As a core supplier of PD fast charging and TWS earphones for Apple in the long term, the audio brand Soundcore has always performed well. Recently, Soundcore released the latest generation of Soundcore Liberty 3 Pro Soundcore with ACAA 2.0 coaxial coil iron technology.
In addition to its colorful color scheme and round and lively appearance, its configuration is also “particularly impressive”:
Knowles dynamic iron and 10.6mm dynamic coil ACAA2.0 coaxial coil iron design, supporting active noise reduction;
● HearID can intelligently analyze the user’s hearing condition, adjust the sound settings for listening, and enable users to perceive the surrounding environment through transparency mode; The Liberty3 Pro has a 30% reduction in volume compared to its predecessor, and is designed ergonomically with pressure relief adjustments made to the ear fins, making it more suitable for different user needs in terms of comfort. In terms of battery life, the Liberty3 Pro has also maintained its expected level, supporting fast charging and wireless charging, with a 7-hour single 35 hour overall battery life.
The release of the Liberty3 Pro, known as the “Superpower Little Easter Egg,” has sparked many expectations. Behind the high attention, it is the focus of our introduction in this issue:
Liberty3Pro uses the P14C1N overvoltage and overcurrent protection IC and the electrostatic protection device PESDHC2FD6V3UF from Xindao Technology this time.
The overvoltage and overcurrent protection IC P14C1N developed by Xindao Technology is applied to the charging case motherboard of Liberty3Pro, and its advantages such as high precision and fast overvoltage protection response are highly recognized by customers.
The DC withstand voltage of P14C1N is as high as 32V, and the overvoltage protection point is fixed at 6V. In addition, its overcurrent protection point peripheral resistance is adjustable, the overcurrent response time peripheral is adjustable, and the overcurrent protection accuracy of 10mA can meet the overcurrent protection requirements of different adapters and various products, with a wide range of application scenarios.
Another electrostatic protection device used, PESDHC2FD6V3UF, is applied to the headphone power input of Liberty3Pro:
This is an ESD protection device with high IP and low Vc. Its main performance and characteristics:
In addition to the above two materials, Liberty3Pro also uses multiple MOS and ESD protection devices from Prisemi, such as PNMT20V3, PPMT30V4, PESDNC2FD7VB, PESDNC2FD24VB, PESDNC2XD3V3B, PESDNC2XD5VBF, PESDNC2XD5VBF, etc., to ensure the stable and safe operation of TWS earphones. The ultra small packaging used in the Prisemi Small and Beautiful series products occupies a smaller area in the TWS products that are worth every inch of land and money, and is more cost-effective.
Of course, Prisemi has developed a series of adaptive materials for different TWS needs. If you have any requirements, please contact us through:
