Part Number: UCC21520 Other Parts Discussed in Thread: UCC21550 Hi team,
I have two question need your support:
1. Is the input signal 25Khz 0-3.3V square wave acceptable?
2. Pin 7 is an NC pin, can it be grounded?
Thanks

Part Number: UCC21520 Hi expert,
In the SOP project, my customer found that UCC21520 has a case of abnormal output. Check that the low-voltage side is working normally. The high-voltage side customer has measured the auxiliary power supply current is…
Part Number: UCC21520 Hi supporter,
I used UCC21520 to drive a half-bridge 3-phase MOSFET circuit (control motor), but there are some problems happened.
Firstly, I don't connect the driver UCC21520 to the half-bridge 3-phase circuit. The signal high side…
Part Number: UCC21520 Dear technical support team,
I am developing the 1.2KV voltage switching circuits with UCC21520, which required to achieve dv/dt ramp rate of 40V/ns.
Could you please advise what are the considerations of the high voltage switch…
Part Number: UCC21520 Hi experts,
What does the 'safety margin zone' and 'operating zone' mean? Why the 1800Vrms has better life than 1500V, 254 years than 135 years?
Thanks.

Part Number: UCC21520-Q1 Other Parts Discussed in Thread: ESDS302 , UCC21550 , UCC21520 Hello team,
Have seen references which have schottky diode at the input of INA and INB pins of a gate driver. One is towards GND and one is pulled high to VCC.
Wanted…
Part Number: UCC21520 Hi Team,
My customer is using UCC21520 and meet some issues that need your help.
Issue:
Customer found Vds oscillation, measuring PWM from the DSP and it’s good. But if measuring at INA of UCC21520, found similar oscillation on…

Part Number: UCC21520-Q1 Other Parts Discussed in Thread: UCC21520 Hello team,
This is general question.
I believe the difference between ucc21520-q1 and ucc21520a-q1 is UVLO threshold. (5V vs 8V)
What system is beneficial for non-A and what system is…
