*Function: Include power bank for Li battery and power management for wireless earphone.
  Integrate 2 functions of charge control and dc-dc step-up.
*Features:
-PPI, dynamic power path control: higher priority to charge wireless earphone from input power.
-When battery is plugged, base on battery voltage level, go into suitable related charge process flow.
-Constant Current mode, which Fast Charge current is set by external resistors.
-Battery is charged full when charge current is lower than 15% of setting level, 0.15C.
-Multiple protect functions: Over charge voltage protect, over charge current protect,
 over discharge battery protect.
-Soft start of power output circuit for isolated battery power leaking out.
-Auto stop power out when battery voltage reach low level.  
-4 LEDs display: Mobile battery capacity, earphone module power supply status.
