ISO1410: Supply current

Part Number: ISO1410
Other Parts Discussed in Thread: ISO1450,

Hi,

Is the supply current of ISO1410 lower than ISO1450 in the case of the same data rate( i.e. 500kbps)?

Best Regards,

Kuramochi

    Hi Kuramochi-san:

    Thanks for posting your question on E2E.

    ISO1410 Icc2 supply current is similar to ISO1450 Icc2 supply current at 500 kbps when Vcc2 is 3.3 V. ISO1410 Icc2 current consumption is slightly higher than ISO1450 Icc2 current when Vcc2 is 5 V. This is due to the ISO1410 driver slew rate control implementation. Please see below for the comparison of the datasheet supply current typical curves over data rate. Also note that the Icc1 is the same for both devices at 500 kbps.

    You may refer to the ISO1410 datasheet Typical Curves section for more supply current comparisons.

    Regards,
