●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
