Part Number: TPS65084
Other Parts Discussed in Thread: TPS59641, TPS51716, TPS650861, TPS650860EVM-116, TPS65086, TPS650864, BOOSTXL-TPS650861

Hi Sir 

May I know TI have PMIC for Baytrail-M or Baytrial-D?

As I know TI have Braytrial-T CR SND9039 PMIC solution 

Thanks

    Hello,

    We do not have a PMIC for Baytrail-M or Baytrail-D. I have looped in our core controller team as they have supported Baytrail with TPS59641 in the past though if you are interested in a discrete approach.

    Hi Kevin 

    If Vcore use TPS59641 others power rail use PMIC ,do you have any solution could be used ? Need to support DDR VDDQ and VTT

    Hi Kaileh,

    For DDR (VDDQ+VTT), we do have TPS51716, which can supply both VDDQ and VTT. It's a discrete solution though.

    Regards,

    Hi Kaileh,

    We do not have a pre-defined solution for BayTrail other than CR. Looking at Bayley Bay design as an example, with a 2S-4S battery or 12V input, TPS650861 might be the closest fit from the PMIC team and it is user programmable to support various power up / down sequences.

    It could support high current 5V / 3.3V / VDDQ + VTT + 3 additional voltages (V1P8, V1P0A, V1P05S seem like decent candidates) + 3 load switches, depending on what power states you are trying to support.

    Details of the internal structure for programming as available in the Programming Guide: www.ti.com/.../swcu188

    Hi Kevin 

    May I know TPS650861 have EVM ? I saw TI have TPS650860 EVM ,but I can't make sure what's different between 860 and 861 

    Besides TPS650861 only have TPS65086100 part number ,seems like this is for NXP PMIC

    Hello,

    TPS650860A0RSKx, the only orderable under TPS65086 product folder, is a pre-programmed version of TPS650861 that is intended for demonstration purposes. It has a power-up sequence and a power-down sequence example. This is what is populated on the TPS650860EVM-116. The default settings for this spin are located here: www.ti.com/.../swcu186

    TPS65086100RSKx, the only orderable under TPS650861 product folder, is a blank version of TPS65086 which can be programmed using the OTP Generator Excel file + I2C. It does not do anything by default. In the TPS650861 product folder, there are example programming files in the Design & development section under Design tools & simulation tab - this includes all of the TPS650864 OTPs (another family of pre-programmed TPS650861 devices targeting Xilinx) as well as the LS1043 example. 

    The TPS650861 does not have a solder down EVM, it has the BOOSTXL-TPS650861 board which is a socketed board for prototyping. From there, the units programmed in the BoosterPack can be soldered to a TPS650860EVM-116 after making the necessary modifications for proper operation.
