Part Number: ISO7762-Q1

Hi team,

Our customer asked us about a question to ISO776x-Q1.

Is there timing requirement to wait ISO776x-Q1 between power up VCC and operation? Does customer need to wait some time after power up VCC?

Regards,

Nishimura

    Hi Nishimura,

    Like every other device ISO776x will also take some finite time for it to power-up and operate normally. The startup time for ISO776x is typically expected to be about 100µs while it can go upto 180µs for under worst-case conditions. It is best to operate the device only after 180µs after VCCx > 2.25V. Thanks.
