Hello all,

Thank you for your support always. Can you tell me the time from POR to reading/writing data is available on OPT3001(-Q1)?

Best regards,

Hi Ryo,

Just to confirm, do you mean from General-Call Reset Command POR or device power up?

Hello Alex,

Thanks for your reply. I would like both data if there is difference between POR by command and by supply voltage over threshold (device power up).

Best regards,
RYO

Hi Ryo,

Power-On-Reset (POR) which happens during power up (supply ramp). The POR circuit detects the supply ramp-up and generates a reset. For this reset, the supply has to become stable to start any i2c command.

General-Call Reset is i2c based. For this reset, no delay should be required to start the next command since supplies are stable. Next i2c command can immediately start following the General-Call reset command.

Best,

Alex
