Samsung Introduces Industry’s First All-in-One Power ICs Optimized for Wireless Earbuds
Summary
SEOUL, South Korea--(BUSINESS WIRE)--Samsung Electronics Co., Ltd., a world leader in advanced semiconductor technology, today announced the industry’s first all-in-one power management integrated circuits (PMIC), MUA01 and MUB01, optimized for today’s True Wireless Stereo (TWS) devices. However, like other mobile devices, long battery life and small form factors are key requirements for these wireless earbuds. By combining several of the company’s in-house logic technologies, Samsung was able to integrate up to ten discrete components into one, including switching chargers and discharge circuits, enabling the PMICs to occupy less than half the space compared to previous alternatives. The compact solutions can allot more room to the battery for longer playback time and enable more flexible and efficient designs. In addition, MUA01 comes with a microcontroller unit (MCU) and embedded Flash (eFlash), offering the option of modifying its firmware to support other applications.
