ISO7720: Current consumption in function of temperature

Etienne Vanzieleghem

Part Number: ISO7720

The ISO7720 does not specify the evolution of the current consumption (ICC1, ICC2) in function of temperature. Could you provide that information?

Hi Etienne,

https://e2e.ti.com/support/isolation/f/1013/p/816562/3021669

Please refer to this post concerning a similar request. Unfortunately we don't characterize this data for our isolators but the the typical current value is representative of the current consumed at 25C and max current value should be representative of current consumed at 125C.

Respectfully,

Lucas

Hi Etienne,

Welcome to E2E! As Lucas mentioned above, a trend line is not shown graphically on the ISO7720 datasheet, but the typical and maximum current consumption values are specified across operating conditions. If you'd like some data plots, I can capture them using a couple samples in the lab. What are the power supply voltages and inputs you would like to evaluate?

Thank you for your time,
Manuel Chavez

Hi Etienne,

Below are plots of ISO7720 typical Iccx measurements across temperature for Vcc1 = Vcc2 = 3.3V and various inputs:

Hopefully this is helpful! Please let us know if there is more information or insight we can provide.

Thank you for posting to E2E,
Manuel Chavez
