Weltrend Launches Fast Charge Interface Controller Supports Qualcomm Quick Charge 2.0 and USB Type-C
2015-11-26
Weltrend Semiconductor (TAIEX: 2436) today announced the launch of WT7692, a fast charge interface controller chipset targeting travel adapters, car chargers, and power banks for smartphones and tablets. The controller chipset features Qualcomm® Quick ChargeTM 2.0 technology, auto detection of USB DCP applying 1.2V on D+/D- or 2.7V on D+/D-, and the industry’s emerging USB Type-CTM specification. | |
WT7692 integrates USB Type-C control logic for USB Type-C CC pin detection, blocking MOSFET control, vSafe0V discharge control, Qualcomm Quick Charge 2.0 control logic, discharge control, auto-detection circuit, and UVLO. A smart auto detect feature monitors USB D+/D- voltage and auto bias the correct voltage on the D+/D- to fast charge compliant devices. | |
WT7692 supports High Voltage Dedicated Charging Port (HVDCP) Qualcomm Quick Charge 2.0 Class A technology 5/9/12V which is able to decrease the charge time by as much as 75% of current charging time. WT7692 is suitable for USB Type-C based power charging applications such as travel adapters, car chargers, as well as power banks for Qualcomm Quick Charge 2.0 technology-compliant smartphones and tablets. | |
The WT7692 is UL verified. Read the UL Verification Certificate for WT7692. | |
