ABSTRACT:
A circuit for limiting power dissipation through telephone subscriber line power supply interface devices, by using a pair of final stages to which an external component effective to dissipate power is connected. By use of separate discrete reference circuits, the presence of excessive common mode current is detected; and when this occurs, current to the driver stages is controlled at a lower magnitude.
