Moreover, this chip supports charge pump 2:1 step-down charging (high-voltage fast charging) and bypass charging (low-voltage direct charging) dual modes, achieving a balance between fast charging and temperature control, and the maximum output current supports up to 8A.
Furthermore, Nanxin SC8551A has a built-in dual charge pump to step down, and the conversion efficiency is as high as 98%. The chip integrates a switch MOS tube and integrates complete protection functions, such as input overvoltage, output overvoltage, output overcurrent, battery terminal overvoltage, overcurrent protection, etc.
It has a built-in 12-bit ADC for bus voltage and current detection, output Voltage, battery voltage, die temperature, and other measurable parameters for protection during battery charging. The Honor Magic 4 is equipped with a 4800mAh battery, supports 66W wired super-fast charging, the processor is Snapdragon 8, and the price starts from USD 629.
