Functional Diagram Features • 1000 V/ µs Minimum Common Mode Rejection (CMR) at VCM = 50 V for HCPL-2602 and 3.5 kV/ µs Minimum CMR at VCM = 300 V for HCPL-2612 • Line Termination Included – No Extra Circuitry Required • Accepts a Broad Range of Drive Conditions • LED Protection Minimizes LED Efficiency Degradation • High Speed: 10 MBd (Limited by Transmission Line in Many Applications) • Guaranteed AC and DC Performance over Temperature: 0 °C to 70°C • External Base Lead Allows “LED Peaking” and LED Current Adjustment • Safety Approval UL Recognized – 2500 V rms for 1 Minute CSA Approved • MIL-STD-1772 Version Available (HCPL-1930/1) A 0.1 µF bypass capacitor must be connected between pins 5 and 8. Applications • Isolated Line Receiver • Computer-Peripheral Interface • Microprocessor System Interface • Digital Isolation for A/D, D/A Conversion • Current Sensing • Instrument Input/Output Isolation • Ground Loop Elimination • Pulse Transformer Replacement • Power Transistor Isolation in Motor Drives Description The HCPL-2602/12 are optically coupled line receivers that combine a GaAsP light emitting diode, an input current regulator and an integrated high gain photo detector. The input regulator serves as a line termination for line receiver applications. It clamps the line voltage and regulates the LED current so line reflections do not interfere with circuit performance. The regulator allows a typical LED current of 8.5 mA before it starts to shunt excess current.
