Conclusion

It is important to know how your device will act thermally so that efforts can be made to select the right device for your application. High-side switch devices offer many load protection features, among them, thermal shutdown. Although, thermal shutdown can affect whether or not a load can be driven using a high side switch device, this protection feature can be better understood and accounted for using the available PSpice models located on TI.com.
