The

is an integrated 200mΩ power

switch

for

self-powered

and

bus-powered

Universal Series Bus (USB) applications. Its low

quiescent supply current (50μA) and small

package (SOT-23-5) is particularly suitable in

battery-powered portable equipment.

Several protection functions include soft start to

limit inrush current during plug-in, current limiting

at 0.8A(VIN=3.0V) and thermal shutdown to

protect damage under over current conditions.
