Recently, I Love Audio Network published an article titled “TWS Headphone Chip Battle: Domestic Vs International!” This article categorizes the current state of the TWS headphone chip market by local and international methods. Next, we will successively introduce detailed information about each type of chip and chip manufacturers in TWS headphones to help all parties in the supply chain gain more insights.
Previously, I Love Audio Network analyzed the TWS headphone Bluetooth audio SOC, and this time we will discuss power management chips.
The rapid development of TWS headphones is largely due to their portability. The primary condition for achieving the freedom from wired constraints is the inclusion of built-in batteries. TWS headphones consist of three parts: the charging case battery and the left/right earpieces.
The charging case battery charges the headphone batteries, which provide energy support for various functions such as wireless music playback, voice calls, and noise cancellation. During this process, the power management chip plays a crucial role.
The power management chip is primarily responsible for charging the internal battery of the charging case and boosting the output to charge the headphones, as well as providing safety protections against overcharging, over-discharging, over-current, and short circuits for the built-in lithium battery. It enhances battery charging speed, precisely controls current and voltage, and reduces damage to the headphone battery.
Although the power management chip of the charging case has relatively low charging and discharging power compared to traditional devices, it has higher requirements for reliability, low power consumption, high efficiency, precision, compatibility, and integration for TWS headphones, which demand high portability.
The research results of I Love Audio Network’s “2021 TWS Headphone Industry White Paper” show that there are a wide variety of power management chip products, fragmented application markets, and a large overall market scale. However, before 2019, there were very few power management chips specifically designed for TWS headphones in the domestic market, and brand manufacturers mainly procured foreign products at relatively high prices.
With the explosive growth of the TWS headphone market, many well-known domestic manufacturers have invested in this field and gradually surpassed their predecessors. I Love Audio Network has often seen power management solutions from manufacturers such as Yutai, Shengbangwei, Si Yuan Semiconductor, MicroSource, Silergy, and Shengshengwei; products from brands like Diodes, Maxim, NXP, Samsung, and TI are mostly used in mid-to-high-end TWS headphone products of overseas brands.
