TPS4811-Q1: Can the over-temperature threshold be brought down from 150 degrees

Michelle Mathew

Part Number: TPS4811-Q1

Tool/software:

Hi,

The remote temperature sensing document for TPS4811 mentions a fixed threshold of 150 degrees at which over-temperature fault will be triggered. Is there any design change, where in I can bring down the temperature threshold to a lower value like 100 degrees.

Regards,

Hi,

Will adding a resistor in series with bjt help bring down the threshold value. If so, how can we select the value of the resistor.

Regards,

Michelle

Hi Michelle,

The temperature sensing is not configurable for this device. It is intended as a protection feature for the device itself which is intended to operate below 150C.

Thanks,

Sarah
