HCPL-3020/ 0302 0.2 A Output Current Gate Drive Optocoupler
from Agilent Technologies
The HCPL-3020 in DIP-8 and HCPL-0302 in SO-8 package complement Agilent’s existing family of gate drive optocouplers. The new 0.2 A devices consist of GaAsP LEDs optically coupled to an integrated circuit with a power output stage. The current rating, combined with the high common mode rejection (CMR), fast switching and latchup performance uniquely qualify these optocouplers for low-power inverter gate drive applications. The high operating voltage ranges of the HCPL-3020 and HCPL0302 output stages provide the drive voltages required by MOS-gated devices like IGBTs or MOSFETs. The voltage and current provided by these optocouplers make it suitable for driving IGBTs with rating up to 1200 V/ 20 A. For IGBTs with higher ratings, the HCPL-0314/3140 (0.4 A), HCPL-3150 (0.5 A) or HCPL-3120 (2 A) can be used. The HCPL-3020 and HCPL0302 are among the cheapest solutions available for driving MOS-gated devices in a safe, efcient, reliable and cost-effective way. Besides ease of implementation, the HCPL-3020 and HCPL0302 also excel in power consumption. The low supply current of 3 mA allows
bootstrap techniques, thus eliminating additional isolated power supplies for gate drive circuitry. Using discrete power IGBTs or MOSFETs together with gate drive optoisolators instead of integrated modules allows the designer to con……
