Page 2: Introduction
The USB007A series dongle is a PC-USB COM port to PMBus bridge dongle that allows access to the XDP710 registers from the PC software configurator. This user guide describes how to set up the evaluation board and configure the internal registers to evaluate the performance of XDP710-002 to limit inrush current (regulation on programmed FET SOA) during startup, telemetry and fault control. -

• XDP710 powers up as soon as VDD_VIN is equal to or greater than 5.5 V. At this point, communication and programming is possible, but the FET will still be off. To turn on the FET, a minimum of 9 V is required, then the following registers must be programmed at a minimum to turn on the device: •... -

PCBA XDP710 evaluation user guide Programming, setup, and turn-on instructions 4.1.9 Program VIN_OV_FAULT_LIMIT If using AADM or ACM, this step can be skipped, as the input overvoltage (OV) fault limit is set by external resistors on the OV pin. In DCM, program the desired OV fault limit in the VIN_OV_FAULT_LIMIT register (0x55). If OV fault is not used, the register can be programmed to 88 V, or the fault can be disabled. -
Page 27: Xdp710 Programming Under Different Modes
XDP710 programming under different modes There are two different modes in which the XDP710 can be operated, namely FDM and AADM. FDM has two selections: DCM and ACM. AADM or FDM can be selected based on the resistor connected on the Mode 0 and Mode 1 pins on the evaluation board. -
