LM95221CIMM

Texas Instruments · Temperature Sensors · VSSOP-8

LM95221CIMM from Texas Instruments, in a VSSOP-8. 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 D1+ passive Diode current source connected to the anode of remote diode 1; a 2.2 nF bypass capacitor between D1+ and D1- is recommended, and the pin should be grounded if the thermal diode is not used.
2 D1- passive Diode return current sink connected to the cathode of remote diode 1; a 2.2 nF capacitor is recommended between D1+ and D1-, and the pin should be grounded if the thermal diode is not used.
3 D2+ passive Diode current source connected to the anode of remote diode 2; a 2.2 nF bypass capacitor between D2+ and D2- is recommended, and the pin should be grounded if the thermal diode is not used.
4 D2- passive Diode return current sink connected to the cathode of remote diode 2; a 2.2 nF capacitor is recommended between D2+ and D2-, and the pin should be grounded if the thermal diode is not used.
5 GND power_in Power supply ground.
6 VDD power_in Positive supply voltage input from 3.0 V to 3.6 V, bypassed with a 0.1 µF capacitor in parallel with 100 pF placed as close as possible to the pin, with noise kept below 200 mVp-p.
7 SMBDAT bidirectional SMBus bidirectional data line to and from the controller, implemented as an open-drain output that may require an external pull-up resistor.
8 SMBCLK input SMBus clock input from the controller that may require an external pull-up resistor.
