The IP5320 is a multi-function power management SOC that integrates a boost converter, lithium battery charge management, and battery level indication, providing a complete power solution for the digital tube display mobile power supply.

    The high integration and rich functions of the IP5320 make it require few peripheral devices in application, and effectively reduce the size of the overall solution and reduce the BOM cost.

    The IP5320 requires only one inductor to achieve buck and boost functions. Can support low cost inductors and capacitors.

    The IP5320‘s synchronous boost system provides rated 3A output current with a conversion efficiency of up to 95%. When unloaded, it automatically enters the sleep state, and the static current is reduced to less than 150uA.

    The IP5320 uses switch charging technology to provide rated 3A charging current and charge efficiency up to 93%. The built-in IC temperature and input voltage intelligently regulate the charging current.

    The IP5320 has a built-in 10-bit ADC with a built-in current sampling circuit to accurately measure battery voltage and current. IP5320 built-in power calculation method, can accurately obtain the battery power information. Battery capacity can be set to accurately display battery power.

    IP5320 support 1/2/3/4 LED power display, support 88, 188 and other digital tube power display; Support lighting function; Buttons are supported.

    The IP5320 supports the I2C control interface.
