All-in-One Energy Administration ICs Optimised for Wi-fi Earbuds


  • The facility administration ICs by Samsung Digitals include built-in discrete elements that saves house for battery that permits longer playback time
  • The ICs additionally present communication between the charging case and earpieces to share important data similar to battery ranges

Samsung Electronics’ all-in-one energy administration built-in circuits (PMICs), MUA01 and MUB01 supply a high-quality listening expertise for immediately’s True Wi-fi Stereo (TWS) gadgets.

In contrast to wi-fi headphones, TWS earbuds shouldn’t have a wire connecting the 2 earpieces, which permits customers of TWS gadgets extra freedom in motion and vary in day-to-day actions. Nevertheless, like different cell gadgets, lengthy battery life and small kind components are key necessities for these wi-fi earbuds.

The MUA01 and MUB01 PMICs have been designed for the charging case and the earbuds, providing fully-integrated options optimised for TWS gadgets. To realize this, as much as ten discrete elements have been built-in into one, together with switching chargers and discharge circuits, enabling the PMICs to occupy lower than half the house in comparison with different options. This additionally permits compact options to allocate extra room for the battery for longer playback time and allow extra versatile and environment friendly designs.

Twin charging help

The MUA01 can also be the {industry}’s first answer (as claimed by the corporate) to help each wi-fi and wired charging in a single chip. For wi-fi charging, it helps the Wi-fi Energy Consortium’s (WPC) newest wi-fi energy switch interface commonplace, the Qi 1.2.4. To supply environment friendly energy administration, the MUA01 integrates a extremely efficient switching charger. Moreover, MUA01 comes with a microcontroller unit (MCU) and embedded Flash (eFlash), providing the choice of modifying its firmware to help different functions.

“TWS earbuds current elevated listening experiences for extra customers and the pattern is quickly increasing the cell accent market, creating new alternatives for machine producers,” mentioned Dong-ho Shin, senior vp of System LSI advertising and marketing at Samsung Electronics. “Samsung’s industry-first, all-in-one energy administration options optimized for TWS gadgets will permit producers to craft new functions with larger flexibility.”

With energy line communication (PLC) help, the brand new PMICs can talk with one another over the charging pins. This permits the charging case and earpieces to share important data similar to battery ranges and whether or not the earpieces are inserted within the case.

The MUA01 and MUB01 are presently in mass manufacturing and are featured in Samsung’s recently-announced Galaxy Buds+ TWS earbuds.
