Product Summary

The OL7272LF 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. The applications of the OL7272LF include Industrial encoder interfacing, Industrial sensor interfacing, Proximity switches, Industrial controllers, Light barriers.
