TPS26600-02EVM: Resistance between UVLO, OVP pins to RTN

Part Number: TPS26600-02EVM

Hello

I was trying to change the OVP threshold on the TPS26600 EMV and replaced the R8 and R3 with calculated values, but I noticed that the OVP was still 32.4V and not 31.6V as I wanted it to be. When I measured the resistance using a DMM between OVP and RTN pins, I noticed that it was only 19.2ohms which means that the device is still taking default value of 33V.

Similarly for the UVLO, the resistance was quite small as well. Can you please tell me what should be the resistance between UVLO <--> RTN and OVP <--> RTN pins?

Regards

AJ
