Hi Zoey,
If the customer doesn't want open load detection and is still having issues with it, they can connect a pulldown resistor to VOUT to ensure the voltage stays below the open load threshold. Does this work?
Thanks,
Patrick
Part Number: TPS27S100 Hi team,
Could you please answer questions below?
Question 1
Question regarding startup when TPS27S100 is ENABLEd
I believe that if you set a current limit value externally, it will clamp to that current value at startup. In other…
Hi Elizabeth,
sorry for the delay and thank you very much for the check.
Unfortunately, adding more diodes to the ground path does not change voltages in the circuit. Moreover such complicated ground network could be hard to accept, both for FMEA calculations…

In my design I use TPS27S100BPWPR to support 6A@100ms pulse .
Can I use two TPS27S100BPWPR in parallel to support 11A@100ms pulse ?
There is similar smart load switch with…
Part Number: TPS27S100 Other Parts Discussed in Thread: TPS22997 , Hi,
I am currently implementing Power Switch driver TPS27S100APWPR and will be using logic to toggle the output from 28V to open; a logic low at EN input I am expecting an open at the output…
Part Number: TPS27S100 Hello,
In the datasheet it says: "External adjustable current limit – An external resistor is used to set the current-limit threshold. Use Equation 2 below to calculate the RILIM. VILIM(th) is the internal band-gap voltage."…
Hello,
Although we don't have a dedicated application design for that specific use-case, we do have application examples in the datasheet and the user's guide of the evaluation module for the TPS27S100 device: https://www.ti.com/tool/TPS27S100A…
Part Number: TPS27S100 Hello,
Is there any way to shorten the fault recovery time for this device? Right now we're seeing the FAULT pin stay LOW for about 60ms after a startup inrush current event.
Thanks,

Part Number: TPS27S100 Hi Team
Let me ask about the thermal shut down.
In the datasheet, Absolute maximum temperature is Tj=150℃. But thermal shut down temperature is 175℃. Thermal shut down temerature is over the AMR value (150℃).
Then , how can I understand…
