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 RDS(on),

Note:
(1)Stresses greater than those listed under MAXIMUM
RATINGS may cause permanent damage to the device.
This is a stress rating only and functional operation of the
device at these or any other conditions above those
indicated in the operational sections of this specification
is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect reliability.
(2)All voltages are with respect to GND.
