XYT4256

    XYT4256 is a dual series lithium battery synchronous boost charging chip with high integration and high reliability.
    XYT4256 can be configured with external resistance charging current, the charging system integrates 3 loops: input voltage, output voltage and output current, providing excellent performance for the charging system. The charging efficiency is 94% when the input voltage is 5V, the BAT voltage is 8.4V, and the charging current is 1.2A. Charging integrates various protection functions: input overvoltage, input undervoltage, output overvoltage, output short circuit, chip overtemperature, and a maximum charging time of 24 hours.
