Recently, Anker held a new event and released the USB PD 3.1 fast charging lineup. Anker has partnered with WELTREND to debut an exclusive PD 3.1 protocol chip.

ChargerLAB has learned that the chip, WT6676F, is designed for USB Type-C power source applications such as power adapters, wall chargers, car chargers, power strips, etc. Its wide operation voltage range (3.3V to 45V) supports USB PD 3.1 SPR & EPR 36V specifications.

The WT6676F 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. A Multi-Time-Programmable (MTP) ROM is provided for program code and user configuration data.

The WT6676F featured programmable constant voltage and current control, integrated a low side current sense amplifier, and supported cable drop compensation. It also supports over voltage, under voltage, over current and over temperature protection.

Based on the performance of the WT6676F, Anker has launched 3 products that perfectly support the PD 3.1, 140W Anker 717 Charger, the 24,000 mAh 737 Power Bank and a new 765 C-to-C Cable.
