UCC5881-Q1: Gate Driver Power Requirement

TI-CSC
Genius 12885 points
Part Number: UCC5881-Q1
Other Parts Discussed in Thread: UCC14241-Q1,

Tool/software:

Hello E2E Experts,

Good day.

I am currently utilizing the UCC5881-Q1 gate driver for a two-level voltage source inverter design. For the corresponding power supply, I have selected the UCC14241-Q1 IC.

I would appreciate your guidance on how to accurately calculate the total power consumption of all six gate drivers. This will enable me to appropriately size the 24V power supply required for the system.

Below is the schematic.

Kindly note that the gate driver board has been designed for a two-level voltage source inverter configuration, which includes a total of three high-side gate drivers and three low-side gate drivers.

For your reference, the gate charge of the MOSFETs used is 660 nC, and the switching frequency is 70 kHz.

Regards,

TICSC

    Hi,

    Details about this device are protected under NDA and cannot be disclosed on the public forum.

    You may reach out to me via email or through a private message on E2E, where I can then confirm that an NDA is in place and provide support.

    Regards,
