TMS320F280049C-Q1: Maximum input current

Julia Li

Part Number: TMS320F280049C-Q1

Tool/software:

Hi Champs,

Could you help to check the maximum input current of below pin? Is there a risk if the input current reaches 45A?

Thanks!

Best regards,

Julia

Is this a typo?

Pasting datasheet specifications below.

Hi Ben,

Yes, this is a misunderstanding described by customer. The 45A is converted into a voltage signal and input to the ADC pin after processing.

So the maximum input current is 20mA. If the input exceeds 20mA, what will happen to the F280049? Will it reset or will it damage the chip?

Thanks!

Best regards,

Julia

The chip will be damaged.

Also please see in the notes that the maximum continuous current is 2mA.
