3A Peak Output Current
Wide Operating Voltage Range: 4.5V to 35V
-40°C to +125°C Operating Temperature Range
Latch-up Protected to 3A
Fast Rise and Fall Times
Low Power Consumption
3-Ampere Dual Low-Side
Ultrafast MOSFET Drivers
Description
The IX4423, IX4424, and IX4425 are dual high-speed,
low-side gate drivers. Each of the two outputs can
source and sink 3A 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 IX4423, IX4424,
and IX4425 ideal for high-frequency and high-power
applications.
The IX4423 is configured as a dual inverting driver;
the IX4424 is configured as a dual non-inverting
driver; and the IX4425 is configured with one inverting
driver and one non-inverting driver. All three devices
are available in a standard 8-pin SOIC package.
