  • TPS272C45: Failures during output short circuit

    Part Number: TPS272C45 Hi Team, This is a continuation of the other thread below. https://e2e.ti.com/support/power-management-group/power-management/f/power-management-forum/1173652/tps272c45-failures-during-output-short-circuit I just received…

  • TPS272C45: Using Vdd as an external power supply to other devices

    TI Thinks Resolved
    Part Number: TPS272C45 Hello, Can the VDD pin be used to power external components like an op amp?

  • TPS272C45: Failures during output short circuit

    Part Number: TPS272C45 Hello, we are having serious problems with TPS272C45ARHFR. In our application, we use software to disable the switch after overcurrent situation has continued for 20 milliseconds, and then retry after 10 seconds (again keeping…

  • TPS272C45: Setting Current Limit below Minimum Specified in Datasheet

    TI Thinks Resolved
    Part Number: TPS272C45 Other Parts Discussed in Thread: TPS2H000-Q1 Hi, I see on the datasheet that the max Rclim value is 28.2k, which results in a current limit of ~727mA. Rlim = Kcl / Icl --> 28.2k = 20.5 / Icl --> Icl = 727mA For my application…

  • TPS272C45: Reverse Current Protection causing Voltage Offset b/w System Ground + Protected Ground

    Resolved
    Part Number: TPS272C45 Hello, In our recent design we followed the instructions for the recommended Reverse Current Protection on the TPS272. However, we do measure a 0.25V difference between DGND and HSD_24VHC_GND1 (the protected ground). My questions…

  • TPS272C45: max allowed reverse current

    Resolved
    Part Number: TPS272C45 Hello Team, The TPS272C45D is used in a setting where VOUT > VS in some cases, which leads to an inverse current through the MOSFET body diode. There is no specification in the data sheet regarding the maximum reverse current…

  • TPS272C45: No UVLO at Vdd=5V

    TI Thinks Resolved
    Part Number: TPS272C45 Hello Team, Connections: VS=24V, Vdd=5V from external independent power supply; load at OUT1 is about 10mA When disconnecting the 24V the VS pin should be 0V, correct? But is stays at 4.2V and the UVLO does not trigger. Page…

  • TPS272C45: Is there errata for this part?

    Resolved
    Part Number: TPS272C45 Hello, We noticed a different behavior of FLT signal at TI evaluation board and the latest assembled boards. For the same conditions: Diagnostic disabled, EN0 = 1, EN1 = 0 Latch = 1 On evaluation we set overcurrent limit and…
