BD2244G-M BD2245G-M
General Description
BD2244G-M and BD2245G-M are low on-resistance
N-channel MOSFET high-side power switches,
optimized for Universal Serial Bus (USB) applications.
BD2244G-M and BD2245G-M 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
