| 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. |
