BD2224G and BD2225G are low on-resistance N-channel MOSFET high-side power switches, optimized for Universal Serial Bus (USB) applications.
The BD2224G and BD2225G are low‑on‑resistance N‑channel MOSFET high‑side power switches designed for USB and memory‑card applications. They integrate over‑current detection, thermal shutdown, under‑voltage lockout and soft‑start functions, and are offered in a 5‑lead SSOP package.
The document provides absolute maximum ratings, operating conditions, electrical characteristics, pin configuration, timing diagrams, waveform data and ordering information for both device variants.
| Typical On‑Resistance (Ron) | 150 mΩ |
|---|---|

| Over‑Current Threshold (ITH) typical | 780 mA |
| UVLO Threshold (typical) | 2.3 V |
| Package | SSOP5 |
| Supply Voltage Rating | -0.3 V to 6.0 V |
| Enable Input Logic | Active‑High (BD2224G), Active‑Low (BD2225G) |
The typical on‑resistance is 150 mΩ.
They operate from 2.7 V up to 5.5 V.
An open‑drain low‑level fault flag is output on the /OC pin.
It prevents the switch from turning on until VIN exceeds 2.3 V and shuts it off if VIN falls below 2.2 V.
