TPS65381A-Q1: TPS65381A-Q1 DIAG_OUT resistance in AMUX mode

masahiko shimizu

Part Number: TPS65381A-Q1

Hi,

My customer is using TPA65381A-Q1.
This post is to just forward you information.

DIAG_OUT resistance in AMUX mode is max 15kohm.
It is hard to use for big resistance and < 200nA in or out current of this pin.
Next generation product should be more small output impedance.

Best regards,
Shimizu

Hi Shimizu-san,

Thank you for the feedback regarding next generation considerations, this is not the first time we have received this feedback. As part of the continual improvement process, TI has altered the next generation functional safety devices AMUX to address the constraints found in this first generation SEooC device.

Best Regards,

Scott
