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…
Part Number: ISO5452-Q1 Other Parts Discussed in Thread: TINA-TI , ISO5452 Tool/software: TINA-TI or Spice Models Is it possible to simulate ISO5452 from TI in TI TINA? ISO5452 has an IBIS model.
Part Number: ISO5452-Q1 Hi Team,
Either UVLO1 or UVLO2 occurs, the RDY pin output goes low. What about the FLT Pin behaviors under UVLO1 or UVLO2?
And when desaturation is active, the RDY will go low and then go high, does this design to prevent FLT is…
Part Number: ISO5452-Q1 Hi E2E,
1 I have check the datasheet and I don't find the equation to calculate the DESAT time. Did I get something wrong?
2 The clamp pin is not used , is this pin suspended?
3 I have a question that we need big source current…
Part Number: ISO5452-Q1 Other Parts Discussed in Thread: TINA-TI , , ISO5451 Tool/software: TINA-TI or Spice Models Hi,
Could you please send me the Pspice Model of ISO5452-Q1, wayne.liu@ti.com Thanks.
Part Number: ISO5452-Q1 Other Parts Discussed in Thread: ISO5452 , I'm working on an application which requires a 2.5V desat threshold with 2us blanking time. I'd ideally like to use a Zener diode to set the threshold as I would otherwise need a very large…
Part Number: ISO5452-Q1 Hi,
My customer would like to connect RDY and FLT together to save MCU GPIO, so in this case, when FLT is set to 0, can we pull RST low and make FLT goes back to high and the chip goes back to normal? Because Datasheet Figure 46…
Hi Zoe,
The main differences between the ISO5452 DESAT-pin and the UCC21732 OC-pin is the detection voltage threshold of the internal comparator and the current source.
DESAT-pin
9V threshold voltage
Short circuit protection is engaged when the DESAT…
Part Number: ISO5452-Q1 Hello, Is it fine to add pull up to the DESAT, to increase the current flow to get a lower over current detection limit? Best regards, Anton
Part Number: ISO5452-Q1 Other Parts Discussed in Thread: ISO5452 , UCC21520 Hello,
For the ISO5452, can I drive the RESET pin with an active low signal to disable the outputs? I have windowed comparators that trigger for overcurrent events on the 3 phases…
