Part Number: ISO7742
Hi team,
I'm estimating the power dissipation , my customer spec is 3.3V 1Mbps,
I saw the power dissipation for side-2 is 100mW,
however,
the power according to this graph is only about 9.9mW which is way more smaller than the 100mW we just saw,
may I know which should I refer to?
Hello Fred,
Thank you for your question. Figure 9 is shows supply current of the ISO7742 typical application within recommended operating conditions (e.g., typical supply voltages, room temperature, and full data rate range). As you have shown, this can be used to estimate typical power consumption for the device. Please refer to Figure 9 and 10 when estimating ISO7742's supply current for typical power consumption calculations.
Table 7.5 refers to the device's power dissipation under a worst-case test condition (max supply voltage, max temperature, and max data rate).
I hope this helps.
Best,
Andrew
