ARRGH!  I used the HIP4080 in a servo amplifier about 20 years ago.  I kept 
blowing them up.  After talking to an applications engineer, I found out 
that that "80 Volt" part had never successfully been run above 50 V.  Well, 
I was running them at 59 V, but they kept popping.  I eventually redesigned 
the whole thing with the IR2113S, and never popped anything else.  But, it 
did require a lot of extra circuitry to replace all the stuff the HIP4080 
did in the PWM modulator functions.

I've been using the TA8050 successfully for a while.
As I recall it it's good for 1.5amp with 7pin connection (1 not used).
It's rated as a motor driver max 30v with all the protections (O/V , O/C 
etc).
