LTC2991CMS#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate analog ground plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a low-ESR capacitor for the VCC bypass and place it close to the VCC pin.
  • Calibration involves trimming the internal voltage reference and current sense amplifier gains. Use the CAL pin to adjust the voltage reference and the ISENSE pin to adjust the current sense amplifier gain. Refer to the datasheet for the calibration procedure.
  • The maximum cable length depends on the wire gauge and the sense current. As a rule of thumb, use a 20 AWG wire for up to 10 feet of cable length. To compensate for voltage drops, use a 4-wire Kelvin connection and add a sense resistor (Rs) in series with the sense line.
  • Use the OV and UV pins to detect overvoltage and undervoltage conditions. The OV pin goes high when the input voltage exceeds the overvoltage threshold, and the UV pin goes low when the input voltage falls below the undervoltage threshold. Use these signals to trigger external circuitry to protect the system.
  • Power up the VCC pin first, followed by the VIN pin. Ensure that the VCC pin is stable before applying the VIN voltage. This sequence prevents latch-up and ensures proper device operation.
