●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
1) Low On-Resistance (Typ. 160mΩ) N-channel MOSFET Built-in
2) Over-Current Detection (Output off-latch operation)
3) Thermal Shutdown
4) Open-Drain Fault Flag Output
5) Under-Voltage Lockout
6) Soft-Start Circuit
7) Input Voltage Range: 2.7V ~ 5.5V
8) Control Input Logic
Active-High : BD2220G
Active-Low : BD2221G
9) Reverse Current Protection when Power Switch Off
10) SSOP5 Package
