Maxim Integrated DS2482X-101+T, Bridge 1-Wire® to I²C, 9-WFBGA/WLBGA package, 2.9V to 5.5V supply, 750µA supply current, -40°C to 85°C operating temperature.
| Parameter | Value |
|---|---|
| Supply voltage | 2.9V ~ 5.5V |
| Current - supply | 750µA |
| Protocol | 1-Wire® |
| Interface | I²C |
| Operating temperature | -40°C ~ 85°C |
| Package | Tape & Reel (TR); Cut Tape (CT) |
| Function | Bridge, 1-Wire® to I²C |
| Case | 9-WFBGA, WLBGA |
It lets a standard I²C master communicate with 1-Wire slaves — temperature sensors, EEPROMs, battery monitors — without bit-banging the protocol in firmware. The bridge handles the 1-Wire timing and device addressing internally, so the host just writes and reads registers over I²C.
ROHS3 compliant, no lead or halogen restrictions to worry about for EU or China RoHS.
The DS2482X-100 is the same I²C-to-1-Wire bridge in a larger 8-SOIC package. The DS2482X-101+T shrinks to a 9-WLP (1.53x1.53 mm) for space-constrained designs — same function, different footprint and rework process.
Yes — the 2.9V to 5.5V supply range includes 3.3V, so it works directly on a 3.3V I²C bus without level shifting.
