Hello,
You appear to be describing emergency shutdown followed by restart.
The TPS650864 / TPS650861 family will initiate an emergency shutdown if any of the enabled voltage rails does not reach the target voltage within 10 ms.
I would recommend…
Hi PAN-M,
For a ZU2CG design with max current of 2.1 A, it mostly depends whether a 5V rail is desirable or not. If not, the TPS65086401 is likely more preferable (less rails used so fewer external components). For these low currents, TIDA-01480 is…
Viktorija,
Correct, VCCINT_VCU was separated out by Xilinx after the initial release of the ZU+ family.
The TIDA-01480 design added it as a note in the block diagram, but the Ultra96 board from Avnet is fitted with the ZU3EG so there is no need…
Naveen, Unfortunately, these devices are not able to be programmed outside the TI factory. For high volumes, custom OTPs can be generated (you would need to reach out to your TI representative in this case). The TPS65218D0 and TPS650861 both offer a customer…
Hi Nicky,
[2020 Edit: The TPS650861 is the user programmable version of TPS650860 which can be programmed for a wide variety of cases and is an excellent option for FPGA attach with a wide variety of current]
We don't have a PMIC reference design…
Shreenidhi,
I see you already looked at a question on the Zynq Ultrascale+ and asked this as a follow-up question.
The TPS650864 can be used in most of the large, power-hungry Xilinx applications. We have recently been working on power proposals for…
Other Parts Discussed in Thread: TPS650861 , TPS650864 , CSD87350Q5D , CSD87588N , CSD87381P Hello Ti,
I have a few questions regarding the PMIC – P/N:TPS650861
The PVIN3,4,5 input pins (Converters) can be 3.3V – 5.0V.I want to use 3.3V to PVIN3…
Hi Markus,
We do not have an equivalent 4 controller device but what about using the TPS650861? This is our only released software programmable non-volatile memory multi-rail PMIC, though we are expanding our selection. It would be able to power the…
Vikas,
It looks like they are using very different settings than the defaults for the TPS65086401 device. I have a feeling that the settings are not being set correctly, especially because settings like which CTL pins enable which regulators are not…
Hi Gregory,
1) The current from BUCK1, BUCK2, and BUCK6 is limited by the FET selection and ILIM pin resistor selection. The BUCK controllers can work with FETs up to 30A. Once you have a target current in mind, you can use the equations in Section…
