  • RE: TPS2596: Overvoltage clamp

    Hi Eric, So this is a OVCSEL pin. You cannot program the OVC for values other than provided in the datasheet i.e. 3.8, 5.7 and 13.7V. The pin allows some margins so using 402k or 399k resistors won't cause any issue. As you asked what will happen for…

  • TPS2596: Disable and multiple devices

    TI Thinks Resolved
    Part Number: TPS2596 Hello, I plan to use multiple TPS259620DDA devices in my design. These are latching parts, and my understanding is that to unlatch I need to cycle the Enable pin. So, I have 2 questions. 1. What is the minimum time to drive the Enable…

  • TPS2596: Voltage Clamp

    Resolved
    Part Number: TPS2596 Hello, I've 15V as main supply and a 12V lead acid battery to backup it. I need a voltage limiter circuit to drive a 9~12 siren, and protect from short circuit. TPS259621 clamp output voltage at 13.8V, using 2x diode I think…

  • TPS2596: EMC/EMI Filter

    TI Thinks Resolved
    Part Number: TPS2596 Hello, I intent to use TPS259630 to a power management equipment, responsible to supply some sensors and drivers using cables from 5 to 15 meters. I add reverse voltage protection, and a bead on input. I'd like to know if it is…

  • TPS2596: Thermal characteristics of TPS2596

    Resolved
    Part Number: TPS2596 Other Parts Discussed in Thread: TPS2597 Hi, If my understanding of this part is correct, the shutdown of the device in short circuit failure relies on the Junction temperature exceeding the thermal shutdown temperature? This means it…

  • RE: TPS2596: Help with Post-mortem of TPS259630 (why did it die?)

    Resolved
    I think the 2-3V is with 10's of amps of current but still I understand that even at more reasonable currents it is not down to 0.3V which is the max negative voltage supported by the TPS2596. Perhaps those Schottky diodes will help as you recommend.…

  • TPS2596: Fault signal is not asserted for ILIM pin short to GND condition

    TI Thinks Resolved
    Part Number: TPS2596 Hi, We have TPS259631 in our design. We are trying to create and test the fault condition 'ILM Pin Short to GND' as shown in Table 3 of TPS2596 data sheet. But we are not seeing the FLT# signal getting asserted when shorting…

  • TPS2596: Paralleling of eFuses, RIlim calculation

    TI Thinks Resolved
    Part Number: TPS2596 Other Parts Discussed in Thread: TPS25924 , Hi My application uses 4x TPS259631 eFuses. For one of the fuses, a typical load is a very high overall capacitance, (8000uF). This causes large inrush currents on startup tripping the fuse…
