Part Number: TPS6521825 Other Parts Discussed in Thread: TIDA-050038 , TPS6521815 Hello TI Forum, I have a circuit that utilizes the TIDA-050038 reference design. This design uses a TPS6521825 and LP873347 PMIC to provide power to an i.MX 8M mini processor…
Part Number: TPS6521825 Hello,
I am considering using the LP873347 and TPS6521825 to power an i.MX 8M Mini processor. A previous PMIC I was evaluating for this purpose has the weird quirk where, when the PMIC was commanded to turn off, it would cause…
Part Number: TPS6521825 Hello TI Forums,
On TPS6521825, can anyone confirm if the nPFO signal is controlled by PWR_EN? If PWR_EN is low, does that force nPFO to go low as well? Or is PFI the only pin that controls the state of nPFO?
Thanks!
Part Number: TPS6521825 Hello,
I'm interested in using the TPS6521825 in a circuit I am making, and I have a question about the power-up and power-down sequence this chip goes through. I understand that if PWR_EN goes high, the chip will start the…
Part Number: TPS6521825 Hello,
I'm interested in using the TPS6521825 in a circuit I am designing, and I had a question about the voltage supply pins for this IC. The voltage source I am using to power this chip is normally <5.5V, but occasionally…
Part Number: TPS6521825 Other Parts Discussed in Thread: TPS65218D0 Hi,
Which one is the TPS6521825 default ouput voltage?
a) DCDC3=3.3V, DCDC4=1.8V (for i.mx8mm) b) DCDC3=1.2V, DCDC4=3.3V (datasheet table 5-2)
I am worried that the contents of the table…
Part Number: TPS6521825
Hello TI Forum,
Can anyone tell me what is the maximum input voltage for digital input pins on the TPS6521825? The datasheet doesn't say. Specifically, I want to know the max input voltage for PFI, PB, PWR_EN, SDA, SCL, GPIO1 …
Part Number: TPS6521825 Other Parts Discussed in Thread: LP8733 , TPS6521815 Hi team,
TPS6521825 is for NXP i.MX 8M Mini. Would it be possible to use for NXP i.MX 8M Nano?
The design compatibility guide from Mini to Nano states few changes in power supplies…
Part Number: TPS6521825 Other Parts Discussed in Thread: TIDA-050038 , LP8733 , TPS6521815 , TPS650861 Hi, I wonder if one can combine e.g. DCDC1 and DCDC2 of TPS6521825 to one rail to get higher output current.
Thank you

Hi Daniel,
Thanks for the reply. I did some more digging into this issue and discovered the answer to my initial question: a short circuit is not a short circuit when it is caused by insufficient voltage on the input to the LDO. As for why there is insufficient…
