This product is a contactless charging module developed by YOSUN, specifically for charging Li-Polymer batteries. It transmits power from the TX to the RX using electromagnetic induction. It is equipped with an installation detection function, allowing the TX module (coil) to intermittently send power (DUTY = approximately 0.5%). When the RX module (coil) is installed, the TX module enters a constant power transmission mode due to installation detection. It can be used for earphones, wearable devices, toys, and more. 【Features】 ■ YOSUN's unique contactless charging module ■ Compatible with small RX coils of 7φ ■ Dedicated charging function for Li-Polymer batteries ■ Built-in 60mA charging function *For more details, please refer to the PDF document or feel free to contact us.
