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.
