PRODUCTION DATA
The TPS25860-Q1 device integrates an auto-detect state machine that supports all the DCP charging schemes as shown in Figure 10-25. The auto-detect state machine starts in the Divider3 scheme. If a BC1.2 or YD/T 1591-2009 compliant device is attached, the TPS25860-Q1 device responds by turning the power switch back on without output discharge and operating in 1.2-V mode briefly before entering BC1.2 DCP mode. Then, the auto-detect state machine stays in that mode until the device releases the data line, in which case, the auto-detect state machine goes back to the Divider 3 scheme. When a Divider 3-compliant device is attached, the TPS25860-Q1 device stays in the Divider 3 state.
