MICROCHIP TECHNOLOGY Page 4 DT-USB5734 Quick Start Guide 2 DT-USB5734 Overview 2.1 Features USB5734 in a 64-pin QFN RoHS compliant package USB 3.0 compliant (SS, HS, FS, and LS operation) Two downstream USB-C ports, and two USB3-A ports Four downstream ports enabled for battery charging: o Two USB3-C ports – 3A maximum per port o Two USB3-A ports – 1.5A maximum per port Microchip MIC24055 based switching regulator circuit can provide up to 10A at 5V when using a 12V 60 watt minimum power supply. Up to 9A total battery charging current when using a 12V, 60 watts minimum power supply Operates from a single 12VDC external power supply USB to Serial bridge with on board RS-232 transceiver and DB9 connector TTL level serial signals available on headers for probing Port Power LED indicators Power LED indicators for on board 5V and 3.3V DC regulators.

No board switch settings or jumpers are required for normal operation 2. For installation the following items are required which are not included on the kit: a. 12VDC Power supply, minimum 30 watts. For maximum current during USB port battery charging a 12VDC 60 watt supply is recommended. b. USB3-A to USB3-B cable c. USB3-C, USB3, USB2 devices for connecting to USB downstream ports d. DB9 serial cable if using the serial port 3. Connect 12VDC supply to wall outlet and DC plug into the DT-USB5734 DC jack. 4. Connect the USB3-A plug of USB3 cable to PC and USB3-B plug to USB3-B connector on the DT-USB5734. 5. Press reset pushbutton and release, the red reset LED should turn on and off. 6. With nothing connected to the USB downstream ports only 4 LEDs should be on: a. 5V LED b. 3V3 LED c. PORT3 LED d. PORT4 LED 7. At this point the board is ready for use, connect USB devices as required. 8. If a device is connected to USB3-C port 1: a. PORT1 LED turns on b. If C_AB1n LED is off, USB-C A side is active c. If C_AB1n LED is on, USB-C B side is active 9. If a device is connected to USB3-C port 2: a. PORT2 LED turns on b. If C_AB2n LED is off, USB-C A side is active c. If C_AB2n LED is on, USB-C B side is active Serial Port The serial connector is wired as a Data Terminal Equipment (DTE). To use the serial port: 1. Connect a DB9 serial cable to UART Port connector. If connecting to a Modem or other data communications equipment (DCE) a serial straight cable is used. If connecting to a DTE or PC serial port a NULL Modem serial cable is required. 2. A terminal program such as Tera-Term or serial port application is required on the PC where the DT-USB5734 is connected. 3. The serial port from the DT-USB5734 will appear as USB5734 COM Port, see example below for Tera Term. Note that the actual port COM number will most likely be different from the one shown.
