Samsung presents complete chips for headsets with True Wireless Stereo (TWS) technology

THE Samsung today announced the MUA01 and MUB01, integrated power management circuits (PMICs) optimized for devices True Wireless Stereo (TWS). TWS headphones, unlike headphones, do not have a wire that connects the two parts of the device. They give the user plenty of freedom to move around and exercise, for example, and two important features for them are battery life and ergonomics.

Technology should also show dramatic reduction in energy consumption

The MUA01 and MUB01 were designed, respectively, for the charging case and for headphones in itself. With the combination of Samsung's various logical technologies, the company claims that these PMICs occupy less than half the space compared to other alternatives – leaving more room for drums or more flexible designs.

In addition, MUA01, for the case, would be the industry's first solution with support wireless and wired charging on a single chip. For this, it brings the latest Wireless Power Consortium (WPC) wireless power transfer interface standard, the Qi 1.2.4.

It also comes with a microcontroller unit (MCU) and eFlash, enabling the modification of firmware to support other applications.

The two PMICs are already in mass production and have been implemented in the recently announced Galaxy Buds + TWS from Samsung.
