LTC4292IUJ#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 short, wide traces for power and ground connections.
  • Use a low-impedance current sense resistor (e.g., 1 mΩ) and place it close to the IC. Ensure the sense resistor is in the same thermal zone as the IC. Use a Kelvin connection to the sense resistor to minimize errors.
  • The maximum allowed voltage on the VCC pin is 5.5V. Exceeding this voltage can damage the IC. Ensure the power supply voltage is regulated and within the recommended operating range.
  • Set the current limit by programming the ILIM pin with a resistor to the VCC pin. The current limit is calculated using the formula: I_LIM = (VCC - 0.5) / R_ILIM. Choose a suitable resistor value to achieve the desired current limit.
  • The FAULT pin is an open-drain output that indicates an overcurrent or overtemperature fault condition. It can be used to trigger a system shutdown or alarm in the event of a fault.
