In the DA9062-EVAL1:
- What is the full P/N of the DA9062 IC?
- What will be the default OTP version ? Can you share the Buck/LDO voltages + sequence?
- In case we are using different power sequence, what options we have to update the PMIC EVM for our needs (assuming the IC already arrived programmed with OTP)?
- Is it possible to used the EVM while the the IC is unprogrammed (no OTP) by using PC mode with INI file?
Let me answer your questions 1.) The part number changes slightly depending if the OTP of the part is programmed or not. DA9062-XXAM1 is for parts on a tray AMC are parts in T&R. We have some standard variants like: - DA9062-0AAM1 for Qualcom Atlas 7 (On tray) - DA9062-11AM1 Avnet MiniZed boardRead more

1.) The part number changes slightly depending if the OTP of the part is programmed or not.
DA9062-XXAM1 is for parts on a tray AMC are parts in T&R.
We have some standard variants like:
– DA9062-0AAM1 for Qualcom Atlas 7 (On tray)
– DA9062-11AM1 Avnet MiniZed board
– DA9062-62AM1 i.MX6S Autoboot
– DA9062-A0AM1 In Circuit Programming Variant (this is an empty unprogrammed part)
Please note that the in case of an automotive option there is an additional -A at the end of the code. These parts will need to be programmed at factory to fulfill the AEC-Q100 etc requirements.
2.) On the EV Kit there is a preprogram that has following outputs.Buck1 1.38V, Buck 2 1.5V, Buck3 3.3V and buck 4 1.8V, LDO1 3.3V, LDO2 1.8V,LDO3 3.0V and LDO4 2.8V.
sequencing is slot1 LDO1, slot2 Buck1, slot3 Buck2, slot4 Buck3, slot5 Buck4, slot7 LDO 2 and 3, slot8 LDO4.Step time is set to 1,024ms.
3.) There is a switch on the mother board that defines a mode we call Power Commander (PC mode). This mode prevents normal or programmed OTP register transfer to softregister, instead it writes the soft registers from the selected INI-file You can create yourself with the GUI and edit as you wish and save it. This will not be programmed to the OTP but it can be used for testing etc.
4.) it is possible but one should be very careful and rememmber to turn on the power commander mode on, the switch. but you can do exactly pretty much the same with programmed part.
