TPS25810: Power Sequence

yana

Part Number: TPS25810

hi,

Is there a power sequence to supply the TPS25810 itself?
Is there no sequence for supplying voltage to the IN1 pin, IN2 pin, AUX pin, etc.?
In other words, even if 5V is applied to the IN2 pin, is it OK if no voltage is applied to the AUX pin?

Thanks,

Hi Yana,

Let me check on the power sequence for device power with my team and get back to you early this week.

Best,

Alex

Hi Yana,

We do not have a specific requirement for power sequencing between IN1, IN2, and AUX. The important thing is that AUX is what actually powers on the TPS25810, so the device will be disabled until AUX supply is present. It is ok to have IN1 and IN2 powered before AUX becomes available, or vice versa.

Best,

Alex

Hi Alex

I understood that the power sequence is in no particular order.

Thanks,
