If the power bank is to charge for the phone, when IP5328P enter discharge mode, it will detect the fast

charge type and request on DP, DM, which support fast charge for devices of QC2.0/QC3.0, FCP, AFC, SFCP, MTK,

and Apple 2.4A mode, Samsung 2.0A mode and BC1.2 1.0A mode.

For Apple 2.4A mode: DP=DM=2.7V

For Samsung 2.0A mode: DP=DM=1.2V

For BC1.2 1.0A mode: DP short to DM

Under BC1.2 mode, when the DP voltage is detected in the range of 2V~0.325V for 1.25s, fast charge will be

initially determined, then the short status between DP and DM will be disconnected, and DM pull-down 20kOhm

to GND at the same time. After which, if in the following 2ms the DP voltage is in range of 2V~0.325V and DM

lower than 0.325V, fast charge handshake is accomplished successfully. Then QC2.0/QC3.0 device can request for

desired voltage according to the QC standards. Any time DP lower than 0.325V will force to exit the fast charge

mode, the ouput voltage will fall back to default 5V.

QC2.0/QC3.0 output voltage request rule:

Continuous mode is supported by QC3.0, voltage can be adjusted by 0.2V/step according to QC3.0 request under

the continues mode.
