Simplifying Gate Drive Design: Littelfuse Releases Compact IXD0579M High- and Low-Side Driver IC

Littelfuse has unveiled the IXD0579M, a new high-speed gate driver IC that combines high performance with board design simplicity. Specifically developed for driving N-channel MOSFETs or IGBTs in half-bridge configurations, the IXD0579M integrates a bootstrap diode and current-limiting resistor directly into its small 3×3 mm² TDFN-10 package—saving space and reducing bill of materials (BOM) complexity for engineers working on brushless motors, battery-powered tools, DC-DC converters, and compact industrial systems.

The IXD0579M operates from a wide supply range of 6.5 V to 18 V and features 1.5 A source and 2.5 A sink output drive capabilities. It also offers built-in protections and compatibility with TTL and CMOS logic levels down to 3.3 V. With ultra-low standby current (<1 µA) and robust thermal tolerance from –40 °C to +125 °C, the IC is optimized for energy-efficient, high-frequency switching designs.

Why This Release Matters

In an increasingly supply-constrained world, the ability to drop in an alternative without redesigning the PCB can mean the difference between staying on schedule and missing a production window. The IXD0579M offers exactly that kind of flexibility—serving as a direct drop-in replacement for existing industry-standard gate drivers.

“For engineers, this isn’t just about performance—it’s about security,” said June Zhang, Product Manager at Littelfuse. “The IXD0579M helps ensure continuity of supply, simplifies circuit design, and eliminates the need for additional discrete components that take up board space and increase cost.”

Ideal Use Cases

This driver is tailored for designs that demand compact form factors and reliable high-speed switching, such as:

• BLDC motor drives – enabling precise, efficient motor control

• Battery-operated power tools – where energy efficiency and board space are at a premium

• DC-DC converters and industrial power supplies – requiring robust and compact gate control

• General-purpose industrial and electrical systems – where multiple source components reduce procurement risk

Availability

The IXD0579M is offered in a TDFN-10 package and ships in tape and reel format (3,000 units per reel). Samples are available through Littelfuse’s global network of authorized distributors.

For engineers looking to streamline their gate drive designs while keeping options open in a volatile supply chain, the Littelfuse IXD0579M presents a smart, forward-thinking solution.
