Texas Instruments provides a recommended PCB layout in the application note SLUA623, which includes guidelines for thermal vias, copper pours, and component placement to ensure optimal thermal performance.
The LM95245CIMMX-1/NOPB has a built-in calibration mechanism. Refer to the datasheet section 8.3.1 for the calibration procedure, which involves writing to the CAL_REG register to adjust the temperature offset and gain.
The maximum cable length for the I2C interface depends on the system design and noise environment. As a general guideline, Texas Instruments recommends keeping the cable length below 10 inches (25 cm) to ensure reliable communication. For longer cable lengths, consider using I2C bus repeaters or buffers.
Yes, the LM95245CIMMX-1/NOPB is designed to support hot-swap applications. The device has built-in power-on reset and brown-out detection, which helps ensure reliable operation during power-up and power-down sequences.
The thermal shutdown feature is enabled by default, but can be disabled by writing to the TSD_REG register. When enabled, the device will shut down when the die temperature exceeds the thermal shutdown threshold (typically 150°C). In your system design, ensure that you have a mechanism to detect and respond to thermal shutdown events, such as resetting the device or initiating a cooling sequence.
