications Systems Transportation BCM Digital Supervisor Rev 1.5 Page 1 of 25 08/2020D44TL1A0 Typical Application NC NC SGND SADDR NC NC SDA NC NC TX1 SCL TX2 BCM Digital Supervisor Rev 1.5 Page 2 of 25 08/2020 Isolation Barrier ChiP BCM 4 ChiP BCM 3 ChiP BCM 2 ChiP BCM 1 +IN +OUT Internal Bias + 1.5 k 1.5 k LOAD SER-OUT VIN EN C SER-IN - -IN -OUT 3.3V, at least 20mA Digital Isolator EN Control EN Ctrl4 EN Ctrl3 Ref to Digital Isolator datasheet EN Ctrl2 EN Ctrl1 BCM EN PRI-OUT-A SEC-IN-A for more details TX4 TX3 SER-IN TX1 TX2 TX1 PRI-OUT-B SEC-IN-B RX4 RX3 RX2 SER-OUT RX1 Host SDA PRI-IN-C SEC-OUT-C SEC-COM4 SEC-COM3 SEC-COM2 SEC-COM1 c PRI-COM SEC-COM SCL SCL SGND PMBus 3 k 3 k 5V EXT RX4 VDDB VDD RX3 VDD CP VCC RX2 NC D SD D RX1 NC D44TL1A0 Q RD TX4 NC Flip-flop SGND Q TX3 SSTOP 74LVC1G74DC R1 R2 SGND SDA
