UCC27714: About 4A Peak Output

Guru 21045 points
Part Number: UCC27714

Hi Team,

 

I understand that “4A peak Output ” is HO and LO total current.

(I referred to "IOUT of Absolute Maximum Ratings" and "IGPK of OUTPUT BLOCK".)

 

-OK case: HO peak output current is 4A, LO peak output current is 0A (Total 4A peak output and PW <100ns)

-OK case: HO peak output current is 2A, LO peak output current is 2A (Total 4A peak output and PW < 10us)

-NG case: HO peak output current is 3A, LO peak output current is 3A (Total 6A peak output)

 

Is my understanding correct?

  • Hello Hide,

    The UCC27714 driver HO and LO outputs are rated at 4A typical on each channel. Each driver output is capable of the 4A peak output even if both outputs are active at the same time. There is a limitation of the average, or DC current of 250mA on each output, which is usually not a concern when switching MOSFET Vgs as the peak gate currents are very low duty cycle.

    Confirm if this addresses your questions, or you can post additional questions on this thread.
