Gate driver boosts reliability in high-power designs

Featuring 2.5-kV capacitive isolation, the Littelfuse IX3407B gate driver improves signal integrity and safety in motor drives, inverters, and industrial power supplies. The single-channel, galvanically isolated driver provides low propagation delay, high common-mode transient immunity, and enhanced thermal stability across switching frequencies and temperatures.

The IX3407B gate driver delivers up to 7 A peak source and sink current through separate output pins. Typical turn-on and turn-off times are 154 ns and 162 ns, respectively, with rise and fall times of 10 ns. It achieves 150-kV/µs common-mode transient immunity at 700 V.

Input supply voltage ranges from 3.1 V to 17 V, while the driver-side supply operates from 13 V to 35 V. TTL/CMOS logic compatibility with 3.3-V thresholds and input voltage tolerance up to V_CC support a wide range of control logic devices. Active shutdown and undervoltage lockout safeguard against fault conditions.

The IX3407B is offered in a wide-body SOIC-8 package. Samples are available through Littelfuse authorized distributors.
