Samsung’s chip business isn’t just Exynos SoC, memory and flash data storage, it also produces many chips, including smaller power management integrated chips (PMICs). In its latest announcement, Samsung announced that it has launched mass production of PMIC, which provides longer battery life and larger batteries for the Galaxy Buds-Plus wireless headset.

The True Wireless Smart Headset (TWS), which includes Apple’s AirPods, is very compact in size, leaving little room for internal components, so battery cases are often used to provide extra assurance.

Accessories manufacturers shrink and fill the headphone elements as much as possible to provide more space for the battery. The Samsung MUB01 chip used by The Galaxy Buds is typical. It combines five discrete components into a single chip to reduce the size of the board’s internal footprint, meaning more battery space is available.

In addition, the MUA01 chip in the charging box compresses 10 components into a single chip, and this PMIC is the industry’s first cable and Qi wireless charging product. It even includes a microcontroller and embedded Flash, so its firmware can be updated later to add more functionality.

Both chips are already on the Galaxy Buds plus headphones, but with mass production, Samsung is opening its doors to other accessories makers.
