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?

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: INA381 Other Parts Discussed in Thread: INA303 , INA302 , INA300 1m ohm shunt is used to measure current. 2 INA381 ICs are used to measure bidirectional current in battery for charge (6A) and discharge (110A). When ever Surge is applied across…
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…
Hi,
Thank you for choosing INA381:
The 1M resistor could be too big, and comparator most likely will have trouble functioning properly (depending on settings) due to the extra-large hysteresis introduced. The comparator input is high impedance. While…
Part Number: INA301 Other Parts Discussed in Thread: INA302 , INA303 , INA234 , INA181
Hello, I have a question about the hysteresis of the INA301. Do to design specifications, I would like to use the A3 reference with a Vlimit of 50mV. Nevertheless, the…
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…
