  • TPS2661: TPS2661x Same Supply Operation

    Resolved
    Part Number: TPS2661 I want to know if the TPS2661x family of devices could be used in the following scenario: I have multiple 4-20mA instruments powered by a single power supply. I want to protect this power supply from potential shorts between…

  • TPS2661: TPS26611: Continuous ±30 V analog-input miswiring protection with supplies off or partially powered

    Part Number: TPS2661 Hi TI team, We are evaluating a ground-referenced 4–20 mA input using two TPS26611DDFR devices. Each field terminal connects through 47 ohms to IN. The IP-side OUT feeds a 120-ohm burden to ground; the IM-side OUT is grounded, with…

  • TPS2661: Problem with TPS26610 and 4-20mA sensor previously powered

    Part Number: TPS2661 Hello, I use the TPS26610 to protect the two wire 4-20mA analogic input in my design. The device, read periodically the input and power the TPS to take the measure. It can power too the sensor at same time or the sensor can be powered…

  • TPS2661: TPS2661x Simulation

    TI Thinks Resolved
    Part Number: TPS2661 Tool/software: I want to implement protection for a 4-20 mA analog input from voltage supply (from a voltage source) up to 30 V. It is better if the sensor connection is floating (so that the GND of my circuit does not match one of…

  • TPS2661: Reset after Latch-Off

    Resolved
    Part Number: TPS2661 Tool/software: How does the TPS26610 reset after a latch-off when input < -Vs? If the input rises above Vs does it automatically recover? Or does it need to be power cycled?
