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