The IIP5513 is a multi-functional power management SoC that integrates a 5V boost converter, lithium battery charging management, and battery power indication. It provides a complete power solution for TWS Bluetooth earphone charging cases. The high integration and rich features of the IP5513 allow it to require only a minimal number of external components during application, effectively reducing the overall solution size and lowering the BOM cost. The IP5513 incorporates a 5V output, synchronous rectification boost DC-DC converter with an integrated power transistor, providing a maximum output current of 300mA and a boost efficiency as high as 93%. The DC-DC converter switching frequency is 1.5MHz, supporting low-cost inductors and capacitors. The IP5513's linear charging provides a maximum charging current of 500mA, with flexible configuration of the maximum charging current. It has built-in IC temperature and input voltage intelligent charging current adjustment functions. The IP5513 can achieve independent in-case detection for TWS earbuds. Upon detecting earbuds in the case, it automatically enters the earbud charging mode, and automatically enters sleep mode after the earbuds are fully charged, with a minimum static current as low as 30uA. The full-charge current can be flexibly customized, with a full-charge current detection accuracy of up to 1mA. The IP5513 has a built-in MCU, allowing for flexible customization of 4/3/2/1 LEDs or a 188 digital tube power display. With a built-in 10-bit ADC, it can accurately calculate the battery power. The IP5513 uses a SOP16 package.
