TPS274C65: Maximal Pulse Energy

Part Number: TPS274C65

Hello TI team,

I am interested in the maximum pulsed energy the (clamped) high side switch can handle when demagnetizing a inductive load.

Chapter of the TPS274C65 datasheet references the electrical charracteristics ("The maximum single pulse and repetitive pulse energy is defined in Electrical Characteristics."), linking to table 7.5. I am however unable to find any energy in there.

Thanks, and best regards

  • Hi Jerome, 

    The maximum energy and the load inductance can withstand for one pulse inductive dissipation at 125C is shown below:

    If the application parameters exceed this device limit, please use a protection device like a freewheeling diode to dissipate the energy stored in the inductor.

    Best Regards,
