Walter,
I think the HIP4040 is a Harris Semiconductor part. You may also want
to look at International Rectifier's IR2104 or STM's L6384. The HIP
devices had problems with device failure. Depending on the reverse
recovery characteristics of the MOSFET's intrinsic drain-to-source
diode (hyper-abrupt recovery), voltage spikes can exceed -5 volts due
to the device's source lead inductance. This negative voltage caused
CMOS latch-up and failure of the HIP part. I don't see these problems
with the IR or SMT part.
