Part Number: PCA9306
Hello, I am using the PCA9306TDCURQ1 on my design and need a little help determining the current consumption. I have connected Vref1 to 1.8V and Vref2 to 3.3V. If anyone can give me some help I would greatly appreciate it.
Thanks,
Joe
Hi Joe,
A simple estimation of the idle supply current is (Vref2 - Vref1) / 200k-Ohm. The actual power is supplied by the source connected to Vref2.
More detailed current measurements have to do with the pull-up network connected to the device and the device's internal Ron. More information on these calculations can be found from this post:
Let me know if you have any more questions.
Regards,
Eric
