APPLICATION INFORMATION  
shutdown circuitry  
COMP also can be employed to introduce external control of the SG2524. Any circuit that can sink 200 µA can  
pull the compensation terminal to ground and, thus, disable the SG2524.  
In addition to constant-current limiting, CURR LIM+ and CURR LIMalso 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.  
current limiting  
A current-limiting sense amplifier is provided in the SG2524. The current-limiting sense amplifier exhibits a  
threshold of 200 mV ±25 mV and must be applied in the ground line since the voltage range of the inputs is limited  
to 1 V to 1 V. Caution should be taken to ensure the 1-V limit is not exceeded by either input, otherwise,  
damage to the device may result.  
Foldback current limiting can be provided with the network shown in Figure 7. The current-limit schematic is  
shown in Figure 8.
