TPS63060: About PG voltage

Kaji@PAN

Part Number: TPS63060

Tool/software:

Hello,
I am an FAE at a distributor that handles TI products.
I received the following question from a customer.

I would like to ask about the "PG output low voltage" listed on the datasheet.
Under TEST CONDITIONS it says Ipgl=10uA.
(Question 1)
Is this 10uA a value determined by the pull-up resistor?
(Question 2)
If the answer to question 1 is "yes", what is the maximum voltage of "PG output low voltage" for example Ipgl=300uA?
It says that MAX=0.4V for 10uA, so I would like to know what the MAX value is for 300uA.

Best regards,

Hi kaji,

In our test, 10uA is a constant current source. But for coustomer side, yes you can think this current is decided by pull-up resistor.

Acording the variation of Vpg with 10uA current, we can know the range of resistance for internal PG FET when Vout is 5V is from 4K to 40K. Then if a 300uA current applied, the max value of PG will be 12V, which is impossible for mostly application.
