Part Number: UCC37322 When VDD is 12V what is the recommended way to drive the Enable pin. Do I need a special driver. Can The ENBL pin pull-up be changed? Please provide some examples if available.
Im planning to use UCC37322 and implement this part…
Hi John,
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…
Hi John,
Glad to hear from you!
Since you're using Vdd = 12V, the IN pin (#2) max is Vdd + 0.3 = 12.3V. Though your waveforms are looking good, it is generally best practice to give yourself some wiggle room and not operate the driver so close to the…
Hello, Drew,
BTW, UCC37322's gate drive current goes through the sense resistor according to the its ground and FET source/ground connection. The strong gate driver can cause a strong noise on the sense resistor.

Hi,
Has the request for the model for this UCC37322 been processed?
If not, what other gate driver already available on TINA-TI possibly comes close to this considering its a 9A driver.
Suggestions please.
Thanks

Hello,
I have attached the following circuit which i have been developing overtime.
The OBJECTIVE is to get as high as possible a current at the gate of the MOSFET (VF1) to achieve faster pulse times of the LED.
