Hi team,

In the TMAG5231, the Ton (Power-on time) seems to vary widely as shown below. What causes this value to change?

Best regards,

Hello Kyohei,

Thanks for considering to use Texas Instruments, I am forwarding your response to our design and validation team to see if I can get some sort of explanation. I will try to give you an update tomorrow.

Hello Kyohei,

Unfortunately I cannot reveal too much on why that is other than the power blocks are slow at power-up and there is some initial uncertainty for the circuitry that sets up the sample time due to a certain circuit element not being fully set up prior to the first edge of the device's internal clock.
