IX442x 1.5A Dual Low-Side Ultrafast Gate Driver IXYS Integrated Circuits IX442x are dual high-speed, low-side gate drivers. Each of the two outputs can source and sink 1.5A of peak current with rise and fall times of less than 10ns. The inputs of each driver are TTL and CMOS compatible, and are virtually immune to latch-up. Low propagation delay times and fast, matched rise and fall times make the IXYS IX4426, IX4427, and IX4428 ideal for high-frequency and high-power applications.
