LM56CIMMX

Texas Instruments · Temperature Sensors · VSSOP-8

LM56CIMMX 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 VREF power_in 1.250V bandgap voltage reference output that should source a 50 µA load to maintain trip point accuracy.
2 VT2 input Input for the temperature trip point voltage for OUT2, within GND to V+ − 1 V.
3 VT1 input Input for the temperature trip point voltage for OUT1, within GND to V+ − 1 V.
4 GND power_in Ground pin.
5 VTEMP output Temperature sensor output of +6.20 mV/°C x T + 395 mV with a maximum output impedance of 1500 Ω.
6 OUT2 output Open collector active-LOW digital output that goes LOW above the T2 set point and HIGH below T2 − 5°C, not intended to directly drive a fan motor.
7 OUT1 output Open collector active-LOW digital output that goes LOW above T1 and HIGH below T1 − 5°C, not intended to directly drive a fan motor.
8 V+ power_in Positive supply voltage pin, 2.7V to 10V, to be bypassed with a 0.1 µF capacitor to ground.

CAD (KiCad official)

  • Symbol: LM56CIMMX
  • Footprint: Package_SO:VSSOP-8_2.3x2mm_P0.5mm
  • 3D model: VSSOP-8 (KiCad packages3D, STEP)
  • 3D model files: lm56cimmx-etched.step / lm56cimmx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm56cimmx.step / lm56cimmx.glb are the bare package body.
