This True Wireless Stereo (TWS) and hearing aid earbud charger cradle/box solution integrates USB-C, legacy USB-A and wireless power inputs paths with a highly optimized TWS charger power management IC (PMIC).
The charger PMIC combines a DC/DC buck charger with a reverse boost function and two separately controlled LDOs to provide individually controlled voltage levels to the earbuds. The solution also offers optional UART-based power line communication (PLC) to control the required charging voltage and communicate SoC/SoH information and more.
