Hi Zoe,
The main differences between the ISO5452 DESAT-pin and the UCC21732 OC-pin is the detection voltage threshold of the internal comparator and the current source.
DESAT-pin
9V threshold voltage
Short circuit protection is engaged when the DESAT…
Hi Anand,
Theoretically, it should not be an issue if all the FETs and gate resistors have the exact same parameters. However in real life they are never completely the same, and the FETs are placed at different places on the PCB so the different parasitic…
Part Number: UCC21732-Q1 Other Parts Discussed in Thread: UCC21732
How could we understand the MAX of output voltage?
Is this spec tested or calculated?
Is it refers to OUTMAX=VDDA+0.5 or OUTMAX= 30+0.5?
If this spec is a test result? What kind of voltage…
Part Number: UCC21732-Q1 Dear team,
My customer uses our 6pcs UCC21732-Q1 in their traction inverter projects. Recently they found a problem, there is oscillation at FLT pin. Below is their schematic, and 6pcs UCC21732-Q1 have the same schematic. The…
Part Number: UCC21732 Hello Experts
I am using Synchronous rectification at the PSFB secondary side where the load current flow is from source to drain. So my doubt is whether this ucc21732 can be used for getting of desat protection ?
Thanks and re…
Part Number: UCC21732-Q1 Hi,
Good Day.
I am trying to access application notes from your website, but this does not open.

Part Number: UCC21732 Hello team,
If I don't want to use the CLMPE pin of UCC21732, Is it recommended to leave it unconnected or connect it to ground or COM?
In LTspice I could see the output only if it is connected to COM.
Best regards,

Part Number: UCC21732 Hello TI Support Team, we are using the UCC21732 gate drivers for a high power inverter (1000VDC, 500Arms) and have problems with dubious error signals RDY and /FLT. A. In case of the RDY (UVLO) signal we already see at 500VDC and…
