South Core: Honor Magic 4 uses its SC8551A charging chip to achieve 66W fast charging

IT House News on April 1st, according to the official news of Nanxin, the latest Magic 4 released by Honor is equipped with its SC8551 charging chip.

Officially, Nanxin SC8551A, using CSP56pin, 2.995*3.255mm package, has successfully entered the mid-to-high-end domestic mobile phone supply chain, breaking the “monopoly” of European and American manufacturers, and becoming one of the important milestone products in the rise of domestic power chips.

This chip supports dual modes of charge pump 2:1 step-down charging (high-voltage fast charging) and bypass charging (low-voltage direct charging), achieving a balance between fast charging and temperature control, and the maximum output current supports up to 8A. Nanxin SC8551A has 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 and overcurrent protection, etc.; 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.

IT House learned that the Honor Magic 4 is equipped with a 4800mAh battery, supports 66W wired super fast charging, the processor is Snapdragon 8 Gen1, and the price starts from 3999 yuan.
