Somebody knows why evaluation boards use a DA9053 PMIC instead of freescale MC13892 PMIC? Are there any problem with the MC13892 for this design?
Dialog don't have publish information about the DA9053 in the web. Also I don't find technical information, manuals, detail distributors or prices for this chip.
i'm not a "company" so i cannot request the DA9053 datasheet. I need to investigate on why the PMIC isn't powering the processor's RTC in my IMX53QSBs. No response from Freescale so far, i just wanted to see if there's any register in the DA9053 that controls that voltage and must be programmed with some value from uboot.
Hi, just thought I'd let you all know that there is a PMIC from Wolfson that supports the i.MX53. There are some designs in production using the WM8325 and the i.MX53.
Take a look at Linear Technologies LTC3589-1. The i.MX53 System Development User's Guide has an example of how to use this PMIC with the i.MX53.
See section 5.3 of that document. You can download it here:
Perhaps the MC34708FS is the ideal and final candidate to sustitute the MC13892 as PMIC on MX53 designs ?.
The only downside is that it is still under development and Freescale doesn't let us download a preliminary datasheet.That's a pity.
