The new PMICs combine a number of discrete elements in a single chip
to make room for longer battery life
and extra environment friendly designs in at this time’s True Wireless Stereo units
Samsung Electronics, a world chief in superior semiconductor expertise, at this time introduced the business’s first all-in-one energy administration built-in circuits (PMIC), MUA01 and MUB01, optimized for at this time’s True Wireless Stereo (TWS) units.
Unlike wi-fi headphones, TWS earbuds haven’t any wire that connects the 2 earpieces. Without the connecting wires, TWS units current customers with extra freedom in motion and vary on their day-to-day actions. However, like different cellular units, lengthy battery life and small kind components are key necessities for these wi-fi earbuds.
“TWS earbuds present elevated listening experiences for more users and the trend is rapidly expanding the mobile accessory market, creating new opportunities for device manufacturers,” mentioned Dong-ho Shin, senior vp of System LSI advertising at Samsung Electronics. “Samsung’s industry-first, all-in-one power management solutions optimized for TWS devices will allow manufacturers to craft new applications with greater flexibility.”
The MUA01 and MUB01 PMICs, respectively, have been designed for the charging case and the earbuds, and are one-of-a-kind fully-integrated options optimized for TWS units. By combining a number of of the corporate’s in-house logic applied sciences, Samsung was in a position to combine as much as ten discrete elements into one, together with switching chargers and discharge circuits, enabling the PMICs to occupy lower than half the house in comparison with earlier alternate options. The compact options can allot extra room to the battery for longer playback time and allow extra versatile and environment friendly designs.
The MUA01 can also be the business’s first answer to assist each wi-fi and wired charging in a single chip. For wi-fi charging, it helps the Wireless Power Consortium’s (WPC) Qi 1.2.4, the consortium’s newest wi-fi energy switch interface customary. To present environment friendly energy administration, the MUA01 integrates a extremely efficient switching charger. In addition, MUA01 comes with a microcontroller unit (MCU) and embedded Flash (eFlash), providing the choice of modifying its firmware to assist different functions.
With energy line communication (PLC) assist, the brand new PMICs can talk with one another over the charging pins. This permits the charging case and earpieces to share important info akin 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.
