FM5887C-FM5888C
FM5887C and FM5888C are USB dedicated charging port controllers. The automatic detection feature monitors the USB data line voltage and automatically provides the correct electrical characteristics on the data line to charge compatible devices in the following dedicated charging system configurations:
1. Voltage divider DCP is required to apply 2.7V and 2.7V voltage on the D+ and D- lines, respectively
2. BC1.2 DCP is required to short-circuit line D+ to line D-
3. China Telecom standard YD/T 1591-2009 short-circuit mode, is required to short-circuit D+ line to D- line
