  The wireless charging management chip CH246 integrates wireless charging transceiver module and small signal decoding circuit in a single chip, which can easily realize various wireless charging solutions such as Qi. CH246 supports PD2.0, BC1.2 multiple protocols fast charging input, 5W, 7.5W, 10W, 15W wireless charging output, integrated FSK/ASK decoding, overvoltage, overcurrent, overtemperature detection protection, high integration, few external devices, can be widely used in various wireless charging base brackets and other designs. CH246 uses OTP process, which is suitable for charging solutions with clear requirements and cost optimization. The Flash process PD and wireless charging dedicated MCU CH641 is more functional and flexible, and can quickly build differentiated wireless charging products.
