Dedicated Charger Emulation (DCE) Cycle
As shipped, the UCS1002 is ready to function as a dedicated charger, which will be applied when there
is an attach detection. To view this behavior, perform the following:
1. Connect VS to the EVB (see
Section 3.6, "Jumper Settings"
). The VS Low indicator on the Main
Tab must be dark. If the VS Low indicator is red, the voltage is not high enough to charge a portable
device.
2. Connect a portable device to the EVB. Use the OEM USB charging cable that came with the
portable device.
3. The UCS1002 should detect an attachment, switch to the Active power state, apply an emulation
profile, and deliver a charge.
