As power bank SoC, the 3-in-1e chip can realize the overall function of a single-cell mobile power bank on a single chip, it supports up to 4 ports charge and discharge management, button and power indication, automatic standby and wake-up functions. Without MCU, a single chip implements the entire system, which is simple and efficient, and is the best choice for a low-cost solution; the 2-in-1 charging chip can be used with MCU to realize the overall function of a single-cell mobile power supply, it also supports up to 4 ports charge and discharge management, button and power indication, automatic standby and wake-up functions. With MCU, it allows flexible configuration of multiple functions such as charging voltage, key function, power indicator, and NTC protection to create a differentiated mobile power solution.
