7.2.4.2

Constant Current Limiting (Variable Slope)

Constant current limiting is used when a portable device handshakes using the BC1.2 DCP charger

emulation profile and the current drawn is greater than ILIM (and ILIM < 1.5 A). It’s also used in BC1.2

CDP mode and during the DCE Cycle when a charger emulation profile is being appliedand the

emulation timeout is active.

In CC mode, the port power switch allows the attached portable device to reduce VBUS output voltage

to less than the input VS voltage while maintaining current delivery. The V/I slope depends on the user

set ILIM value. This slope is held constant for a given ILIM value.
