General Description
This is the product guarantees long time support in
Industrial market.
BD2220G and BD2221G are low on-resistance
N-channel MOSFET high-side power switches,
optimized for Universal Serial Bus (USB) applications.
BD2220G and BD2221G are equipped with the function
of over-current detection, thermal shutdown,
under-voltage lockout and soft-start.
