New Low Cost Dual 5A Gate Driver IC in power MSOP package Introduced


The IX4340UE is capable of driving most IXYS Power MOSFETs and IGBTs

IXYS Integrated Ciruits Division, now part of Littelfuse, Inc., announces the immediate availability of the IX4340UE low-cost Dual 5 A Gate Driver IC. The IX4340UE features two high current outputs, both capable of sourcing and sinking up to 5 A. Both outputs have an absolute maximum voltage rating of 20 V. With matched propagation delays, the identical output drivers can be connected in parallel for higher current applications. The logic inputs are TTL and CMOS logic compatible, and there is an Enable function for each output. Under voltage lockout circuitry prevents the high side source driver from conducting until there is sufficient supply voltage.


Fast propagation delay times (16 ns typical), and fast rise and fall times (7 ns typical) make the IX4340UE well suited for high frequency applications. The IX4340UE has an extended operating temperature range of –40 °C to +125 °C, and has a ±4 kV ESD rating (human body model). This gate driver is supplied in a thermally enhanced 8-lead 3×3 mm MSOP package.

The low cost IX4340UE is well suited for driving power MOSFETs and IGBTs in high power SMPS applications, power inverters, DC to DC converters, and motor controls. For even higher gate drive requirements, IXYS ICD offers 14 A (IXD_614 series) and 30 A (IXD_630 series) gate driver ICs.


The IX4340UE is in volume production, and samples are available at any authorized IXYS ICD distributors. IX4340UE devices are in 8-Pin MSOP with an Exposed Thermal Pad in quantities of 100 pieces per tube, and IX4340UETR devices are on tape and reel in quantites of 5,000 peices per reel.
