  • INA219: INA219 Back powering the application circuit/ MCU while powered down

    Part Number: INA219 Other Parts Discussed in Thread: TLV709 We have a product with the INA219 being solely used for bus voltage monitoring. The IN+ and IN- terminals are shorted together on the board since we don't want to use a shunt resistor or current…

  • INA219: INA219 return Shunt Voltage reading much higher than actual

    TI Thinks Resolved
    Part Number: INA219 Other Parts Discussed in Thread: INA220 Hi Experts, We are using INA219 to perform Voltage and Current Measurment The voltage reading is OK (~12V) – Reg 02 The current (shunt voltage – Reg 01) reading gives results which is higher…

  • INA219: what causes INA219 to explode in circuit

    Resolved
    Part Number: INA219 Tool/software: Hi, We have implemented multiple INA219 shunts to monitor up to 10A current on multiple circuits. The circuit uses a fuse with known resistance (5 mOhms) as the shunt resistor, everything else is standard reference…
