The new USB-A fast charging protocol control chip HUSB601, which has passed QC3+ certification and supports up to 20V charging voltage

9 6, 2022

Recently, Hynetek has launched a highly integrated USB-A fast charging protocol control chip HUSB601, which has passed QC3+ certification, certificate number QC20210519235. HUSB601 supports mainstream fast charging protocols such as BC1.2 DCP, Apple 5V, 2.4 A, Samsung AFC, QC2.0/3.0 (Type A and Type B), QC3+, Huawei FCP and SCP, and can be configured with a charging voltage up to 20V. Suitable for wall adapters, car chargers, portable power boxes, common USB-A output ports, and more.

Application scenarios of HUSB601

| HUSB601 can automatically detect the connected power supply device and match the best charging protocol to achieve the best charging effect.

When the HUSB601 is operating, the state of the SEL pin can be dynamically changed, and the charging state is also dynamically switched between fast charging and 5V charging, which is compatible with power attenuation applications in charging systems with multiple charging ports.
