Using the MC34GD3000 Gate Driver with a 24 V BLDC Motor

Hello,

I am currently using the S32K144 BLDC/PMSM Development Kit, which includes the MC34GD3000 gate driver IC.

From the application circuit and documentation, it appears that the reference design is intended for a 12 V BLDC motor. However, the BLDC motor included with the development kit is actually a 24 V motor, which raised a few questions for me.

I would appreciate your advice on the following:

My understanding is that the MC34GD3000 gate driver itself operates from a 12 V gate-drive supply, while the inverter DC bus can be supplied with 24 V for driving a 24 V BLDC motor. Is this the correct way to use the MC34GD3000, or am I missing something?
Are there any voltage-related limitations or precautions when using the MC34GD3000 with a 24 V BLDC motor? For example, are there any recommended operating conditions, bootstrap considerations, or other design points that I should pay attention to?
If anyone has experience using this development kit or the MC34GD3000 with a 24 V motor, I would greatly appreciate your advice.

Thank you in advance!
