Hi everyone
Good day~
I don't know the differences between TLE5028C-XAI & TLE5028C-XAA from the datasheet.
The following is my opinion, I don't know if it is correct:
TLE5028C-XAI-D28 CW 90us, CCW 45us
TLE5028C-XAA-D28 CW 45us, CCW 90us
Or is there a better description different from the datasheet?
Best Regards
Rsiigod

Hi @rsiigod ,
From the description mentioned we can't infer that their output types can't be different.
For TLE5028C-XAA-D28 and TLE5028C-XAI-D28 their operation and outputs are defined as given in datasheet and given in above discussion.
Thanks and regards,
Yashraj

Hi @rsiigod ,
The product TLE5028-XAA-D28 is discontinued.
The I in the TLE5028-XAI-D28 refers to inverted protocol, described in following diagram.
Thanks and regards,
Yashraj

Hi @Yashraj_P
Good day~
I don't understand the meaning of the picture above...
The following is my opinion, I don't know if it is correct:
TLE5028C-XAI-D28 CW 90us, CCW 45us
TLE5028C-XAA-D28 CW 45us, CCW 90us
Does the picture above mean what I think?

Hi @rsiigod ,
The backward pulse duration is 90us and forward pulse duration is 45us,
For inverse types, "CCW rotational direction is emitted as backward pulse at the signal output. CW rotational direction is emitted as forward pulse at the signal output"
So following is the understanding.
TLE5028C-XAA-D28 CW 90us, CCW 45us
TLE5028C-XAI-D28 CW 45us, CCW 90us

Good day~
So following is the understanding.
TLE5028C-XAA-D28 CW 90us, CCW 45us
TLE5028C-XAI-D28 CW 45us, CCW 90us
-----------------------------------------------------------------------
I am more confused....
Normal use the CW output is 45us, So TLE5028C-XAA-D28, CW output should is 45us.
Then inverse type, TLE5028C-XAI-D28, CW output should is 90us.
Is my understanding correct?

Hi @rsiigod ,
No.
As I have mentioned in my previous answer for the inverse types [TLE5028C-XAI-D28], "CCW rotational direction is emitted as backward pulse at the signal output. CW rotational direction is emitted as forward pulse at the signal output". Its opposite for non-inverse [TLE5028C-XAA-D28] types.
Thanks and best regards,

Counter Clock Wise (CCW) rotational direction is emitted as forward pulse at the signal output.
Clock Wise (CW) rotational direction is emitted as backward pulse at the signal output.
So TLE5028C-XAA-D28 CW 90us, CCW 45us
But....
Figure 8 is CW direction, output forward pulse 45us for TLE5028C-XAA-D28.
This is exactly what puzzles me!!!!
Is there any mistake? Figure 8? or the above description?
As far as I know TLE5028C is improved based on TLE5027C.
So it should be the same output pattern?
So the "inverse type" output should be CW output is 90us, CCW output is 45us.

Hi @rsiigod ,
Fig 8 does not describe CW direction. It mentions the start-up behavior and calibration process and how it affects the output signal triggering for forward direction.
As the datasheet of TLE5028C has mentioned, Counter Clock Wise (CCW) rotational direction is emitted as forward pulse at the signal output.
Clock Wise (CW) rotational direction is emitted as backward pulse at the signal output.
So TLE5028C-XAA-D28 CW 90us, CCW 45us,
For the inverse types, "CCW rotational direction is emitted as backward pulse at the signal output. CW rotational direction is emitted as forward pulse at the signal output".
TLE5028C-XAI-D28 CW 45us, CCW 90us

------------------------------------------------------------------------------------------------------
Figure 8 Start-up behaviour and output signal triggering (direction forward). Drawing valid for TLE5028C-XAA-D28 and TLE5028C-XBA-D28
==>
In the title description (direction forward), does it use CW to describe "Start-up behaviour and output signal triggering"?

Hi @Yashraj_P ,
Good day~
So TLE5028C is defined opposite to TLE5027C?
Because I once looked at the following description and thought the output types were the same.
The TLE5028C adds an improved immunity towards ESD and EMC to adress the problems, caused by harsh high power environments like from hybrid systems. TLE5027C and TLE5028C are available in our well-established, module-style package with integrated capacitors.
