5.5V, 2.4A, Low RDS(ON) Load Switch



The MP5075 provides up to 2.4A of load protection over a 3V to 5.5V voltage range with a small RDS(ON) in a space-saving package. The MP5075 is a very high-efficiency and space-saving solution for notebooks, tablets, and other portable and battery-operated applications.
With a fixed soft-start function, the MP5075 can prevent inrush current during circuit start-up. The MP5075 also provides output discharge functions, over-current protection (OCP), and thermal shutdown features. 
The max load at the output (source) is current-limited. This is accomplished by utilizing sense FET topology. 
An internal charge pump drives the gate of the power device, allowing for a very low on-resistance DMOS power FET of just 38mΩ.
The MP5075 is available in a space-saving SOT563 (1.6mmx1.6mm) package.
