Part Number: INA139
Dear colleague,
Our customer is planning to do a design in the brick power module for preventing current backflow. The previous solution is a diode, but as the power rate increases, a diode has more power dissipation. So we want to use…
Hi Shawn,
I would recommend taking a look at INA181 ( INA181 data sheet, product information and support | TI.com ) for your design.
If cost is the priority INA181 is our cost-optimized solution for bi-directional current sensing.
You can take a look at…
Part Number: INA139 Other Parts Discussed in Thread: INA170 Hi there
I'm following up on a test related to the INA139 and simulations in TI-TINA.
The current that I want to take to sample is from -2.5 A to +2.5 A, and the frequency is range from 100K…
Part Number: INA139-Q1 Other Parts Discussed in Thread: INA139 Hi team,
Our customer asked a question about INA139Q1.
Could you support to answer these questions?
1. I want to know the internal circuit between PIN 8 and PIN6 in INA139-Q1 for DFMEA analysis…
Part Number: INA139 Other Parts Discussed in Thread: INA190 , INA191 , INA186 Hi,
I have referred to the datasheet and found that there is a VOUTMAX which indirectly imposes a limitation on current measurement.
My application would be to have this on different…
Part Number: INA139 Other Parts Discussed in Thread: INA271 , INA282 , INA283 Hello Sir,
Good Evening,
This is Eazhil Having some doubt with Current sensor INA139 SOT23-5. Previously i'm using INA271 SOIC Package for High side current sensor for my circuit…
Hey Robert,
What you have described is correct. The output compliance voltage of the INA139 is always limited by the shunt voltage (Vdiff), input common-mode (Vcm = Vin+) and power-supply (V+). If you need more compliance voltage headroom you could power…
Part Number: INA139 Other Parts Discussed in Thread: INA282 , , TPS22959 Hello Peter,
we have discussed in a previous conversation about INA139 to sense 10A current and INA282 to sense 10mA to 50mA, as shown in the picture below.
I want have the possibility…
Part Number: INA139 Other Parts Discussed in Thread: INA190 , INA169 , INA181 , INA180 What are the best ways of minimizing the effects the input offset voltage. I have an INA139 being fed into an ADC and the Vo error makes any low current measurements meaningless…
