Avago Releases Extended Temperature 2.5Amp Gate Drive Optocouplers for Industrial Apps

Avago Technologies announced the release of an extended temperature 2.5 Amp gate drive optocouplers for use in a range of industrial applications.

?

Avago's ACPL-312U, which is a member of the R2Coupler family, incorporates an alloy lead frame to offer heat dissipation, which allows it to operate over an extended industrial temperature range from -40 to 125 degrees C. These extended temperature optocouplers from Avago target designers of isolated IGBT/power MOSFET gate drives, industrial inverters, AC and brushless DC motor drives, and uninterruptable power supplies. Avago is a supplier of analog interface components for communications, industrial and consumer applications.

Avago's ACPL-312U provides reinforced insulation and reliability that delivers safe signal isolation which is critical in automotive and high temperature industrial applications. The low-power ACPL-312U optocoupler series has been designed with under voltage lock-out protection (UVLO), high common mode rejection (CMR) performance and high speed response to improve efficiency. Moreover, it is developed with a double wire bonding process to provide added redundancy and reduce wire breakage during high temperature operation. Additionally, the low 5mA maximum supply current of this series of optocouplers allows bootstrap operation and reduces IC power consumption. As a result, costly isolated power supplies or DC-to-DC converters can be reduced when these gate drive optocouplers are used, the company noted.

?

Avago's series of 2.5A gate drive optocouplers contain an AIGaAs LED, which is optically coupled to an integrated circuit with a power output stage. The high operating voltage range of the output stage provides the drive voltages required by gate controlled devices. Moreover, the voltage and current supplied by these optocouplers are ideal for directly driving IGBTs with ratings up to 1200 V/100 Amps. For IGBTs with higher ratings, this series of optocouplers can be used to drive a discrete power stage which drives the IGBT gate.

?

The ACPL-312U series of optocouplers come in a standard DIP-8 package with a creepage of 7.4 mm and clearance of 7.1 mm. These DIP-8 packages are compliant to most industrial safety standards such as IEC/EN/DIN EN 60747-5-5, UL 1577 and CSA.

?

Avago's ACPL-312U extended temperature 2.5A gate drive optocouplers are available now through Avago's direct sales channel and worldwide distribution partners.
