Anti-oversaturation function deletion circuit schematic with desaturation protection

A connection diagram is given to delete the anti-oversaturation network fork and retain the desaturation protection function
. In the figure , the diode VD is connected in series with two diodes VD, and VD,.
The current produced by the UAA4002 is determined by the resistor R, and the collector-emitter voltage is still monitored, although
the UAA4002 pin ve. The voltage difference between the terminal and the collector of the driven transistor is equal to the voltage threshold of
the three diodes , but since the driven transistor works in an oversaturated state , this will not cause the problem that the driven transistor cannot be protected after desaturation+
