Overview
Datasheet 1 Channel Compact High Side Switch ICs 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.
