The RLCP5305 is a single-chip power-management

SOC integrating linear charging management, synchronous boost conversion, battery-level indication and multiple protection functions, providing a complete single-chip power solution for lithium-battery devices such as power banks. The RLCP5305 integrates a linear charging management

module, a synchronous boost discharge management module, a battery-level detection and LED indication module, and multiple protection modules. The RLCP5305 integrates charging and discharging

power MOS; the charging current is fixed at 1A. The maximum synchronous boost output current is 1A, and the light-load shutdown current of the discharge load is 50mA.

The RLCP5305 has low standby power consumption; when the chip is off and the load is open, its standby current can be as low as 14uA. The RLCP5305

integrates temperature compensation, over-temperature protection, over-charge and over-discharge protection, output over-voltage protection, output over-current protection, output short-circuit protection and other safety

protection functions to ensure the safety of the chip and the lithium-ion battery. The RLCP5305 requires a simple application circuit with very few external components to implement a complete lithium-

battery charge/discharge solution, greatly saving system cost and size.
