Fast charging technology has flourished in the middle of recent years, and the charging power of electronic products has been continuously improved, creating favorable conditions for the development of the high-power mobile fast charging source market. The fast charging chip is a power management SOC for multi-port high-power fast charging applications. It integrates a microprocessor, a buck-boost converter, a fast charging protocol controller, and supports PD3.1, QC3.0, QC2.0, AFC, FCP, SCP and other mainstream fast charging protocols can be combined with a small number of components to form a 140W dual independent dual C port high power fast charging solution. Supplemented by a DC-DC chip, it can also be expanded into a 3-way independent CC+AA multi-port fast charging solution.
M12029—Small appliances/electric tools fast charging SOC
M12029 is a dedicated SOC for fast charging of small household appliances/electric tools. It integrates functional modules such as synchronous switching boost converter, fast charging protocol controller, battery charging and discharging management, battery power calculation, power display, and motor control. PD3.1, QC3.0, AFC, FCP, SCP and other fast charging protocols, the maximum charging power is 140W, and it provides complete protection functions such as input overvoltage/undervoltage, overtemperature, and overcurrent protection. With simple peripheral circuits, a fast charging solution for small household appliances and power tools can be formed.
