1ch Adjustable Current Limit High Side Switch ICs - BD2222G

BD2222G is low on-resistance N-channel MOSFET high-side power switch, optimized for Universal Serial Bus (USB) applications. This device is 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.

* This product is a STANDARD grade product and not recommend for on-vehicle devices.
