Part Number: ISO5452 Gentlemen,
I'm working on a three level Neutral point clamp (NPC) inverter for a motor drive and using the ISO5452 driver chip. The inverter is comprised of SiC mosfets/diodes.
I seem to be getting an erroneous DSAT trip when…
hi,
Thanks for your question.
It is not to drive seperate devices, it is to drive one IGBT/FET. Internally, the pull-up portion of the driver consists of NMOS (& PMOS for TI's gate driver) that sources current to the IGBT/FET gate, and the pull…
Part Number: ISO5452-Q1 Other Parts Discussed in Thread: ISO5452 Hello TI
I have a question about ISO5452 want to verify with you.
In the datasheet, we can see I(OUTH) max is 2.7A, but in our design may be a little over this value, we want to know…
Part Number: ISO5452-Q1 Hello all,
I am using the Pspice model given in the website. I am using the .lib file to run my simulation in Simetrix. But I am not able to get the output. Please suggest sllm445.zip
Part Number: ISO5452 Hi Experts,
Our customer is evaluating for our ISO5452 device in their design, and they are having some questions about the OUTH and OUTL pin connection:
1. in our datasheet, we demonstrated OUTH and OUTL connected with a gate…
Part Number: ISO5452 Dear Audrey,
I have tested the IC - ISO5452 along with IGBT - SKM150GB12T4.
Following is the details as mentioned below:-
Vp = 15V.
Vn = -6.8V.
Rg = 1.2 ohm.
I have shown the image of Vge below:-
There is slight dip…
Part Number: ISO5452 HI,
There is big difference on the time at fall time 90% -> 10% between DESAT function and propagation delay of OUTH to OUTL.
Is the above caused by Cload.?
If yes, where does Cload indicate ?
Customer’s requirement for…
Part Number: ISO5452 Customer was concerned about 9V of the DESAT threshold voltage of ISO5452, since they are afraid the short circuit current might go up a lot until the voltage reaches up to 9V. I believed it should be okay if using a small capacitor…
Part Number: ISO5452-Q1 Is there a more detailed description of subject 10.2.2.6 & Figure 54 of the datasheet. I cannot follow the description in this section. As well I do not see how the description (e.g. "IN+ is also applied to RST") is doen in teh…
