5 4 3 Evaluation Board for USB4624 with Battery Charging 1 Revision History Revision Date A platform that supports: D 2 USB4624 in the QFN48 package Battery Charging on two USB 2.0 ports w/ Charger Current LED display USB 2.0 HSIC on two ports Self-power from 12 VDC (Molex PC, or barrel) SMBus interface SPI programming and configuration UART bridge interface Optional 9V Auxilliary Power Out Revision Summary Author A 20121114 Released C. Johnson A1 20130612 Replaced 180uF caps on downstream VBUS with 150uF caps. J. Hancock A2 20150924 Replaced Maxim PPCs with Micrel part number. The new part caused the ILIM resistor to change as well. J. Hancock D C C B B A A Microchip Technology, Inc. USB/Networking Group - UNG www.Microchip.com Description: Evaluation Board -- USB4624 Bat.
