Ixys Corp.'s dual 2A MOSFET/IGBT driver (IXD402) and single 9A device (IXD409) are optimized to drive large-volume, midpower-range insulated-gate bipolar transistors (IGBT) and MOSFETs with either an inverting or a noninverting configuration.

The IXDF402 can be operated in a differential mode. Package options include 8- and 16-pin SOICs, five-pin TO-220 and TO-263, and 8-pin DIP casings.

Target applications include UPS and switch-mode power supplies, dc/dc converters, controllers for inverters, motor controls, Class D amplifiers, pulse transformer drivers, pulse generators, and line drivers.

Fast switching speed and high-current drive capabilities are enhanced by low, matched rise-and-fall times on the order of 14ns, according to the company. A patent-pending circuit is said to all but eliminate cross-conduction in the output stage.

The drivers operate over a supply voltage range from 4.5V to 25V. The 25V rating suits them for driving discrete IGBTs requiring 15V gate bias and makes them immune to power supply transient voltages.

Low propagation delay time and low output impedance suit the devices for driving fast power MOSFETs and ultrafast IGBTs. Both can be driven by either TTL or CMOS input signals.

In quantities of 1,000, prices range from $1.60 to $2.04. Samples are available from stock. Production quantities are available within eight to 12 weeks.
