USB Charging Port Controller with Current Limit Switch, Supporting CDP, DCP Modes
The EV5030D-QH-00A is an evaluation board for MP5030D, which integrates an USB current limit switch and charging port identification circuit. It achieves 3A continuous output current over a wide input supply range.
With MP5030D, it supports Dedicated Charging Port (DCP) and Charging Downstream Port (CDP) schemes for Battery Charging specification (BC1.2), the divider Mode, 1.2V/1.2V Mode without the need for external user interaction.
MP5030D provides linear line drop compensation, load current detection and status indication.
Fault condition protection includes hiccup current limiting, input OVP and thermal shutdown.
MP5030D requires a minimum number of readily standard external components to complete USB switch and charging mode auto detection solution. MP5030D is available in QFN-10(1.5mmx2mm) package.

USB Charging Port Controller with Load Detection Supporting CDP, DCP Modes
The MP5030D integrates a USB current-limit switch and charging port identification circuitry. The MP5030D achieves 3A of continuous output current over a wide input supply range.
The output of the USB switch is current-limit programmable. The MP5030D supports dedicated charging port (DCP) and charging downstream port (CDP) schemes for battery charging specification (BC1.2), divider mode, and 1.2V/1.2V mode without the need for external user interaction.
The MP5030D provides linear line drop compensation, load current detection, and status indication.
Full protection features include hiccup current limiting, input over-voltage protection (OVP), and thermal shutdown.
The MP5030D requires a minimal number of readily available, standard, external components to complete the USB switch and charging mode auto-detection solution. The MP5030D is available in a QFN-10 (1.5mmx2mm) package.
