General Description
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.
Features

■ Flag Output Delay
■ Under-Voltage Lockout
■ Soft-Start Circuit
■ Control Input Logic
 Active-High : BD2220G
 Active-Low : BD2221G
■ Reverse Current Protection when
Power Switch Off
Applications
USB hub in consumer appliances, PC, PC peripheral
equipment, and so forth
