Chapter 1. Overview
1.1 INTRODUCTION
The EVB-USB5744 Revision A is a demonstration and evaluation platform that provides the
necessary requirements and interface options for evaluating the USB5744 Ultra Fast four port
battery charging hub on a 4-layer RoHS-compliant Printed Circuit Board (PCB). This will allow
the user to gain an understanding of the product and accelerate the integration of the
EVB-USB5744 into the user’s design. The EVB-USB5744 is compliant with the USB 3.0 USB
Specification and supports SuperSpeed (SS), High-Speed (HS), Full-Speed (FS), and
Low-Speed (LS) USB signaling for complete coverage of all defined USB operation speeds. The
evaluation platform supports four downstream ports that are USB 2.0 and USB 3.0 compliant.
The EVB-USB5744 platform also supports battery charging on all four downstream ports (maxi-
mum 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. The EVB-USB5744 demonstrates driver compatibility with Micro-
soft® Windows® 8x, Windows 7, Windows XP, Mac OS® X 10.4+, and Linux® hub drivers.
The EVB-USB5744 provides the following features:
• USB5744 in a 56-pin QFN RoHS compliant package
• USB 3.0 compliant (SS, HS, FS, and LS operation)
• USB pins are 5 V tolerant
• Self powered operation
• Four downstream USB 2.0/3.0 ports
• All downstream ports support individual port power and overcurrent sense
• All downstream ports are battery charge enabled (2.1A max per port)
• Can support up to 5A down stream Port Power at any one time
• Onboard SPI Flash for external downloadable firmware
• Low-cost 4-layer space saving design
• Operates from a single voltage (+12.0 V, regulated) external power supply
• Onboard 25 MHz crystal or external clock input
• Single onboard +5.25 V, 6 Amp regulator
• Single onboard +3.3 V, 0.5 Amp regulator
• Single onboard +1.2 V, 1 Amp regulator
• Port Power and Port Enable LED indicators
• LED indicators for SPI/Strap Configuration
