LTC2945HUD-1#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a low-ESR capacitor for the input capacitor and place it close to the VIN pin.
  • Use a sense resistor with a low temperature coefficient and a high power rating. Ensure the sense resistor is placed close to the IC and the Kelvin connection is used to connect the sense resistor to the IC. Also, calibrate the current measurement by adjusting the offset and gain registers.
  • The maximum cable length for the I2C interface is dependent on the capacitance of the cable and the clock frequency. As a general guideline, a cable length of up to 10 meters is recommended for a clock frequency of 400 kHz.
  • The thermal monitoring feature uses an external thermistor connected to the THERM pin. Choose a thermistor with a suitable beta value and connect it to the THERM pin through a voltage divider. The IC will then monitor the temperature and alert the system if it exceeds the set threshold.
  • The ALERT pin is an open-drain output that asserts low when an alert condition is detected, such as overcurrent, overvoltage, or overtemperature. It can be connected to an interrupt pin of a microcontroller to generate an interrupt when an alert condition occurs.
