DESCRIPTION

The MP5030C integrates a USB current-limit

switch and charging port identification circuit.

The MP5030C achieves 3A of continuous

output current over a wide input supply range.

The output of the USB switch is current-limit

programmable.

The

MP5030C

supports

dedicated charging port (DCP) and charging

downstream port (CDP) schemes for battery

charging specification (BC1.2), divider mode,

1.2V/1.2V mode, and quick-charge specification

(QC 2.0/3.0) without the need for external user

interaction.

The

MP5030C

provides

linear

line

drop

compensation for 5V outputs.

Full protection features include hiccup current

limiting, input over-voltage protection (OVP),

and thermal shutdown.

The MP5030C requires a minimal number of

readily

available,

standard,

external

components to complete the USB switch and

charging mode auto-detection solution. The

MP5030C

is

available

in

a

QFN-10

(1.5mmx2mm) package.

FEATURES

 Up to 14V Operating Input Voltage Range

 Support DCP Schemes for BC 1.2 without

QC Mode, Divider Mode, and 1.2V/1.2V

Mode

 Supports QC 3.0 Mode

 Support CDP Mode for USB 2.0 Data

 Line Drop Compensation for 5V Output

 Programmable High-Accuracy Current Limit

 32mΩ Low R

 Input Over-Voltage Shutdown Protection

 Compatible with Buck, Boost, AC/DC

Converters

 Available in a QFN-10 (1.5mmx2mm)

Package

APPLICATIONS

 USB Charging Downstream Port (CDP)

 USB Dedicated Charging Ports (DCP)
