The F75299 is low-cost USB Dedicated Charger Identification Circuit IC which is so smart to recognize most of the mainstream handheld devices.  It allows devices to draw current as much as using as the original adapter. The F75299 can support most of the USB Battery Charging Specification world-wide including BC 1.2, Apple^® charging spec (for i-Pad & i-Phones) and specs for Samsung Galaxy Tab. Apple Inc. has upgraded its charger output capacity for tablets to 12W output (maximum 2.4A @ 5V). By setting the USB data pins (D+/D-) to the required voltage levels, the charging devices will recognize their required voltage levels, and starts to draw the suitable current to charge.

The F75299 also supports USB high-voltage dedicated charging port (HVDCP) interface IC for the Qualcomm^® Quick Charge^TM 2.0 (QC 2.0) specification. The F75299 supports the full output voltage range of either Class A or Class B. Optionally 20V can be inhibited for protecting the battery charger from the accidental damage. The F75299 automatically detects whether a connected Powered Device (PD) is Quick Charge^TM 2.0 capable before enabling output voltage adjustment. If a PD which is not compliant to Quick Charge^TM 2.0 is detected the F75299 disable output voltage adjustment to ensure the safe operation with legacy 5 V only USB PDs.   

The F75299 has a selection pin to select Apple 2.1A or 2.4A mode and also built in with EN pin for disabling Fintek old USB Charging ID IC F75198 function. F75198 supports all of the functions same as F75299 except QC 2.0 function.

The F75299 is suitable for all charger products with USB interface. It provides enhanced ESD protection up to ±8kV on the DP and DM with the MSOP10 package. It requires minimum external circuits, which can reduce develop & production cost dramatically.
