TMP411BQDGKRQ1 from Texas Instruments, in a VSSOP-8-0.65mm. 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 | V+ | power_in | Positive supply, 2.7 V to 5.5 V for the TMP411-Q1 (recommended operating range 2.7 V to 5.5 V, typical 3.3 V). |
| 2 | D+ | input | Analog input connected to the positive terminal of the remote temperature sensor (diode-connected or transistor-connected BJT); absolute maximum for pins 2 and 3 is -0.5 V to (V+) + 0.5 V on the older die and -0.5 V to 2 V on the newer die. |
| 3 | D− | input | Analog input connected to the negative terminal of the remote temperature sensor; absolute maximum for pins 2 and 3 is -0.5 V to (V+) + 0.5 V on the older die and -0.5 V to 2 V on the newer die. |
| 4 | THERM | output | Active-low open-drain thermal flag that requires a pull-up resistor to V+; input voltage absolute maximum is -0.5 V to 6 V on the newer die and sink current is 6 mA at 0.4 V. |
| 5 | GND | power_in | Ground reference for the device. |
| 6 | ALERT/THERM2 | output | Active-low open-drain alert output (reconfigurable as a second THERM flag) that requires a pull-up resistor to V+; sink current is 6 mA at 0.4 V. |
| 7 | SDA | bidirectional | Open-drain SMBus/I2C serial data line that requires a pull-up resistor to V+; input voltage absolute maximum is -0.5 V to 6 V on the newer die. |
| 8 | SCL | input | Open-drain SMBus/I2C serial clock input that requires a pull-up resistor to V+; input voltage absolute maximum is -0.5 V to 6 V on the newer die. |
