9.4.2 Shutdown Circuitry

COMP also can be employed to introduce external control of the SGx524. Any circuit that can sink 200 μA can pull the compensation terminal to ground and, thus, disable the SGx524.

In addition to constant-current limiting, CURR LIM+ and CURR LIM– also can be used in transformer-coupled circuits to sense primary current and shorten an output pulse should transformer saturation occur. CURR LIM– also can be grounded to convert CURR LIM+ into an additional shutdown terminal.
