Samsung has announced a new All-in-One Power ICs optimized for wireless Earbuds, this new chip is designed to help improve battery life and also enable more efficient designs on wireless earbuds.
These new chips are designed for both the earbuds and also the charging cases for the devices and they will support both wireless and wired charging.
The MUA01 and MUB01 PMICs, respectively, have been designed for the charging case and the earbuds, and are one-of-a-kind fully-integrated solutions optimized for TWS devices. 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.
The MUA01 is also the industry’s first solution to support both wireless and wired charging in a single chip. For wireless charging, it supports the Wireless Power Consortium’s (WPC) Qi 1.2.4, the consortium’s latest wireless power transfer interface standard. To provide efficient power management, the MUA01 integrates a highly effective switching charger. In addition, MUA01 comes with a microcontroller unit (MCU) and embedded Flash (eFlash), offering the option of modifying its firmware to support other applications.
