Part Number: TPS22976

Hi team,

Up to how many a of current can be used the output pull-down resistor?
Customer assumes 1.8-V voltage.

Best regards,

Hi Goto-san,

This isn't specified or tested, but the current through the QOD pin would be 1.8V / 230Ohm = ~8mA. I think that should be fine for steady state. Anything larger I would be very careful on - why does the customer want to force current through the QOD resistor?

Thanks,

Patrick

Hi Patrick,

Thank you for your reply.

Customer uses like this system for unique evaluation.
Specifically,
1.8V +/- 10%, 9mA(max), 20min flow
Is this condition safe?

Best regards,
Goto
