Weltrend is pushing the boundaries of high-voltage battery management with its new WT6679F controller. Built for the era of 240W USB-C charging, this chip is designed to streamline power delivery for e-bikes and portable storage units.
By supporting the PD3.2 EPR 48V specification, the WT6679F allows for efficient 48V/5A power transmission, solving the heat and loss issues typically associated with high-amperage cables. Its DRP (Dual Role Power) capability is a highlight—a single USB-C port can now both charge the battery and power external high-drain devices like laptops, effectively reducing hardware clutter.
With its wide 4V–66V operating range and integration of power conversion control, the WT6679F acts as a complete "system-on-a-chip" for battery packs. From comprehensive OVP/OCP/UVP protections to E-Marker identification and liquid detection, it’s a robust solution for developers aiming to integrate safe, high-speed USB-C charging into demanding power applications.
