Littelfuse has launched the IX4352NE, a low-side gate driver IC which is especially well suited to driving silicon carbide (SiC) MOSFETs and high-power IGBTs in industrial applications.
The IX4352NE features 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 selectable negative gate-drive bias for improved immunity to transient voltage spikes while enabling faster turn-off. The internal regulator 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 enables direct interfacing to a host microcontroller.
Operating from an input voltage of up to 35 V, this driver offers exceptional flexibility and performance.
The IX4352NE is an improved, pin-compatible version of the IX4351NE, offering:
