Littelfuse Introduces IX4341 and IX4342 Dual 5 Ampere Low-Side MOSFET Gate Drivers for High-Frequency Applications

IX4341 and IX4342 Low-side Gate Driver

Expansion of driver series addresses a broad spectrum of industrial, building automation, data center, and renewable energy applications

CHICAGO, September 04, 2024 -- Littelfuse, Inc. (NASDAQ: LFUS), an industrial technology manufacturing company empowering a sustainable, connected, and safer world, is proud to announce the launch of the IX4341 and IX4342 dual 5 ampere low-side MOSFET gate drivers. These gate drivers are specifically designed for driving MOSFETs and complete the existing IX434x driver series by adding the remaining two logic input versions. The IX434x series now consists of dual non-inverting, dual inverting, and non-inverting and inverting input versions, providing customers with a comprehensive range of options.

The IX4341 and IX4342 drivers’ short propagation delay times of 16 nanoseconds and brief rise and fall times of 7 nanoseconds make them ideal for high-frequency applications. Additionally, for higher current requirements, electronics designers can parallel the two channels of the IX4340 and IX4341 devices to form a single 10 A driver, providing flexibility and scalability.

A notable feature of the IX434x drivers is their compatibility with TTL and CMOS logic inputs, enabling direct interfacing with most controllers. Furthermore, each output has an independent ENABLE function and under-voltage lockout circuitry (UVLO) to ensure reliable and safe operation. In case of eventual insufficient supply voltage, the gate driver output is asserted low, turning the external power device off.

The IX4341 and IX4342 dual 5 A low-side gate drivers find applications in various markets, including:

  • general industrial and electrical equipment,
  • appliances,
  • building solutions,
  • data centers,
  • energy storage, and
  • renewable energy.

These low-side MOSFET gate drivers are ideally suited for numerous industrial applications such as:

  • switch-mode power supplies,
  • DC-DC converters,
  • motor controllers, and
  • power converters.

The IX434x devices are available in standard 8-pin SOIC, thermally enhanced 8-pin SOIC, and 3×3 mm² MSOP packages, offering customers a range of options to suit their specific needs.

“This new series of dual five-ampere low-side gate drivers simplify circuit design with its high level of integration and compatibility with various logic input versions," said June Zhang, Product Manager, Integrated Circuits Division, Semiconductor Business Unit, at Littelfuse. "With these drivers, customers can expect enhanced performance and protection for their power devices.”

The IX434x dual 5 A low-side gate drivers find applications in various industries, including general industrial and electrical equipment, appliances, building solutions, data centers, energy storage, and renewable energy.

They serve as a direct drop-in alternative to similar available drivers, providing customers with industry-standard options to meet their supply demands.
