TPS274160: TPS274160

Part Number: TPS274160

Wanted to know whether the TPS1H100 and TPS274160 IC’s meets the DC-14 Electrical technical specification.

  • Hi Kaushik,

    Our part didn't go through DC-14 qualification processes. The standard passed will be noted in the datasheet like below. Please let me know if you have additional questions.



  • We wanted to know whether the TPS1H100 and TPS274160 IC’s meets the DC-14 Electrical technical specification. as per

    The Standard IEC 60947-5-1

  • It is fine if the Parts TPS1H100 and TPS274160 is not tested for the DC-14 , we just wanted to know if switch can handle the specification theoretically as per standard IEC 60947-5-1. Also wanted to know what will happen if the load tries to draw 20A from the TPS1H100 and TPS274160 Device , The Current limit circuit and protection should not get spoiled.

  • Hi Kuashik,

    Please let me know if I understand the standard from the screenshot correctly: the device needs to enable into 10 times of nominal current for at least 25 ms? For TPS1H100, the internal current limit can kick in at 7A. If the load is resistive and nominal current is less than 0.7A, then our part should be able to pass assuming it doesn't cause thermal shutdown - it will be depending on the load resistance (the lower the worse the thermal). 

    If the load is inductive, then an external clamp between VS to VOUTor VOUT to GND will be needed to dissipate inductive energy during turn-off.

    Same thing goes for TPS274160 consider the internal current limit is 6.5A.

    Please let me know if you have further questions or comments.
