MC33982CHFK datasheet by Freescale Semiconductor

MC33982CHFK Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the MC33982CHFK?
  The maximum operating temperature range for the MC33982CHFK is -40°C to 125°C.
• How do I configure the device for low-power mode?
  To configure the device for low-power mode, set the EN pin low and the VREG pin high. This will reduce the quiescent current to approximately 10 μA.
• What is the recommended PCB layout for the MC33982CHFK to minimize EMI?
  To minimize EMI, it is recommended to use a 4-layer PCB with a solid ground plane, and to keep the high-current paths short and direct. Additionally, use a common-mode choke and a shielded inductor to reduce radiated emissions.
• How do I protect the device from overvoltage and undervoltage conditions?
  To protect the device from overvoltage and undervoltage conditions, use a voltage supervisor or a reset IC to monitor the input voltage and reset the device if it falls outside the recommended operating range.
• What is the maximum current rating for the output stage of the MC33982CHFK?
  The maximum current rating for the output stage of the MC33982CHFK is 2.5 A per channel, with a maximum total current of 5 A.
