Hall Switch Circuit Selection Guide for 1.2V Always-On TWS Systems
In today’s True Wireless Stereo (TWS) earphones, power efficiency is no longer a single-parameter optimization problem. Whether in the charging case or the earphone itself, TWS systems are defined by extremely small form factors, severely constrained PCB resources, and limited battery capacity. Under these conditions, even microamp-level current consumption can significantly affect standby time and overall user experience. At the same time, modern TWS products are integrating more Always-On functions, such as lid detection, in-ear detection, voice wake-up, and smart interaction. These features rely on sensors and logic blocks that remain powered continuously, making the design of the hall switch circuit a system-level decision rather than a simple component choice. True Wireless Stereo Application Why the Hall Switch Circuit Has Become a ...
