The F75293 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 F75293 can support most of the USB Battery Charging Specification world-wide including BC1.2, Hisillicon FCP (Fast Charging Protocol). Apple® charging spec (for i-Pad & i-Phone) and spec 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 F75293 also supports USB high-voltage dedicated charging port (HVDCP) interface IC for the Qualcomm Quick ChargeTM 2.0 specification, and also compatible with Qualcomm® Quick ChargeTM 3.0 Specification. Quick Charge 3.0 employs Intelligent Negotiation for Optimum Voltage (INOV), an algorithm which allows your portable device to determine what power level to request at any point in time, enabling optimum power transfer while maximizing efficiency. It also supports wider voltage options, allowing a mobile device to dynamically adjust to the ideal voltage level supported by that specific device. Specifically, Quick Charge 3.0 offers a more granular range of voltages: 200mV increments, from 3.6V to 20V. That way your phone can target one of dozens of power levels. The F75293 supports the full output voltage range of either Class A or Class B. The F75293 automatically detects whether a connected Powered Device is QC 3.0/2.0 capable before enabling output voltage adjustment. If a Powered Device not compliant to QC 3.0/2.0 is detected the F75293 disable the output voltage adjustment to ensure the safe operation with legacy 5V. The F75293 supports over voltage protection (OVP) and internal discharge function. When the output voltage exceeds 20% tolerance of the requested voltage after 40μs or the discharge function is failed, the FAULT# pin will show the pull down signal for shutting down the external power IC. HVEN pin can disable high voltage such as QC2.0/3.0. The user could light up LED for high voltage protocol such as QC2.0/3.0 and could also change QC Class A or Class B via pin 2 HV_ST#. |
The F75293 is suitable for all charger products with USB interface. It provides enhanced ESD protection on the DP and DM with the MSOP10 package. It requires minimum external components, which can reduce develop & production cost dramatically.
