Q: TPS3809I50 RESET Resistor requirement. by 1621419

Is the requirement now that you have to add a resistor to "reset not" output?

If so, what value resistor should he use?  What value should I assign (R171) the Reset not output or is this 100 K is okay? Thanks.

Per the datasheet, the minimum requirement is Vpullup/50uA.  This requirement keeps the IC from entering test mode.  If they don't pull /RESET higher than VDD during startup, they don't need the resistor

 More  form the customer Do I still need to add resistance to the device as per the reference in other documentation? He only added R171 as per the data sheet suggested for the TPS3809.
