1.7V- 5.5V, Ultra- Small, Single-Channel 2A Current-Limited Power Distribution Switch with Output Discharge



The MP62040/MP62041 Power Distribution Switch is designed for high-side load switch. The switch operates from 1.7V to 5.5V nominal input voltage and includes an 85mΩ power MOSFET to handle up to 2A continuous load.  The MP62040/MP62041 has slew rate control with 115μs rising time to limit inrush current when enabling the switch.  The built-in level shift function allows a logic signal on enable input that may be different from the supply voltage to switch the high side P-channel MOSFET ON or OFF.  The MP62040/MP62041 is available in an ultra-small UTQFN4 package, with ultra-low height (0.55mm typ).
