The XYT4258 is a two-section lithium battery boost charge management IC with high integration and reliability. The XYT4258 charging current can be configured with external resistors, and the charging system integrates three loops: input adaptive loop, constant voltage output loop, and constant current output loop, providing excellent performance for the charging system. The XYT4258‘s boost switch charge converter operates at 650KHz with a maximum 2.5A input charge and a conversion efficiency of 90%. The XYT4258 has an input voltage of 5V and a built-in adaptive loop to intelligently adjust the charging current and match all adapters.

    XYT4258 integrates power MOS and adopts asynchronous switching architecture, so that it needs few peripheral devices at the time, which can effectively reduce the overall solution size and reduce BOM cost. The XYT4258 integrates complete protection features: input overvoltage, input undervoltage, output short circuit, output overvoltage and chip overtemperature protection.
