Other Parts Discussed in Thread: INA199 Hi TI,
we have prepared 5 prototypes and found an issue about the battery charging and apart from it D2D and dimming works well.
Initially when both the battery(12V) and solar(20V) inputs connected, MPPT loop…
Hello Hirotaka,
Of course we can assist you. The INA240 should have no problem with driving the 470pF capacitor and it does not have trouble with stability when driving a 1nF. You can read about stability analysis for our devices here: e2e.ti.com/…
Grady,
Unfortunately, we currently do not have plans to release any of our wireless charging devices in the automotive space. However, we do see our INA199-Q1 and INA210-Q1 devices used here for protection. Can you share what the application here is…
HI Yaita-san,
That is not a typo, that is correct. Version A and Version B have different ESD structures. This difference on ESD structure caused the ESD rating of the B version to be lower than A. We are working on releasing a spin of version B to…
Thanks, Javier and Rabab.
Does the opamp in the figure represent an ideal one, with no error currents? In that case I can see where error currents from the Bias block would pass almost exclusively through Rshunt and have little effect on the output…
Hey Rahul,
I am unsure of what you are trying to accomplish. I will assume you are still trying to measure 150mA to 200mA and this requires a very simple circuit when using a current sense amplifier. Previously you had said VS=3.3V and shunt resistor…
Hi Helen,
I don't think the low efficiency is caused by the layout directly. When the current is small, the efficiency is also low. 5V 1A, 5V 2A and 5V 3A have no big difference. And the themal for 5V 1A is OK.
The EVM has better thermal data because…
Dear Simmons,
Could you please help answer the two question below?
1. If the load current range is 0.1mA--100mA, and I choose the INA226 as current sense IC, 800mohm as the shunt resistor(81mV/100mA). Does the solution make sense?
2. There is…
