Part Number: ISO5452 Hi team
Our customer is using ISO5452 as IGBT driver in servo, but we found that there is no clarification of DESAT during start up(VCC2 UVLO) in our datasheet, what would happen if IGBT is short already when starting up? Does DESAT…
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 HI T.I Support,
1 - I use the ISO5452 as DESAT protection on IGBT. The IGBT have VCE=5V in 300A and on this current I want to protect. Please advise how to set the application to 9V - (DESAT threshold).
Can I add a Zener diode in…
Part Number: ISO5452 Hi Team,
Our customer is evaluating the ISO5452 in their application, during their test, they found that when there is no HV voltage applied on the IGBTs, we will still see the FLT triggered to low. They want to know if this is the…
Part Number: ISO5452-Q1 Other Parts Discussed in Thread: ISO5452 Hi Ti,
I am performing short circuit type -1 test based on AQG324 standard. I am using an external wire to short the High side switch and using a function generator to give gate pulse to…
Part Number: ISO5452-Q1 Other Parts Discussed in Thread: ISO5852S , ISO5452 Dear team,
I see we have EVM for ISO5852s, so want to double confirm if could change ISO5452 on the EVM board directly? Any where need to change for ISO5852S EVM?
Thanks.
Best regards…
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 Other Parts Discussed in Thread: ISO5451
Hi,
The attachment is the IGBT I used. I didn’t understand very well when designing the ISO5452 pin 2 Desat function, so please help:
1. D4 design considerations, how many volts do I…
Part Number: ISO5452 Dear team,
When customer did short circuit protection test of ISO5452, the IC should be soft shut down under this mode, but customer tested no soft shut down as below picture shows.
Could you kindly help confirm?
Thanks.
Thanks…
