PI5PD2041B/51B
70mΩ Current-Limited, Power-Distribution Switches
Description
The PI5PD2041B/51B is an integrated 70mΩ N-channel
MOSFET power switches for self-powered and bus-
powered Universal Series Bus (USB) applications. The
devices are equipped with charge pump circuitry to drive
the internal MOSFET switch. The switch’s low R
