UCC37321: UCC37321, UCC37322 max "in" pin voltage
Part Number: UCC37321
Dear TI experts,
I want to make 2x ucc37321 being in parallel that is connected directly to eachother pin for pin in order to enlarge the output current , Is that ok ?

My name is Mamadou Diallo, I am an applications engineer in the high power drivers group.
Have considered using UCC37321 along with current buffers at its output to meet your current requirement need? This may be also an alternative cost effective solution that you may find helpful in your design.
Let me know your thought.
Please let us know if you require further assistance or press the green button if this helped address your concerns.
In reply to Mamadou Diallo:
Thanks for getting back to me.
1. Section 3.2 of the copied app note discusses limitations of the MOSFETs pairs.
2. The output current of the non-inverting buffer pairs will be dependent on the VDD supply and the total impedance of the turn-on path.
Another important factor to note is to ensure that C3 and current buffer must be placed very close to the MOSFET being driven to reduce the loop of the peak currents path.
Please let me know if you have further questions or press the green button if this helped address your concerns.
