Cxlb7464 is a compact mobile power chip which integrates charge management charge and discharge indicator lights flashlight control and synchronous boost DC-DC functions

Cxlb7464 is a compact mobile power chip, which integrates charge management, charge and discharge indicator lights, flashlight control and synchronous boost DC-DC functions, especially suitable for small mobile power supply and other portable electronic devices. The chip has built-in charge management, which charges the battery according to the standard trickle, constant current and constant voltage three-stage charging mode, effectively guarantees the charging safety and battery life, and ensures that the battery reaches full charge, and is driven by the corresponding power indicator. The chip has built-in synchronous boost DC-DC, internal integrated power switch, external only needs inductance and capacitance to realize complete boost function, without external Schottky diode, and can output up to 1.0A current. Built in short-circuit and over-current protection functions can realize the output short-circuit protection function independently without external switching devices, and can still guarantee the safety and reliability of the system under the condition of abnormal load access. Cxlb7464 has built-in charging and discharging power MOS, with fixed charging current of 0.6A and battery voltage above 3.3V, which can output enough 1A current
