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.

Reduce 5.4mW per 1°C above 25°C Caution: Operating the IC over the absolute maximum ratings may damage the IC. In addition, it is impossible to predict all destructive situations such as short-circuit modes, open circuit modes, etc. Therefore, it is important to consider circuit protection measures, like adding a fuse, in case the IC is operated in a special mode exceeding the absolute maximum ratings.
