DESCRIPTION

The MP5032 integrates a USB current-limit

switch and charging port identification circuit.

The MP5032 achieves 3A of continuous output

current over a wide input supply range.

The output of the USB switch is current-limit

programmable. The MP5032 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 external user interaction.

The

MP5032

provides

linear

line

drop

compensation.

Full protection features include hiccup current

limiting, input over-voltage protection (OVP),

and thermal shutdown.

The MP5032 requires a minimal number of

readily

available,

standard,

external

components to complete the USB switch and

charging mode auto-detection solution. The

MP5032 is available in an 8-pin TSOT23

package.
