IXYS Corp. (Santa Clara, CA) announced the introduction of the IXDD408 and IXDD414, new CMOS high-speed MOSFET/IGBT driver ICs. With respective current drive capability of 8A and 14A, the ICs are suitable for controlling high-current, power MOSFETs and IGBTs and medium-current MOSFET and IGBT modules.
The new driver ICs feature a tri-state output. With the ENABLE pin high, the output voltage swings in response to the input signal. Once the ENABLE pin goes low, then 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 LdI/dt-generated voltage transients.
The devices also feature 25ns rise and fall times, which are matched. They operate over a supply voltage of 4.5V to 25V and can be driven by either TTL or CMOS input signals. Both the IXDD408 and the IXDD414 are immune to latch-up within their output current range. In addition, the ICs have a low propagation delay time and a low output impedance.
The IXDD408 and IXDD414 drivers are available in standard 8-pin PDIP prototyping or in 5-lead, TO-263 surface-mount packaging for high-volume manufacturing. Possible applications include the motor controls, UPS systems, dc/dc converters, SMPS, pulse transform drivers, switching amplifiers, pulse generators, pin diode drivers, line drivers and local on/off switches.
Pricing in 1,000-piece quantities for the 8-pin PDIP prototyping is $1.99 each for the IXDD408 and $3.64 each for the IXDD414. In TO-263 packaging, the devices are $2.23 each for the IXDD408 and $3.89 each for the IXDD414, in the same quantities.
