Weiyuan Semiconductor is an advanced simulation chip design company in the industry, which focuses on the field of simulation chips based on power management chips.In this planLP7810QVF is an efficient charging management IC. It has a built -in 30V input resistance, with charging, voltage, NTC management, LDO, and multiple protection circuits.It also has a dual -channel in the headset and independently enter the warehouse inspection. It supports two -way communication with the headset. The charging parameters can be set through the I2C bus, and the MCU will be sent to the MCU to maximize the battery life when specific events occur.
LP5305QVFIt is an over -integrated voltage/overcurrent protection chip with high intensive degree. It has 30V resistance and 85V input overvoltage protection, which can prevent the system from the effect of abnormal high input voltage.In addition, the LP5305QVF can also monitor the battery voltage in real time. When the battery voltage exceeds 4.35V, the IC will turn off the MOS to further protect the system.
In addition, this solution also uses AB132A MCU of Zhongke Lanxun and AW86504str Hall sensor of Ai Weiche Electronics.Zhongke LanxunAB132A MCUBased on the 32 BIT RISC-V core, the main frequency can reach 120MHz.Its built -in 4 -way low -power capacitance touch button and soft switch PMU circuit support the PWRKEY key to wake up and 5V charging wake -up function.Not only that, AB132A also has a built -in CODEC (codec), which has 95DB high -performance stereo DAC signal -to -noise ratio.In terms of packaging design, this product is packaged with 4mm × 4mm QFN32, which helps the product miniaturizes.
