Hello Vaibhav,
I'm glad to hear that the LM5101 is working for you. If you decide to pursue the UCC27210 again, feel free to continue this thread.
best,

Hello, I borrowed the LM5101 from a customer and obtained waveforms. When VDD rises above 13.5V, the output pulse becomes thinner than the input pulse. I think that this operation is not normally. Could you explain about cause for it? Regards, ACGUY LM5101…
Hi Sir,
Thank you for your reply. In Lm5101 datasheet page no 7 ,figure 2, showing 4.4nF load at 300 KHz IDD current approximately 20mA. What it tells either maximum IDD current?
From datasheet LM5101 WSON 10 package thermal resistance 40 deg/W. We are…
Hi Ralf,
As far as I can see, it should work for 48V.
To be double sure, you may want to consult experts on LM5101 for its suitability for such new applications. To do that you can simply make a copy of this thread and only change the part number to LM5101…
Hi Art,
By braking, do you mean setting both outputs low? Yes, the DRV8701E and DRV8701P can do this, but cannot operate at 100 - 130V.
If you need 100 - 130V, you probably need high voltage gate drivers like the LM5101.
Another option is to use two half…
Hi Kubendran,
As you stated, the driver IC input gate pulse from LM5041 found is normal, therefore it seems the issue appears at the driver circuit.
I'd like confirmed again that if the driver IC is LM5101? and are the input signal HI and LI normal? and…

Hi, Jeff
Thank you for your support.
The LM5101 circuit diagram
LM5101 test conditions are as follows:
Input=(10~80)V, Output=(0~80)V, LM5101 VDD=12V
Describe.: LM5101(5&6) pin is set to low level. Test LM5101 Pin3 (HO) is high. Test result cannot…
Hi Richard,
Thanks for the update. I had done the simulation using LM5100 PSpice model, in which the gate driver is not working with 3.3V input signal. I missed to read the threshold voltages of LM5101 family. Thanks for your information.
Dear Johny, LM5101 or LM5102 is recommend to co-work with LM5041 for buck gate driver which can program delay time. You can refer to LM5041EVAL reference design. Thanks
