Optocoupler operates over industrial temperatures
An Avago Technologies product story
Edited by the Electronicstalk editorial team May 19, 2009
Avago Technologies has announced extended temperature 2.5A gate drive optocouplers for use in a wide range of industrial applications.
Avago's ACPL-312U, which is a member of the R2Coupler range, incorporates an alloy lead frame to offer superior heat dissipation, which allows it to operate over an extended industrial temperature range from -40 to 125C.
These extended temperature optocouplers from Avago target designers of isolated IGBT/power Mosfet gate drives, industrial inverters, AC and brushless DC motor drives, plus uninterruptable power supplies.
The ACPL-312U provides reinforced insulation and reliability that delivers safe signal isolation 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, the cost of isolated power supplies or DC-DC converters can be reduced.
The 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.
The voltage and current supplied by these optocouplers are suitable for directly driving IGBTs with ratings up to 1,200V/100A.
For IGBTs with higher ratings, this series of optocouplers can be used to drive a discrete power stage that drives the IGBT gate.
The ACPL-312U series of optocouplers come in a standard DIP-8 package with a creepage of 7.4mm and clearance of 7.1mm.
These DIP-8 packages are compliant to most industrial safety standards such as IEC/EN/DIN EN 60747-5-5, UL 1577 and CSA.
