BD2242G-GTR

Description

BD2222G, BD2242G and BD2243G are low 

on-resistance N-channel MOSFET high-side power 

switches, optimized for Universal Serial Bus (USB) 

applications. These devices are equipped with the 

function of over-current detection, thermal shutdown, 

under-voltage lockout and soft-start. Moreover, the 

range of Current limit threshold can be adjusted from 

0.2A to 1.7A by changing the external resistance.
