IXYS driver IC controls high-current power MOSFETs, IGBTs

The IXDD415 is a high-speed, HF CMOS MOSFET/IGBT driver IC that has two driver channels, each capable of 15A peak into a capacitive load. This makes the chip suitable for controlling high-current, HF power MOSFETs and IGBTs.

Offering high-speed, high-frequency drive capabilities, the device also feature very low rise and fall times of 2ns (matched), and switching frequencies up to 45MHz. It operates over a wide supply voltage range from 8V to 30V. It can be driven by either TTL or CMOS input signals.

Each driver is fully immune to latch-up within 0A to 15A output. A very low propagation delay time and a very low output impedance make it very useful for driving HF, medium-current MOSFETs or medium-current fast IGBTs. It is housed in standard 28-pin SOIC package.

This driver also features proprietary tri-state outputs. With "enable" pin on high, the output voltage swings in response to the enable signal. Once the pin goes low, the output goes into a high impedance state. This allows an auxiliary circuit to slowly turn-off the MOSFET or IGBT to protect it from voltage transients.

Applications are in RF and power electronics industries. Other applications include: Class D and E switching RF amplifiers, multi-megahertz dc/dc converters and SMPS; pulse transformer drivers; pulse generators; pulsed laser diode drivers; and acoustic transducer drivers.
