Revision 1.4 (07-16-13)

DATASHEET

4. If the portable device does not draw more than IBUS_CHG current when tEM_TIMEOUT timer expires,

the UCS1002 will stop the Legacy 7 charger emulation profile. This will cause the voltage put onto

the DPOUT pin to be removed. Emulation reset occurs, and the UCS1002 will initiate the next

charger emulation profile.

Custom Charger Emulation Profile

The UCS1002 allows the user to create a Custom charger emulation profile to handshake as any type

of charger. This profile can be included in the DCE Cycle. In addition, it can be placed first or last in

the profile sequence in the DCE Cycle. See Section 10.13.1, "Custom Emulation Configuration - 40h".

The Custom charger emulation profile uses a number of registers to define stimuli and behaviors. The

Custom charger emulation profile uses three separate stimulus / response pairs that will be detected

and applied in sequence, allowing flexibility to “build” any of the preloaded emulation profiles or tailor

the profile to match a specific charger application.

For details, see application note 24.14 “UCS1002 Fundamentals of Custom Charger Emulation.
