Samsung introduces All-in-one Power ICs for TWS earphones

[BADSHAH18]

With the truly wireless earphone market growing at a rapid pace, Samsung has decided to invest in the internal electronics of a TWS earphone, launching its first All-in-One Power ICs. They are highly optimized ICs for this category to provide for longer battery life and more efficient designs.

The new power management integrated circuits (PMIC), MUA01 and MUB01, are designed for the charging case and the earbuds respectively. It integrates up to ten discrete components into one, including switching chargers and discharge circuits, for highly efficient and smaller design. This allows bigger batteries and hence better battery life. It also supports both wireless and wired charging in a single chip.

The MUA01 and MUB01 are currently in mass production and are found in Samsung’s Galaxy Buds+ TWS earbuds that were announced recently.

Commenting on the launch, Dong-ho Shin, senior vice president of System LSI marketing at Samsung Electronics said:

Qualcomm’s QCC514X and QCC304X Bluetooth SoCs

As for Qualcomm, they’re unveiling new Bluetooth system-on-chips for truly wireless earbuds. QCC514X and QCC304X are the newest SoCs from the company for premium and entry-level TWS devices, respectively. Both of them come with Voice Assistant support and Qualcomm’s Hybrid Active Noise Cancellation (Hybrid ANC) on the hardware level. The latter allows for low-latency leak-through, meaning that you’ll be able to take advantage of noise cancellation in airplanes as well as when you’re just walking down the street. Qualcomm also promises “premium wireless sound and voice quality.” In addition, the two SoCs support Qualcomm’s new TrueWireless Mirroring technology. According to the press release, with this technology, “one earbud is wirelessly connected to the phone via Bluetooth while the other bud mirrors the connected bud and is engineered to deliver a rapid swap under several scenarios.” The premium QCC514X supports always-on voice activation to trigger the digital assistant, while the entry-level QCC304X only supports push-to-talk.
