XySemi XB5152I2SZR integrated lithium battery protection IC, XB5152 ZR series products are highly integrated solutions for lithium ion/polymer battery protection. Contains advanced power MOSFETs, high-precision voltage detection circuits and delay circuits in an ultra-small SOT23-5 package with only one external component, making it an ideal solution for limited space in battery packs.
According to 52audio, TWS earbuds of Xiaomi, OPPO, Redmi, Honor, Edifier, realme, Motorola, Anker, RAPOO, QCY and many other brands have adopted XySemi lithium battery protection IC.
Two metal thimbles for charging the earphone in the charging case.
The LPS LP6261 ultra-low quiescent current synchronous boost converter is used to boost the built-in battery in the charging case to charge earphones.
The LP6261 has a TRUE shutdown function, which can disconnect the input and output under shutdown and output short-circuit conditions, and the 1.2MHZ switching frequency can use small volume inductors and capacitors. The switch pin adopts a high-voltage 9V process, which can effectively absorb the high-voltage peak of the production capacity when the earphone is unplugged and plugged. At the same time, the LP6261 has no whistling sound within the full load capacity range (especially light load).
The LP6261 consumes only 1UA of quiescent current under light load conditions and can achieve up to 75% efficiency under 20uA load. The conversion efficiency from 3.3V to 5V is as high as 93% under 200mA load.
According to 52audio, there are audio products from Black Shark, FIIL, Xiaomi, Honor, OPPO, Huawei, Redmi, realme, Lenovo, Sony, Nokia, Motorola, Edifier, Soundcore, 1MORE, QCY, Razer and many other brands. The product adopts LPS power management chip.
Cooperate with the boost chip to boost the built-in battery to charge the earphone.
LPS LP4067T charging IC is a single-chip single-cell lithium battery charging chip. The internal integrated MOS tube does not require external current sampling resistors and diodes, and the number of peripheral components is small.
The LP4067T supports 30V input withstand voltage, the overvoltage protection point is 6.3V, the maximum charging current is 800mA, and it supports battery reverse connection protection. It also supports NTC to detect battery temperature to further improve charging safety.
Screen-printed 23P TVS for input overvoltage protection.
