Due to its advantages of high voltage, high energy density, long cycle life and fast charging, lithium batteries are widely used in a variety of electronic products such as TWS earphones and become the preferred power supply. However, improper use such as overcharge, overdischarge, or abnormal current may cause potential safety hazards and pose a threat to user safety. In order to ensure safety, most TWS earphones are integrated with an overvoltage current protection chip to ensure that the battery maintains a stable and safe working state during charging and discharging. These protective measures are essential to improve the reliability of the product and the safety of the user.
E5 is an open-ear clip headphone recently launched by Xiao Tiancai, which has won the favor of many consumers because of its unique design. I love audio network recently through dismantling to gain an in-depth understanding of the little genius E5, and found that its charging case is equipped with SY5320 over-voltage and over-current protection IC from Siyuan Semiconductor to ensure the safe charging and discharging of earphones.
Whether it is the charging case or the earbuds body, the appearance is a highlight of the little genius E5. The charging case is first of all transparent, and the "electronic components" engraved on the surface can be seen from the front, which is very technological. The overall shape is inspired by the "Radiant" diamond cutting process, with a clear and linear appearance. The earphone body adopts an innovative physically adjustable ear clip design, and a hovering hinge structure is installed at the tail to fit different sizes of ear pinna.
In terms of functional configuration,Little geniusE5Equipped with exclusive sound field directional gain technology,Ensure that the sound is concentrated without sound leakage。 DRC intelligent tuning technology also enhances the bass effect of the E5, and the details are richer. The headset is 4.9 grams per ear, which is more comfortable to wear. It has a total battery life of 27 hours and also supports IPX4 life waterproofing. Little Genius E5 has two colors: Dark Mirror Black and Moon Shadow White.
After the dismantling of the audio network, it was found that the little genius E5 charging box has a built-in 800mAh lithium battery, and its motherboard integrates a boost converter, a boost inductor, an LED indicator, and an AD type Flash microcontroller and boost converter and other components for charge and discharge management. Among them, the over-voltage and over-current protection IC comes from Siyuan Semiconductor's SY5320, which has the functions of over-voltage protection, load current abnormal protection and over-temperature protection to help the headphones charge and discharge safely.
Siyuan Semiconductor SY5320 over-voltage and over-current protection IC is a highly integrated protection IC with input under-voltage and over-voltage protection, lithium battery front-end over-voltage protection, load current abnormal protection and over-temperature protection, supporting 28V input withstand voltage, over-voltage shutdown protection less than 1uS, supporting high-precision battery over-voltage protection function, using DFN-2x2-8L package.
