Page 10: Chapter 1. Overview
EVB-USB5744 platform also supports battery charging on all four downstream ports (maximum of 5A at any one time). The EVB-USB5744 is configured for operation through internal default settings and supports custom configurations through SMBus or through the external 64-Mbit SPI Flash device, U8. -
Page 11: Chapter 2. Getting Started
USER’S GUIDE Chapter 2. Getting Started The Microchip EVB-USB5744 is designed for flexible configuration solutions. It can be configured via default internal register settings, downloadable external firmware to an onboard SPI Flash, through SMBus, or through the onboard configuration switches. -
Page 12: Smbus
When the USB5744 does not detect a valid SPI Flash image or SMBus configuration upon power-up, the EVB-USB5744 uses internal default register settings. It also sets the Vendor ID, Product ID, Language ID, and Device ID, and additional settings from internal ROM code. -
Page 13: Port Power Options: Port Enable And Port Disable Select
2.1.5 Port Power Options: Port Enable and Port Disable Select Any downstream facing port on the EVB-USB5744 can be disabled if desired. When both DP & DM signals are pulled up to +3.3V, by default the USB5744 automatically disables the port, reports the corrected number of available ports to the host, and drives the PRT_CTRL line for the disabled port(s) low. -
Page 14: Power Source - Self-Powered
2-3, 5-6 = Port Disabled POWER SOURCE - SELF-POWERED The EVB-USB5744 only supports self-powered operation, and is powered through one +12.0 V regulated 'wall wart' external power supply. The power supply plugs into the 2.5 mm connector J9 on the board. Alternatively, an external voltage can be injected onto the J6 Ext. 12 V header, which is not populated by default. -
