LM75BIMX-3 from Texas Instruments, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SDA | bidirectional | I2C serial bi-directional data line, open-drain. Requires an external pull-up resistor (or current source) to +VS. Operates up to 400 kHz. |
| 2 | SCL | input | I2C clock input from the bus controller. Requires an external pull-up resistor (or current source) to +VS. Operates up to 400 kHz. |
| 3 | O.S. | output | Over-temperature Shutdown alert output, open-drain (sink up to 10 mA). Requires an external pull-up resistor; asserts when the measured temperature crosses the programmable T_OS limit and releases at T_HYST. Polarity and fault-queue depth are configurable via the configuration register; typically wired to a controller interrupt line. |
| 4 | GND | power_in | Power supply ground / device reference. Connect to system ground. |
| 5 | A2 | input | User-set I2C address input bit A2. Tie to GND for logic 0 or to +VS for logic 1 to select one of eight I2C slave addresses (base address 0x48 = 1001_000x, offset by {A2,A1,A0}). |
| 6 | A1 | input | User-set I2C address input bit A1. Tie to GND for logic 0 or to +VS for logic 1 to select the device's I2C slave address. |
| 7 | A0 | input | User-set I2C address input bit A0. Tie to GND for logic 0 or to +VS for logic 1 to select the device's I2C slave address. |
| 8 | +VS | power_in | Positive supply voltage input, 3 V to 5.5 V (absolute maximum 6.5 V). Decouple with a 100-nF bypass capacitor near the pin plus ~10 µF of bulk capacitance. |
