IXYS and Clare Introduce New Optically Coupled Driver for Power MOSFETs IGBTs and Thyristors

IXYS Corporation (NASDAQ:IXYS) and Clare, Inc., a wholly owned subsidiary of IXYS, announced the introduction of the IX3120 2.5A “optocoupled” Gate Drive. The IX3120 driver combines Clare’s expertise with the OptoMOS product line with the newly introduced ‘600 Series’ of high current gate drivers. The input signal is provided by a light emitting diode (LED) which is optically coupled to an integrated circuit (IC) that contains a high performance high-speed CMOS power output stage. This combination provides, isolated driver capabilities without the use of isolation transformers, enabling smaller footprint and lower cost solutions. “Optically isolated gate drivers are ideal for power switching and control applications where designers have bridge configurations of Power MOSFET, IGBTs or Thyristors, or any combination of them. This IX3120 solves the need to provide input to output isolation with the ease of driving the high-side devices in half bridge, full bridge configurations and in multilevel inverter power stages,” commented Mark Heisig, President of Clare-IXYS, a product family that combines the IXYS power semiconductor DNA, with Clare’s IC OptoMOS driver technology. The IX3120 output is capable of providing 2.5A of peak drive current. The IX3120 has a wide supply voltage range of 15V to 30V and features high common mode rejection (minimum 25kV/us at Vcm = 1500V) which makes for excellent noise elimination. Under voltage lockout is provided for additional protection. The IX3120 is well suited for applications that use switching power MOSFETs or IGBTs, such as DC/DC converters, SMPS, industrial and Solar inverters, motor drives, and uninterruptible power supplies

IXYS-IC. Design and manufacture of high voltage devices, analog-digital hybrid devices, optical isolation devices and communication ICs. The long history of IXYS-IC in analog/mixed-signal and high-voltage designs has made IXYS-IC a pioneer in highly integrated semiconductor solutions. These solutions replace magnetic materials in wired interface applications and greatly improve performance. Experience in high voltage and mixed signal applications has also brought IXYS-IC to other high-growth areas, including industrial, consumer and new flat panel display markets. IXYS-IC. is the original CP Clare Corporation, founded in 1937 by Carl P. Clare, which provides high voltage switching technology for the communications market. For more than 60 years, Clare has turned from an electromagnetic device manufacturer to the leader of the last inch of silicon solutions in the last mile of communications, with its expertise in high voltage applications. In July 2002, Clare, Inc. was acquired by IXYS Corporation and is now a wholly-owned subsidiary of IXYS, the IXYS-IC business unit.
