24V/50mA General-Purpose Output-Driver
General Description
Features
The epc70x family is a general purpose low-side power switch for 
24V interfaces. A high-side switch is also available, please refer to 
the separate data sheet of epc701/703. The device is very easy to 
use and 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.
Low-side power switch
Driving capability without external transistor 50 mA/30VDC
Programmable short-circuit detection delay-time and recovery time
Static (epc700) or flashing (epc702) indication of the over-current
status
Self-healing output mode
Available in CSP6 package with very small footprint and standard
QFN16 package
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.

epc700 and epc702 are easy to use and reduce the need of ex-
ternal components to the minimum, thus saving pcb space and
money.
