Recommended Voltage for DA1469x

Hi,

I was looking for some feedback on determining the supply voltage for the components in the DA1469x series. I am aware that there are maximum and minimum thresholds, but I am unsure how to determine the maximum and minimum cutoffs for my specific application. To provide some additional context on a higher level, the MCU of my intended application will use a Li-ion battery, which will power a display, an IR proximity sensor, and the memory components of the MCU. My thought is that I need to finalize my hardware peripherals first, but I was wondering if there are any other approaches in determining the proper power requirements.

If you can help me, I would truly appreciate your response.

Thank you.

Hi sgutala,

Hi sgutala,

Thanks for your question online. I not completely sure if I understood your question correctly but please refer to DA1469x Datasheet and see Table 4: Absolute Maximum Ratings and Table 5: Recommended Operating Conditions.

Since it is a custom board, I would also recommend checking the AN-B-066: Hardware Design Guidelines document.

Thanks, PM_Dialog

Thank you for the response. I

Thank you for the response. I had a quick follow up question. Do you happen to know the maximum power rating for the DA1469x? I have looked through the datasheet but could not find any explicit mention of it.

Hi sgutala,

Hi sgutala,

Do you mean Table 4: Absolute Maximum Ratings from the datasheet? The absolute maximum voltage on the VBAT is 6V.

Thanks, PM_Dialog
