IT Home April 1 news, according to the official news of The South Core, Honor's latest release of magic 4 is equipped with its SC8551 charging chip.
Officials said that nanxin SC8551A, using CSP56pin, 2.995 * 3.255mm package, has successfully entered the high-end domestic mobile phone supply chain, breaking the "monopoly" of European and American manufacturers, and becoming one of the important milestone products for the rise of domestic power chips.
The chip supports charge pump 2:1 buck charging (high voltage fast charge) and bypass charge (low voltage direct charge) dual modes, which balance fast charging and temperature control with a maximum output current of 8A. The SOUTH CORE SC8551A has a built-in dual charge pump to step down and convert up to 98% efficiency. The chip integrates a switch MOS tube to integrate perfect protection functions such as input overvoltage, output overvoltage, output overcurrent, battery-side overvoltage and overcurrent protection, and built-in 12-bit ADC for bus voltage current detection, output voltage, battery voltage, chip temperature and other measurable parameters for protection during battery charging.
IT Home learned that honor Magic 4 is equipped with a 4800mAh battery, supports 66W wired super fast charging, and the processor is Snapdragon 8, priced from 3999 yuan.
