TPS2660: MODE pin resistor

Part Number: TPS2660

Hi,

Following is an extract of the datasheet.

My customer needs "Current limiting with latch", however they are using E24 series resistors, so 402kΩ is not listed.

Is 390kohm allowed for setting to this mode?

Hi Kuramochi,

390k can be used to obtain the same behaviour.

Venkata-san,

Thank you for your information.

I have an additional question
What is voltage range of MODE pin when we set current limiting with latch?

Best Regards,

Hi Kuramochi-San,

Resistor range for latch-off is 200k to 600k. I would suggest to select the resistor in the range from 300k to 500k.

Nandam-san,

Could you show me the voltage range of MODE pin when we set current limiting with latch?

Best Regards,
Kuramochi
