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
Features AEC-Q100 Qualified Adjustable Current Limit Threshold: 200mA to 1.7A Built-in Low On-Resistance (Typ 100mΩ) N-channel
MOSFET Built-in Soft-Start Circuit Output Discharge Function Open-Drain Fault Flag Output Thermal Shutdown Under-Voltage Lockout Reverse Current Protection when Power Switch Off Control Input Logic
