BD2232G and BD2233G are low on-resistance N-channel MOSFET high-side power switches, optimized for Universal Serial Bus (USB) applications. They are equipped with the function of over-current detection, thermal shutdown, under-voltage lockout and soft-start.
This technical note describes the BD2232G and BD2233G N‑channel MOSFET high‑side power switches, optimized for USB applications. It lists features such as low on‑resistance, over‑current detection, thermal shutdown, under‑voltage lockout, and soft‑start, and provides the functional block diagram and pin configuration.
The document includes absolute maximum ratings, operating conditions, electrical characteristics, measurement circuits, timing diagrams, and ordering information. It also outlines the operation of the thermal shutdown, over‑current detection, and UVLO circuits, and gives typical performance graphs for various parameters.
| Typical On‑Resistance (Ron) | 100 mΩ |
|---|---|
| Input Voltage Range | 2.7 V ~ 5.5 V |
| Operating Temperature | -40 °C ~ 85 °C |
| Supply Voltage Rating (VIN) | -0.3 V ~ 60 V |
| Over‑Current Threshold (ITH) | Typical 1275 mA |
The typical on‑resistance is 100 mΩ.
It operates from 2.7 V to 5.5 V.
UVLO activates when VIN exceeds about 2.3 V (typical) and shuts off when VIN falls below about 2.2 V (typical).
