TMP431BDGKR

Texas Instruments · Temperature Sensors · VSSOP-8-0.65mm

TMP431BDGKR 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 power supply input, specified at 2.7 V to 5.5 V.
2 DXP input Analog positive connection to the remote temperature sensor diode.
3 DXN input Analog negative connection to the remote temperature sensor diode.
4 THERM output Digital thermal flag, active low, open-drain; requires a pullup resistor to V+.
5 GND power_in Ground reference for the device.
6 ALERT/THERM2 output Digital alert output, reconfigurable as a second thermal flag (THERM2), active low, open-drain; requires a pullup resistor to V+.
7 SDA bidirectional Bidirectional SMBus serial data line, open-drain; requires a pullup resistor to V+.
8 SCL input SMBus serial clock line, open-drain; requires a pullup resistor to V+.
