ACST8-8CT Frequently Asked Questions (FAQ)

  • STMicroelectronics recommends a thermal pad on the bottom of the package, connected to a large copper area on the PCB to dissipate heat efficiently. A minimum of 2oz copper thickness is recommended.

  • To ensure accurate temperature measurement, it's essential to calibrate the device using the calibration coefficients provided by STMicroelectronics. Additionally, the device should be mounted in a way that minimizes thermal gradients and ensures good thermal coupling to the target temperature.

  • Although the datasheet specifies a maximum VDD voltage of 5.5V, it's recommended to limit the voltage to 5V to ensure reliable operation and prevent damage to the device.

  • Yes, the ACST8-8CT is designed to withstand high-vibration environments. However, it's essential to ensure that the device is properly mounted and secured to the PCB to prevent mechanical stress and damage.

  • To troubleshoot communication issues, check the I2C bus voltage levels, clock frequency, and signal integrity. Ensure that the device is properly addressed and that the I2C bus is not overloaded. Also, verify that the device is not in a reset or sleep mode.
