IX4426/7/8M Low-Side Gate Drivers

The IX4426/7/8M are the popular IXYS, a Littelfuse Technology low-cost 4426/7/8 dual low-side gate drivers packaged in a small 3 x 3 DFN package. The two outputs of the IX4426/7/8M are each capable of sourcing and sinking 1.5 A, and can switch a 1000 pF in less than 10 ns. For higher current requirements, the two outputs can be paralleled for a total of 3 A peak sourcing and sinking current.

The IX4426/7/8M have a wide operating voltage range of 4.5 V to 35 V, which is much higher than competitive parts. The inputs are TTL and CMOS compatible and are virtually immune to latch-up.

The IX4426M is configured as a dual inverting driver, the IX4427M is configured as a dual non-inverting driver, and the IX4428M configured with one inverting and one non-inverting driver.
