The SSRs will draw 3mA each. My idea was to sink each 3 mA current through a different unique GPI pin when I command it low, as a low-side switch . so one GPI pin is for only one SSR. Can I do this with the PCA9703? It seems that I can't, and the device cannot tolerate such current. Which is it?</P> Mon, 20 Sep 2021 20:07:55 GMT https://community.nxp.com/t5/Other-NXP-Products/PCA9703-current-limit/m-p/1342919#M12111 gmarq922 2021-09-20T20:07:55Z https://community.nxp.com/t5/Other-NXP-Products/PCA9703-current-limit/m-p/1343819#M12125 <P>Each input pin of PCA9703 can sink 100uA.</P> Wed, 22 Sep 2021 08:07:01 GMT https://community.nxp.com/t5/Other-NXP-Products/PCA9703-current-limit/m-p/1343819#M12125 guoweisun 2021-09-22T08:07:01Z
