Hi Chuck.. Apologize for the delay but tried to do it with a computer software, but failed. I drew it by hand, as I do not want to waste anymore time trying to figure out the various free softwates. (I tried multisim but it did not have all the parts…
Part Number: LM5101C Other Parts Discussed in Thread: LM5101 Hello E2E,
Our customer is using the LM5101CMY for mass produced products. (We know that the LM5101 status is NRND.) Occasionally, when VDD exceeds 13V, the HO pulse is output thinner than…
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…
Part Number: UCC27210 Other Parts Discussed in Thread: LM5101 Hi Team,
I am facing issue with UCC27210 driver output pulses. Below is the schematic.
Vbatt = 12Vdc typical Vgate = 10.5V dc
I tried by reducing the switching frequency till 50Hz.…
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…
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…
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…
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…
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.
Hi Munir,
Thanks for asking about LM5101. I am an apps engineer with this device and will answer.
LM5101 has a CMOS output stage. This info can be found in the datasheet section 9 paragraph 2.
Are you concerned about latchup? Latchup is not a risk…
