  • INA239: INA239 isolation?

    TI Thinks Resolved
    Part Number: INA239 Other Parts Discussed in Thread: TIDA-01608 Hi! I was using this IC to sense current, voltage, and power. From the datasheet it looks like it does not have isolation built in to electrically isolate the Sensing pin side from the SPI…

  • INA239: Low-Side Power sensing application

    Part Number: INA239 Hi! I need help with using a low side sensing application with the INA239. So far I have it working with a high-side sensing application but it does not work for the low side sensing application. Also I would like to add that it only…

  • INA239: Inaccurate shunt values after power-reset

    TI Thinks Resolved
    Part Number: INA239 Other Parts Discussed in Thread: TI-SCB Hello, I am noticing an oddity with the IN239 where after a power-reset the shunt value readings are incorrect or shorted out. This happens for either single-shot or continuous mode for 280us…

  • INA239: EVM/SCB Connect Fail

    Resolved
    Part Number: INA239 The system routed "INA239" to the Amplifiers forum. Since it's actually a power (current/voltage) monitoring sensor, apologies if that's not correct forum. The TI items are: Sensor Control Board SENS077 Evaluation…

  • RE: INA239: INA239

    Resolved
    Hello Zhao, Here are my responses to your questions. (1) The datasheet does not associate the conversion time with a specific number of samples from the ADC. This is partly because it is not a set number of samples, but samples over a set amount of time…

    Part Number: INA239 Other Parts Discussed in Thread: INA229 , , SYSCONFIG W e have connected the INA229_239EVM to our system. and we can not get any response from SO. please check the trimming plots and let us know if you see any issue If you have any comment…

  • INA239: Read VBUS at 0x0000 some rare times

    TI Thinks Resolved
    Part Number: INA239 Other Parts Discussed in Thread: SYSCONFIG Hi, I use INA239 to get VBUS and current. I used Sysconfig. Some rare case, I read 0x0000 on VBUS register. The ADC is configured as continuous. I read the register asynchronously. Should…

  • INA239: Best way to protect it

    TI Thinks Resolved
    Part Number: INA239 Hello all, my goal is to design a very reliable PCB to test a product (motor). The INA239 measures the bus voltage (48V) and current (Imax 20A) going inside the motor. We are using an industrial power supply to simulate the battery…
