The HCPL-3000 consists of a Silicon-doped Ga As LED optically coupled to an integrated circuit with a power output stage. This optocoupler is suited for driving power bipolar transistors and power Darlington devices used in motor control inverter applications. The high peak and steady state current capabilities of the output stage allow for direct interfacing to the power device without the need for an inter me-diate amplifier stage. With a CMR rating of 1.5 kV/us this optocoup-ler readily rejects transients found in inverter applications. The LED controls the state of the output stage. Transistor Q2 in the output stage is on with the Le Doff, allowing the base of the power device to be held low. Turning on the LED turns off transistor Q2 and switches on transistor Q1 in the output stage which provides current to drive the base of a power bipolar device. Functional Diagram CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation which may be induced by ESD. THE USE OF A 0.1uF BYPASS CAPACITOR CONNECTED BETWEEN PINS 8 AND 7 IS RECOMMENDED. ALSO, CURRENT LIMITING RESISTORS ARE RECOMMENDED (SEE FIGURE 1, NOTE 2, AND NOTE 7).
