Littelfuse, Inc. announced 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. Its superior performance makes it ideal for demanding power electronics applications in the electric vehicle, industrial, alternate energy, smart home, and building automation markets. With its comprehensive features, the IX4352NE simplifies circuit design and offers a higher level of integration. Built-in protection features such as desaturation detection (DESAT) with soft shutdown sink driver, Under Voltage Lockout (UVLO), and thermal shutdown (TSD) ensure the protection of the power device and the gate driver. 

The key differentiator of the IX4352NE lies in its separate 9 A source and sink outputs, which enable tailored turn-on and turn-off timing while minimizing switching losses. An internal negative charge regulator also provides a user-selectable negative gate drive bias for improved dV/dt immunity and faster turn-off. With an operating voltage range (VDD - VSS) of up to 35 V, this driver offers exceptional flexibility and performance. One of the standout features of the IX4352NE is its internal negative charge pump regulator, which eliminates the need for an external auxiliary power supply or DC/DC converter. This feature is particularly valuable for turning off SiC MOSFETs, saving valuable space typically required for external logic level translator circuitry. The logic input's compatibility with standard TTL or CMOS logic levels further enhances space-saving capabilities.
