Other Parts Discussed in Thread: TCA9509, TCA39306
Dear team
there are some questions when my customer use PCA9306. in case we are discussing same application, using 1.8V to 3.3V open drain as an example.
I have learn from LSF training video, and understand why we use pull-up res 200K in EN and vref2 pin. but still confused by these questions like below
- PCA9306 must have pull-up resistor in EN pin when open drain application, why other sockets like pull up resistor for TCA9509 EN pin is not must.
-
TCA39306 is the P2P solution with Pca9306, which has better performance, wider voltage range, and higher speed rate. there are no limit for EN pull-up resistor in TCA39306, why? could you help to explain in schematic view?
