USB Power and Charging Port Controllers
WT6617F
【 General Description 】 |
The WT6617F is a highly integrated USB Power Delivery (USB PD) controller that supports USB PD 3.0 Programmable Power Supply specification and Qualcomm® Quick ChargeTM 4 or Quick Charge 4+ technologies. With AEC-Q100 certification for automotive-grade performance, the WT6617F is designed for automotive USB Type-C® power source applications such as seat chargers, infotainment unit chargers, and etc. |
The WT6617F minimizes external components by integrating USB PD baseband PHY, USB Type-C detection, shunt regulator, voltage and current monitors, NMOS load switch driver and an 8-bit MCU to allow small form factor and low BOM cost. Wide operation voltage range (3V to 24V) supports PD 3.0 Programmable Power Supply (PPS) specification. A Multi-Time-Programmable (MTP) ROM is provided for program code and user configuration data. |
The WT6617F is certified by USB Implementers Forum (USB-IF) for USB Type-C PD (TID: 2166). |
