General Description 

The epc70x family is a general purpose high-side power switch for 24V interfaces. A low-side switch is also available, please refer to the separate data sheet of epc700/702. The device is capable to drive a load of 50mA at 30VDC.

 If a higher driving current is necessary or if the output voltage shall be higher than 30VDC, these chips can be used to drive an external power transistor. In this mode of operation, the external transistor is fully protected against over-current by the epc chip. 

If the current through the external load exceeds a specified threshold during a longer time period than a predefined time, the output is turned off to protect the output switch. The switch is turned on again after a predefined off-time, thus enabling the load again in a self-healing mechanism. 

The over-current information is indicated on the STATUS pin. epc701 and epc703 are easy to use and reduce the need of external components to the minimum, thus saving pcb space and money
