  • TPS22946: Max current limit at Vin = 5V with CL open

    Part Number: TPS22946 Hi Team, We use TPS22946 as the load switch for our OHRM power supply. In our schematic design, the CL pin is float. Hence, the current limit should be 30mA. In my projects’ main board ATE, we conducted a test using a 75ohm load…

  • TPS22946: Discharge function on VOUT when the switch is turned off

    Resolved
    Part Number: TPS22946 Does the TPS22946 have a built-in discharge circuit that bleeds the output when the load switch is disabled (ON goes LOW)? If not, can you suggest a different ultralow power load switch that has a discharge function or can you suggest…

  • TPS22946: Can't ON when supply volage increase from 2.3V to 4.6V

    TI Thinks Resolved
    Part Number: TPS22946 Hi team, Customer has 2pcs TPS22946 that has problem in below situation. In customer design, when Vin=2.3V, ON=0V. when Vin=4.6V, ON=2.3V. Normal device can output when Vin increase. But there are 2pcs can't output when Vin increase…

  • TPS22946: Ultra Librarian Footprint vs. Datasheet Footprint

    Resolved
    Part Number: TPS22946 Hello, I have a question about the footprint for the TPS22946 load switch presented in the datasheet versus the one available in the Ultra Librarian site. In the datasheet of the TPS22946, the recommended pad diameter is 0…

  • TPS22946: TPS22946 Problem

    Part Number: TPS22946 Hi Team, I have serious problem with this device. Load on VDD_SBP about 12mA and capacitance 500nF and after resistor 100Ω additional 3.3uF Input +3.3V can be switched off and on by electronic switch. When I switch +3.3V…

  • TPS22946: OC flags on startup: False OC indications, already discussed in an earlier thread

    Part Number: TPS22946 Hello, I've designed-in the TPS22946 as switch with current limit into my sensor board, which turns on 25 sensors. At startup ( power on ) I often see the TPS22946 flag an overcurrent indication, mostly even although no sensor…

  • TPS22946: OC flag on startup on some circuits but not others

    Part Number: TPS22946 Hello, I have a number of circuits using the TPS22946, and I see random startup failures on some but normal operation on others. Tried many troubleshooting steps to see if I can get a circuit that fails to start to function properly…

  • TPS22946: Serious problem: Random start failures, no output power.

    Resolved
    Part Number: TPS22946 Serious problem here with TPS22946YZPR. Randomly the chip does not start. Happens on many device we tested. There appears to be a relation with the time the input power was off. We could reproduce this several times with…

  • TPS22946: Failed to switch on after EN signal applied

    Resolved
    Part Number: TPS22946 Hello, We're using a large number of TPS22946 (280psc) to control power supply for level shifters in our signal multiplexer design. And we observe that some of the switches are not turning on once EN signal is applied. It happens…

  • TPS22946: Is there any similar component, with similar size, that switches at higher current ?

    TI Thinks Resolved
    Part Number: TPS22946 Hi all, Do we have a similar component, with similar size, that switches at higher current? The motor for the application is not yet defined, therefore the needed current might be higher. Thanks and best, Miriam
