TMP1075DSGT from Texas Instruments, in a WSON-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | SDA | bidirectional | Serial data line; open-drain output that requires a pullup resistor. |
| 2 | SCL | input | Serial clock input for the I2C and SMBus interface. |
| 3 | ALERT | output | Overtemperature alert; open-drain output that requires a pullup resistor. |
| 4 | GND | power_in | Ground reference pin. |
| 5 | A2 | input | Address select A2: connect to GND or V+ (pin is not available on TMP1075N). |
| 6 | A1 | input | Address select A1: connect to GND, V+, SDA, or SCL (pin is not available on TMP1075N). |
| 7 | A0 | input | Address select A0: connect to GND, V+, SDA, or SCL. |
| 8 | V+ | power_in | Supply voltage, 1.7 V to 5.5 V for TMP1075. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
