HV9923N3-G Frequently Asked Questions (FAQs)

  • A good PCB layout is crucial for the HV9923N3-G. Ensure a solid ground plane, keep the input and output traces separate, and use a Kelvin connection for the current sense resistor. Refer to Microchip's application note AN2013 for more details.
  • Choose a current sense resistor value that provides an adequate voltage drop across the resistor while keeping power dissipation in mind. A good starting point is 0.1 ohms to 1 ohm. Consult the datasheet and application notes for more information.
  • The maximum allowable voltage on the VCC pin is 18V. Exceeding this voltage may damage the device. Ensure that the voltage regulator or power supply provides a stable voltage within the recommended range.
  • The HV9923N3-G has a built-in overcurrent protection feature. Connect the OC pin to a resistor divider network that sets the overcurrent threshold. The device will shut down when the current exceeds this threshold. Refer to the datasheet for more information.
  • The EN (enable) pin is used to turn the device on or off. Connect the EN pin to a logic signal (e.g., from a microcontroller) to enable or disable the HV9923N3-G. This pin can be used to implement power sequencing or to turn off the device during standby modes.
