Other Parts Discussed in Thread: TPL7407L

Hi all

Would you mind if we ask TPL7407L.
We apologize that we keep pestering you again,,,

Could you let us know the difference between Maximum Output Current Figure.4 and Maximum Collector Current on Figure.8 on the datasheet P6?
Are these the same meaning?

Kind regards,

Hello Matsumoto-san,

These are two different ways of looking at the maximum current.
Figure 4 shows the maximum current as a function of the temperature, assuming a 100% duty cycle.
Figure 8 shows the maximum current as a function of the duty cycle, assuming a 70C temperature.

Does this make sense?

Best,
Michael

Thank you for your reply always.

We apologize that we would like to hear what the difference between the word 「Max Collector Current」 and the word 「Max Output Current」.

These meanings are the same, right?

Kind regards

Matsumoto-san,

I understand more clearly now. Yes, Max Collector Current and Max Output Current mean the same thing in this case.

Let me know if you have any further questions.

Best,
Michael
