Part Number: INA303 Hi,
in our application INA303 is putting the ALARM pin in an active state, immediately after power up (this is likely due to the slow power-up as mentioned in the datasheet).
Now, we also use the Latched mode, which holds the ALARM…
Part Number: INA303-Q1 Hi TI Team,
We have considered INA303A1 current sense amplifier for our design.
We are using this device for bi-directional current sensing.
So we have given an external 2.25 V REF reference using a simple voltage directly to REF…
Part Number: INA303-Q1 The integrated current sense amp+dual comparator IC features one of the comparators' output delayed (comparator 2: Latch 2 and Alert 2).
Section 7.3.3 of the datasheet has the delay calculation formula in the attached snipet…
Part Number: INA303-Q1 Hello team,
I am Oliver Kim who supports automotive customers in TI Korea.
Could you share the INA303-Q1 sample and RTM schedule? Can I get the samples by the end of April?

Thanks…
Hi Sarmad,
250mA is a huge current to go into INA303. As part of your probe, you may want to verify and confirm. You could insert a pair of 1~10Ohm resistors on the input pins. If the current indeed is somehow going through these resistors, you should…
Part Number: INA303
I am using INA303A2 for sensing current at high side with both thresholds set to monitor overlimit i.e. ALERT1 threshold at about 158.31mA and ALERT2 threshold at about 183.64mA. The circuit works fine in TINA but on board it in an…
Part Number: INA303 Hi
I'm referring SBOA171B.
In this note, low-side sensing with INA303 is introduced.
Regarding to detection for motor current, I concern impact of noise.
Should not we need consider the input filter for INA303?
Could you please…
Part Number: INA303 Other Parts Discussed in Thread: OPA313 , Hi,
I am looking into the circuit design of INA303. This part is very helpful for overcurrent protection with window comparator integration.
In INA303EVM design, the reference voltage divider…
Part Number: INA303 Hi,
I am currently working on a design and I am using the INA303A2. I an using the evaluation module INA303EVM (the one with 50V/V gain). Here is the schematic I am using, with some notes.
I have a 1mOhm sense resistor to measure…
