Weltrend Launches WT6616F DRP USB PD Controller
2019-05-20
Hsinchu, Taiwan, May 20, 2019 – Weltrend Semiconductor (TWSE: 2436) today announced the launched of WT6616F, a highly integrated Dual Role Port (DRP) USB Power Delivery (PD) controller that supports USB PD 3.0 Programmable Power Supply specification. It is designed for device that supports dual-role USB PD functions such as power banks. | |
The WT6616F minimizes external components by integrating USB PD baseband PHY, 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. | |
