TPS82084: PG and EN pull-up resistor value for 3.3V pull-up voltage

JH Shin

Part Number: TPS82084

Hello,

My customer would like to know the recommended pull-up resisstor values for PG and EN of the TPS82084.

When using 3.3V pull-up voltage, what is the recommended pull-up resistor value for PG and EN? How should the customer determine this value?

Thanks in advance.

Hi Shin,

As I understand from the datasheet, typically a 499k pull-up resistor can be used for the PG pin.

To calculate EN pin pull-up resistor (R_EN_pull-up) please use the below formula:

V_EN(min) = VIN_min (400k/R_EN_pull-up + 400k)

Please let me know if you need further help!

Regards,

Febin
