4. Disconnect the portable device from the EVB.

5. The UCS1002 should detect a removal, switch to the Detect power state, and stop delivering a

charge.

shows the GUI after a removal was detected.

7.2

Charging Downstream Port (CDP)

The CDP charging profile is based on the Battery Charging standard 1.x. When a BC1.x compliant
portable device attachment is detected, the UCS1002 and the portable device do handshaking based
on the standard. If handshaking is successful, charging occurs up to the set current limit.

To select the CDP port power profile, M1, M2, and EM_EN must all be high. This can be done by
removing the jumpers for these pins (J7, J8, and J6 respectively) or by using the pin override in the
GUI (see

Section 6.2.3, "Pin Override"

).
