IX4426-IX4427-IX4428 1.5-mpere Dual Low-Side Ultrafast MOSFET Drivers Features 1.5 Peak Output Current Wide Operating Voltage Range: 4.5V to 35V -4 C to +125 C Operating Temperature Range Latch-up Protected to 1.5 TTL and CMOS Compatible Inputs Fast Rise and Fall Times Low Power Consumption pplications MOSFET Driver Switching Power Supplies Motor Controls DC to DC Converters Pulse Transformer Driver Description The IX4426, IX4427, and IX4428 are dual high-speed, low-side gate drivers. Each of the two outputs can source and sink 1.5 of peak current with rise and fall times of less than 1ns. 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 IX4426, IX4427, and IX4428 ideal for high-frequency and high-power applications. 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 driver and one non-inverting driver. ll three devices are available in a standard 8-pin SOIC package (N suffix) and an 8-pin DFN package (M suffix).

5 Manufacturing Information 5.1 Moisture Sensitivity ll plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated Circuits Division classifies its plastic encapsulated devices for moisture sensitivity according to the latest version of the joint industry standard, IPC/JEDEC J-STD-2, in force at the time of product evaluation. We test all of our products to the maximum conditions set forth in the standard, and guarantee proper operation of our devices when handled according to the limitations and information in that standard as well as to any limitations set forth in the information or standards referenced below. Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced product performance, reduction of operable life, and/or reduction of overall reliability. This product carries a Moisture Sensitivity Level (MSL) classification as shown below, and should be handled according to the requirements of the latest version of the joint industry standard IPC/JEDEC J-STD-33. Device Moisture Sensitivity Level (MSL) Classification IX4426 / IX4427 / IX4428 ll Versions MSL 1 5.2 ESD Sensitivity This product is ESD Sensitive, and should be handled according to the industry standard JESD-625. 5.3 Reflow Profile Provided in the table below is the Classification Temperature (T C ) of this product and the maximum dwell time the body temperature of this device may be (T C - 5)ºC or greater. The classification temperature sets the Maximum Body Temperature allowed for this device during lead-free reflow processes. For through-hole devices, and any other processes, the guidelines of J-STD-2 must be observed. Device Classification Temperature (T C ) Dwell Time (t p ) Max Reflow Cycles IX4426 / IX4427 / IX4428 ll Versions 26 C 3 seconds 3 5.4 Board Wash IXYS Integrated Circuits Division recommends the use of no-clean flux formulations. Board washing to reduce or remove flux residue following the solder reflow process is acceptable provided proper precautions are taken to prevent damage to the device. These precautions include but are not limited to: using a low pressure wash and providing a follow up bake cycle sufficient to remove any moisture trapped within the device due to the washing process. Due to the variability of the wash parameters used to clean the board, determination of the bake temperature and duration necessary to remove the moisture trapped within the package is the responsibility of the user (assembler). Cleaning or drying methods that employ ultrasonic energy may damage the device and should not be used. dditionally, the device must not be exposed to flux or solvents that are Chlorine- or Fluorine-based.
