HIP4081AIB - Renesas Electronics

Description: The HIP4081A is a high frequency, medium voltage Full Bridge N-Channel FET driver IC, available in 20 lead plastic SOIC and DIP packages. The HIP4081A can drive every possible switch combination except those which would cause a shoot-through condition. The HIP4081A can switch at frequencies up to 1MHz and is well suited to driving Voice Coil Motors, high-frequency switching power amplifiers, and power supplies. For example, the HIP4081A can drive medium voltage brush motors, and two HIP4081As can be used to

HIP4081AIB Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout in the HIP4081AIB application note (Renesas document number: R01DS0243EJ0100) that includes guidelines for thermal vias, copper pours, and component placement to minimize thermal resistance and ensure reliable operation.
  • The input capacitors should be selected based on the input voltage ripple, output current, and operating frequency. Renesas recommends using low-ESR capacitors with a voltage rating of at least 1.5 times the maximum input voltage. The application note provides a detailed capacitor selection guide.
  • The maximum allowed output inductor saturation current is not explicitly stated in the datasheet, but it is recommended to keep the inductor saturation current below 1.5 times the maximum output current to ensure reliable operation and prevent inductor damage.
  • The HIP4081AIB has a built-in OCP feature that can be enabled by connecting the OCP pin to a resistor and capacitor network. The application note provides a detailed OCP implementation guide, including calculation formulas for the resistor and capacitor values.
  • The recommended startup sequence is to first apply the input voltage, then the enable signal (EN), and finally the clock signal (CLK). This sequence ensures that the device powers up correctly and prevents unwanted oscillations.
