MC34129D Frequently Asked Questions (FAQ)

  • The recommended operating voltage range for the MC34129D is 10V to 18V, with a typical voltage of 12V.

  • To ensure proper heat-sinking, use a heat sink with a thermal resistance of 1°C/W or less, and apply a thin layer of thermal interface material between the device and heat sink. Also, ensure good airflow around the heat sink.

  • The maximum output current of the MC34129D is 1.5A per channel, with a total maximum output current of 3A for both channels.

  • Use voltage regulators or overvoltage protection (OVP) circuits to prevent voltage exceeding 20V or dropping below 8V. Also, consider adding undervoltage lockout (UVLO) circuits to prevent operation below 8V.

  • The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage for the internal power MOSFETs. It should be a low-ESR capacitor with a value between 100nF to 1uF.
