General Description
The OL2068 is an industrial power line driver and contains four identical short circuit proof differential line drivers up to 30 Volts driver supply with a joint enable function. An internal 5 V power supply is used as reference and supply voltage for the circuitry and is able to supply max. 5mA for external 5V components like a sensor or a constant current source for a LED. The very small outline TSSOP package gives excellent thermal power dissipation, thus the usage in space limited applications is easy.

NOTE: Stresses above those listed under "Absolute Maximum Ratings" may cause permanent damage to the device. This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability (eq. hot carrier degradation).

Look at over-temperature protection Table 3 For surface mounting plastic packages. Valid for normal function. To disable automatic thermal shutdown, this pin should be set to 7,5 12 Volt. Limited by power dissipation.
Driving capability at elevated temperatures will be limited by total package power dissipation. Special packages up to 125°C can be supplied OPTOLAB Microsystems GmbH * Haarbergstr. 61 * 99097 Erfurt / Germany * Tel. +49-361-422906-0 * Fax +49-361-422906-50 * www.optolab.com 2/9

Either the low or high side switch is active at a time. Values will not be part of the production test but guaranteed by design. 8 Output MON external driving current up to 4 mA possible but using this limits the thermal power budget ! 9 Measured without external load on VCCI pin, all outputs open. 10 For decoupling VCCI please connect this output with a 100nf capacitor to GND 11 Depends on supply voltage VCCD, VCCI could be not higher than VCC - 0.3 V. 12 This is measured per input with all other inputs held at VCCI or GND. 13 Limited by power dissipation, high ICCI current with growing VCCD voltage generates heat, thus the driving limit can be reached earlier 14 Value will not be part of the production test but guaranteed by design.
