LISTED UNDER:

IXYS Integrated Circuits Division announces the immediate availability of the IX4426, IX4427, and IX4428 low-cost dual low-side gate driver ICs.  Each of the IX4426/7/8 outputs are capable of sourcing and sinking 1.5A, and they have a wide operating voltage range of 4.5V to 35V, which is much higher than competitive parts.  The inputs of each driver are TTL and CMOS compatible, and are virtually immune to latch-up.  The IX4426/7/8 are specified with an operating temperature range of -40°C to +125°C.

The IX4426 is configured as a dual inverting driver; the IX4427 is configured as a dual non-inverting driver; and the IX4428 is configured with one inverting and one non-inverting driver.  All versions have an industry standard pinout, and are available in an 8-lead SOIC package.  The IX4426N, IX4427N and IX4428N devices are lower cost drop in replacements for various competitive 1.5A gate drivers, while providing a much higher 35V operating capability.

The low cost IX4426/7/8 are well suited for driving power MOSFETS in switching power supplies, motor controls, and DC to DC converters.  The IX4426/7/8 are added to IXYS ICD's extensive gate driver IC portfolio, which includes its popular IXD_600 series of low side gate driver ICs.  The IXD_600 series offers gate drivers rated from 2A up to 30A

These families of gate drivers are compatible with IXYS’ Zilog MCUs for digital power control, with IXYS’ families of rugged power MOSFETs and IGBTs. The IX446/7/8 devices are available in production quantities.

Pricing and availability

The IX446/7/8 are available in production quantities. Pricing for OEM quantities of 25KU is $0.32 each.
