supports

DCP

schemes for

battery charging specification (BC1.2), divider

mode,

1.2V/1.2V

mode,

and

quick-charge

specification (QC 3.0) without the need for

outside user interaction.

Full protection features include input over-

voltage

protection

(OVP)

and

thermal

shutdown.

The MP5034 requires a minimal number of

readily

available,

standard,

external

components to complete the USB switch and

charging mode auto-detection solution. The

MP5034 is available in an 8-pin TSOT23

package.
