  PCA9306: EN pin to VREF1 instead of VREF2

  Answer Suggested

  Part Number: PCA9306 If VREF1 is 3.3V and VREF2 is 5V and both VREF1 and VREF2 comes up at the same time. Is there any concern for tying EN pin to VREF1 @ 3.3V thru a pullup?

  PCA9306: Can i drive the EN pin with an open drain AND gate?

  TI Thinks Resolved

  Part Number: PCA9306 Hi team, in the datasheet, it only references a design where VREF2 (ex. 3.3V) drives EN pin. is it ok to instead drive the EN pin with an open drain AND gate also powered at 3.3V? are there any design concerns to consider...
