The HCPL-3120 contains a GaAsP LED while the HCPL-J312 and the HCNW3120 contain an AlGaAs LED. The LED is optically coupled to an integrated circuit with a power output stage. These optocouplers are ideally suited for driving power IGBTs and MOSFETs used in motor control inverter applications. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. The voltage and current supplied by these optocouplers make them ideally suited for directly driving IGBTs with ratings up to 1200 V/100 A. For IGBTs with higher ratings, the HCPL-3120
series can be used to drive a discrete power stage which drives the IGBT gate. The HCNW3120 has the highest insulation voltage of VIORM=1414Vpeak in the IEC/EN/DIN EN 60747-5-5. The HCPL-J312 has an insulation voltage of VIORM = 1230Vpeak and the VIORM = 630Vpeak is also available with the HCPL-3120 (Option 060).

The HCPL-7800(A) isolation amplifier family was designed for current sensing in electronic motor drives. In a typical implementation, motor currents flow through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7800(A). A differential output voltage is created on the other side of the HCPL-7800(A) optical isolation barrier. This differential output voltage is proportional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended application circuit. Since commonmode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the HCPL-7800(A) was designed to ignore very high common-mode transient slew rates (of at least 10 kV/μs).

The Broadcom® ACPL-C87B/C87A/C870 voltage sensors are optical isolation amplifiers designed specifically for voltage sensing. Its 2V input range and high 1-GΩ input impedance, makes it well suited for isolated voltage sensing requirements in electronic power converters applications, including motor drives and renewable energy systems. In a typical voltage sensing implementation, a resistive voltage divider is used to scale the DC-link voltage to suit the input
range of the voltage sensor. A differential output voltage that is proportional to the input voltage is created on the other side of the optical isolation barrier.

The HCPL-7840 isolation amplifi er family was designed for current sensing in electronic motor drives. In a typical implementation, motor currents fl ow through an external resistor and the resulting analog voltage drop is sensed by the HCPL-7840. A diff erential output voltage is created on the other side of the HCPL-7840 optical isolation barrier.
This diff erential output voltage is proportional to the motor current and can be converted to a single-ended signal by using an op-amp as shown in the recommended application circuit. Since common-mode voltage swings of several hundred volts in tens of nanoseconds are common in modern switching inverter motor drives, the HCPL-7840 was designed to ignore very high commonmode transient slew rates (of at least 10 kV/μs).

The HCPL-22XX, HCPL-02XX, and HCNW22XX are optically-coupled logic gates. The HCPL-22XX, and HCPL-02XX contain a GaAsP LED while the HCNW22XX contains an AlGaAs LED. The detectors have totem pole output stages and optical receiver input stages with built-in Schmitt triggers to provide logic-compatible waveforms, eliminat ing the need for additional waveshaping.
