Description
The HCPL-3100/3101 consists of an LED* optically coupled to an integrated circuit with a power output stage. These optocouplers are suited for driving power MOSFETs and IGBTs used in motor control inverter applications. The high operating voltage range of the output stage provides the voltage drives required by gate controlled devices. The voltage and current supplied by these optocouplers allow for direct interfacing to the power device without the need for an intermediate amplifier stage.

The HCPL-3100 switches a 3000 pF load in 2 µs and the HCPL3101, using a higher speed LED, switches a 3000 pF load in 0.5 µs. With a CMR rating of 5 kV/µs typical these optocouplers readily reject transients found in inverter applications.
The LED controls the state of the output stage. Transistor Q2 in the output stage is on with the LED off, allowing the gate 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 and voltage to drive the gate of the power device.
