L6207PD Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the L6207PD?
  The maximum operating frequency of the L6207PD is 100 kHz, but it can be operated up to 200 kHz with reduced performance.
• How do I choose the right sense resistor value for the L6207PD?
  The sense resistor value depends on the desired current limit and the voltage supply. A general rule of thumb is to choose a sense resistor value that sets the current limit to 1.5 to 2 times the maximum expected current.
• What is the purpose of the bootstrap capacitor in the L6207PD?
  The bootstrap capacitor is used to generate the high-side gate drive voltage. It is charged through the bootstrap diode and discharged through the high-side MOSFET.
• How do I protect the L6207PD from overvoltage and undervoltage conditions?
  The L6207PD has built-in overvoltage and undervoltage protection, but additional external protection circuits can be added to provide extra protection. For example, a voltage supervisor can be used to monitor the input voltage and shut down the device if it exceeds the recommended operating range.
• What is the maximum power dissipation of the L6207PD?
  The maximum power dissipation of the L6207PD depends on the package type and the operating conditions. For the PDIP package, the maximum power dissipation is 1.4 W, while for the PowerSO package, it is 2.5 W.
