J11, J12 Signal Ground These test points connect to the signal ground of the board. These are the ground reference for the UCS81003. J13, J14, J15 Earth Ground These test points connect to the earth ground of the board (the shield of the USB connectors). -
Page 19: Software Installation
Installation and Operation SOFTWARE INSTALLATION To begin using the UCS81003 Evaluation Board, software must be installed on a ® Windows -based computer with a USB port. 1. Download the software archive from the board’s web page, unzip it and double-click the Setup.exe, to start the installation. - Page 20 When installation is complete, the program will automatically run. If a screen appears requiring a restart for the changes to take effect, reboot the computer. The UCS81003 interface will start with the SMBus communications. 2014 Microchip Technology Inc.

To view this behavior, perform the following: 1. Connect V to the evaluation board (see Section 2.4 “Jumpers on the... - Page 30 FIGURE 4-7: Main Tab - Charging Started. 4. Disconnect the portable device from the board. The UCS81003 should detect a removal, switch to the Detect power state, and stop delivering a charge. Figure 4-8 shows the interface after a removal was detected.

CHARGING DOWNSTREAM PORT (CDP) The CDP charging profile is based on the “USB Battery Charging Specification v1.x”. When a BC1.x-compliant portable device attachment is detected, the UCS81003 and the portable device do handshaking based on the standard. If handshaking is successful, charging occurs up to the set current limit. - Page 32 UCS81003 Evaluation Board User’s Guide As shown in Figure 4-10, the green trace is the instantaneous current, while Note: the red diagonal line is the charge being delivered in mAh. Both are also presented in numeric format in the bottom left boxes. Trace color and characteristics can be changed by clicking on the waveform boxes to the left of these numerical values.
