L6201 datasheet by STMicroelectronics

L6201 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the L6201?
  The maximum operating frequency of the L6201 is 200 kHz, but it can be operated at higher frequencies with reduced performance.
• How do I choose the right sense resistor value for my application?
  The sense resistor value depends on the maximum current and voltage of your application. A general rule of thumb is to choose a sense resistor value that results in a voltage drop of around 0.5-1.5 V at the maximum current.
• What is the purpose of the bootstrap capacitor (CB) in the L6201?
  The bootstrap capacitor (CB) is used to generate the high-side gate drive voltage. It is charged through the bootstrap diode (DB) and the voltage regulator (VREG) when the low-side switch is on.
• How do I protect the L6201 from overcurrent and overvoltage conditions?
  The L6201 has built-in overcurrent protection, but it's still recommended to add external protection circuits, such as fuses or PTC resistors, to protect against overcurrent and overvoltage conditions.
• Can I use the L6201 in a synchronous rectification configuration?
  Yes, the L6201 can be used in a synchronous rectification configuration, but it requires additional external components and careful design to ensure proper operation.
