IP6818 is a multi-functional power management SoC that integrates Qi wireless charging receiver, 5V boost converter, lithium battery charge management, and battery power indication. It provides a complete power solution for wireless charging TWS Bluetooth earphone charging cases. The high integration and rich functions of IP6818 allow it to use only a few external components during application, effectively reducing the overall size of the solution and lowering the BOM cost. IP6818 has a built-in 5V output, synchronous rectification boost DC-DC, with an internal power tube, providing a maximum output current of 300mA and a boost efficiency as high as 93%. The DC-DC converter switching frequency is 1.5MHz, which can support low-cost inductors and capacitors. IP6818's linear charging provides a maximum charging current of 500mA and allows flexible configuration of the maximum charging current. It has built-in IC temperature and input voltage intelligent adjustment charging current function. IP6818 can achieve independent in-bin detection of TWS earbuds. After detecting that the earbuds are in the bin, it automatically enters the earbud charging mode. After the earbuds are fully charged, it automatically enters the sleep state, and the static current can be reduced to as low as 20uA. The full-charge current can be flexibly customized, and the full-charge current detection accuracy is as high as 1mA. IP6818 has a built-in MCU, which can flexibly customize the display of 4/3/2/1 LEDs or a 188 digital tube. It has a built-in 12-bit ADC for accurate calculation of battery power. IP6818 uses a QFN24 package.
