ADT7476ARQZ-REEL Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and thermal vias under the package is recommended. This helps to dissipate heat efficiently and reduces thermal resistance.
  • Calibrate the device using the CAL pin, and ensure that the thermal sensor is in close proximity to the device being monitored. Also, use a low-noise, low-impedance connection to the thermal sensor.
  • The maximum cable length is 10 meters (33 feet) for the remote thermal sensor. Exceeding this length may result in signal degradation and inaccurate temperature readings.
  • Yes, the ADT7476 can be used with a fan controller to regulate fan speed based on temperature. The device provides a PWM output that can be used to control fan speed.
  • The ADT7476 provides a THERM output that can be used to detect thermal shutdown and faults. This output can be connected to a microcontroller or other logic to initiate shutdown or alert the user.
