BD2242G
1ch Adjustable Current Limit High Side Switch IC

BD2242G and BD2243G are low on-resistance N-channel MOSFET high-side power switches, optimized for Universal Serial Bus (USB) applications.
BD2242G and BD2243G 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 200mA to 1.7A by changing the external resistance.
