1ch Adjustable Current Limit
High Side Switch ICs
BD2222G BD2242G BD2243G
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.
