TPS7A54: Discharge resistance

Part Number: TPS7A54
Other Parts Discussed in Thread: TPS7A52

Hi, teams.

I wan to calculate the discharge time.

According to DS, there is resistor for active discharge in TPA7A54 and it is desribed as "several hundred ohms".

Can you provide specific values?

Also, How much variation should we consider for it?

Hi Hayakawa,

The active pulldown resistance is 198.2Ohms, and a +-20% variation should be used for this resistor value.

Hi, John

Thank you for your reply.

Is ti the same for TPS7A52?

Hi Hayakawa,

Yes, the TPS7A52 should have the same architecture for the pulldown resistance.
