24V/50mA General-Purpose Output-Driver

Features

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.



High-side power switch

Driving capability without external transistor 50 mA/30VDC

Programmable short-circuit detection delay-time and recovery time

Static (epc701) or flashing (epc703) 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.

Applications



PLC

Sensors

Controllers

epc701 and epc703 are easy to use and reduce the need of ex-

ternal components to the minimum, thus saving pcb space and

money.
