Littelfuse announces the launch of the IX4352NE Low-side SiC MOSFET and IGBT Gate Driver. This innovative driver is specifically designed to drive Silicon Carbide (SiC) MOSFETs and high-power Insulated Gate Bipolar Transistors (IGBTs) in industrial applications.
The IX4352NE Low-side SiC MOSFET and IGBT Gate Driver distinct 9-amp source and sink outputs allows:
- Customized turn-on and turn-off time while reducing switching losses, this sets it apart.
- For better dV/dt immunity and quicker turn-off, an inbuilt negative charge regulator also offers a user-selectable negative gate drive bias.
- With a maximum working voltage range of 35 V (VDD – VSS), this driver provides outstanding performance and versatility.
One of the important features of IX4352NE is its integrated negative charge pump regulator, which eliminates the need for a separate auxiliary power supply or DC/DC converter.
By turning off SiC MOSFETs, this capability is highly helpful in saving space that would otherwise be required for external logic level translator circuitry. Space-saving capabilities are further enhanced by the logic input’s typical TTL or CMOS logic level compatibility.
SiC MOSFETs are best driven by the IX4352NE in a variety of industrial applications, including:
- on-board and off-board chargers,
- Power Factor Correction (PFC),
- DC/DC converters,
- motor controllers, and
- industrial power inverters.
Due to its exceptional performance, it is perfect for high-demanding power electronics applications in the markets for smart homes, industrial, alternative energy, electric vehicles, and building automation.
The IX4352NE offers a better degree of integration and makes circuit design simpler with its extensive feature set. The power device and the gate driver are protected by built-in protection features including thermal shutdown (TSD), under voltage lockout (UVLO), and desaturation detection (DESAT) with soft shutdown sink driver.
To improve safety and dependability, the inbuilt open-drain FAULT output alerts the microcontroller to a fault situation. In addition, the IX4352NE improves circuit density and conserves important PCB area, both of which boost system efficiency.
Notable improvements over the existing IX4351NE include:
- A safe DESAT-initiated soft turn-off.
- A thermal shutdown with high threshold accuracy.
- The charge pump’s ability to operate during thermal shutdown.
Because the new IX4352NE Low-side SiC MOSFET and IGBT Gate Driver is pin-compatible, it can be easily swapped out with the 2020-released Littelfuse IX4351NE in designs that call for it.
“The IX4352NE extends our broad range of low-side gate drivers with a new 9?A sink/source driver, simplifying the gate drive circuitry needed for SiC MOSFETs,” commented June Zhang, Product Manager, Integrated Circuits Division (SBU) at Littelfuse. “Its various built-in protection features and integrated charge pump provide an adjustable negative gate drive voltage for improved dV/dt immunity and faster turn-off. As a result, it can be used to drive any SiC MOSFET or power IGBT, whether it is a Littelfuse device or any other similar component available on the market.”
