OL2068 Industrial 30 Volt 4-Channel Differential Power Line Driver - Short Circuit Proof Applications • Industrial encoder interfacing • Industrial sensor interfacing • Proximity switches • Industrial controllers • Light barriers Features · Ultra small package TSSOP 20 · Max. voltage range from 4,5 V – 36 V · Short circuit proof tri-state outputs drive up to 120mA sink / source · Operating frequency up to 4 MHz · Integrated voltage reg. with 5V output · Dynamic peak current up to 1,5 Amp. · High impedance CMOS / TTL compatible buffered inputs with hysteresis · Outputs RS422A compatible Line voltage in Ultra small package TSSOP 20 Voltage regulator 5V , 5mA out 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 an LED. The very small outline TSSOP package gives excellent thermal power dissipation, thus the usage in space limited applications is easy.
