MC33978AEKR2 Frequently Asked Questions (FAQs)

  • The maximum current rating of the MC33978AEKR2 is 2.5A per channel, with a maximum total current of 5A.
  • The MC33978AEKR2 can be configured for high-side or low-side switching by connecting the VCC pin to the desired voltage rail and configuring the EN pin accordingly. Refer to the application note AN4836 for more details.
  • The diagnostic pins (nD1 and nD2) on the MC33978AEKR2 provide fault detection and diagnostic capabilities, such as overcurrent, overtemperature, and undervoltage detection.
  • The MC33978AEKR2 has built-in overcurrent protection, which can be enabled by connecting a sense resistor to the IS pin. The device will limit the current to the programmed value when an overcurrent condition is detected.
  • The thermal resistance of the MC33978AEKR2 package is 25°C/W (junction-to-ambient) and 10°C/W (junction-to-case).
