Monolithic Power Systems, Inc. Power Distribution Switches, Load Drivers MP5030CGQH-Z

The MP5030CGQH-Z is a USB current-limit switch and charging port controller that integrates a charging port identification circuit. It supports a continuous output current of up to 3A and operates over a wide input voltage range of up to 14V. The device is capable of handling various charging modes, including Dedicated Charging Port (DCP), Charging Downstream Port (CDP), and Quick Charge (QC) 2.0/3.0, without requiring external user interaction. The MP5030CGQH-Z features programmable current limiting, linear line drop compensation for 5V outputs, and includes full protection mechanisms such as hiccup current limiting, input over-voltage protection, and thermal shutdown. It is designed to work with a minimal number of external components, making it suitable for applications in USB charging systems. The product is housed in a compact QFN-10 package measuring 1.5mm x 2mm, which is advantageous for space-constrained designs.
