L9958 Frequently Asked Questions (FAQs)

  • The L9958 can operate from -40°C to 150°C, but the maximum junction temperature (TJ) should not exceed 150°C.
  • The L9958 requires a 3.3V or 5V power supply, and the EN pin should be pulled high to enable the device. Additionally, the CFG pins should be properly configured to select the desired operating mode.
  • The maximum current rating for the L9958's output stages is 1.5A per phase, but this can be increased to 3A with proper heat sinking and thermal management.
  • Check the motor connections, ensure proper configuration of the CFG pins, and verify that the EN pin is properly enabled. Also, check the fault flags (FLT) and the diagnostic registers for error codes.
  • Yes, the L9958 is designed for 3-phase motor control applications and can handle up to 3-phase motors with a maximum current rating of 1.5A per phase.
