The IX4426, IX4427, and IX4428 are low-cost dual low-side gate driver ICs from the IXYS Integrated Circuits Division. 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 drivers are specified with an operating temperature range of -40C to +125C.
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 drivers are well suited for driving power MOSFETS and IGBTs in switching power supplies, motor controls, and DC to DC converters. The IX4426/7/8 drivers 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 expanded range of gate drivers offer IXYS customers a wide variety of gate drivers that are compatible for direct digital drive with the Zilog line of MCUs, for digital power control applications. The IX446/7/8 drivers are available in production quantities.
