LM94021BIMG Frequently Asked Questions (FAQ)

  • Texas Instruments recommends a 2-layer or 4-layer PCB with a solid ground plane on the bottom layer to minimize thermal resistance. The device should be placed near a thermal pad or a heat sink to dissipate heat efficiently.

  • To ensure accurate temperature measurement, it is essential to calibrate the device using the CAL pin. The CAL pin should be connected to a precision voltage source, and the device should be calibrated at multiple temperature points to account for any non-linearity.

  • The maximum cable length for the remote temperature sensing feature depends on the cable type and the noise environment. As a general guideline, Texas Instruments recommends keeping the cable length below 10 meters to minimize noise and ensure accurate temperature measurement.

  • Yes, the LM94021BIMG is designed to operate in high-vibration environments. However, it is essential to ensure that the device is properly secured to the PCB and that the PCB is rigid enough to withstand the vibrations. Additionally, the device should be tested under vibration conditions to ensure reliable operation.

  • During power-up, the thermal shutdown feature may be triggered if the device is exposed to high temperatures. To handle this, it is recommended to implement a power-up sequence that slowly ramps up the voltage to the device, allowing it to stabilize before enabling the thermal shutdown feature.
