2.5A IGBT Gate-Drive Optocoupler Features Wide Temperature Range

With an operating temperature range from -40°C to 125°C, the ACPL-312T optocoupler from Avago Technologies is suited to driving the power IGBTs and MOSFETs used in automotive motor-control inverter and DC/DC converter applications.

The ACPL-312T contains an AlGaAs LED 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 makes them ideally suited for directly driving IGBTs with ratings up to 1200V and 100A. For IGBTs with higher ratings, the ACPL-312T series can be used to drive a discrete power stage, which then drives the IGBT gate.

 

FEATURES 2.5A maximum peak output current 25kV/µs minimum Common Mode Rejection (CMR) at 1500V VCM 5mA maximum supply current Under Voltage Lock-Out (UVLO) protection with hysteresis Operating VCC range: 15V to 30V 500ns maximum switching speed

APPLICATIONS Automotive motors DC/DC converters Isolated IGBT/MOSFET gate drive AC and brushless DC motor drives Industrial inverter systems Switch-mode power supplies
