TPS274C65: Maximal Pulse Energy

Jerome Kaufmann

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 9.3.5.3 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
Jerome

    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,
