AB class amplifier question

[berni80]

Hi,

I've to design a single supply AB class BJT amplifier,
with protection to short-circuit to ground and to the positive supply..

I need something similar to the OPA564:

I need the shunt-down and the over-current flag.
Do you have any idea about how to implement them on a AB class output stage?

Thanks!
