TFP401 - Power Down Current (IPD)

Hello,

Could you please let me know the typical value of IPD?
Are there any method to decrease the IPD(max) from 10mA? Our customer would like to reduce the power consumption at the Power Down mode.

Best Regards,

Hello,
There is no method to decrease the IPD, the device is at its lowest power consumption when PD is asserted.

Hello Elias,

Thank you for the reply.
How about typical value of IPD?

IPD can't be lowered neither, your best option is to connect terminal SCDT to PDO# so you can power downs the output drivers any time there is not a valid input.

Hi Elias,

In the datasheet, there is the maximum value only on the IPD.
I would like to know the typical value of IPD.
Is the typical value almost 10mA?

Hello,
We provide maximum levels based on the maximum input voltages and temperature of operation, the typical value will vary depending on your conditions, but yes, you could consider a number close to the IPD max as the typical value.
