description: |
  MT6370 is a highly-integrated smart power management IC, which includes a
  single cell Li-Ion/Li-Polymer switching battery charger, a USB Type-C &
  Power Delivery (PD) controller, dual flash LED current sources, a RGB LED
  driver, a backlight WLED driver, a display bias driver and a general LDO for
  portable devices.
