IXDN409SI

Overview

The IXDN409SI is a low-side gate driver from the IXD_409 series by IXYS Integrated Circuits. It features a single non-inverting output capable of delivering 9 A peak current. The device operates on a supply voltage range of 4.5 V to 35 V and utilizes CMOS/TTL compatible logic inputs. Key electrical parameters include a rise time of 22 ns, a fall time of 15 ns, and maximum delay times of 75 ns for both turn-on and turn-off. It functions within an operating temperature range of -40°C to +125°C and is housed in an 8-SOIC surface-mount package.

Feature Summary

• High-speed switching capability designed for driving large MOSFETs and IGBTs
• Non-inverting configuration with single driver output
• CMOS and TTL logic input compatibility

Applications

• Power supply circuits requiring fast MOSFET switching
• IGBT gate drive applications
• Motor control systems

Procurement Notes

Verify component authenticity through authorized IXYS distributors or Littelfuse channels. Confirm RoHS compliance status via official datasheets. Ensure the 8-SOIC package matches PCB footprint requirements. Check for specific ordering suffixes if available. Validate lead times and availability directly with suppliers as stock levels fluctuate.

Selection Notes

Select this component for applications requiring high peak current drive (9 A) with low propagation delays. The non-inverting logic simplifies control interface design compared to inverting alternatives. Consider the wide supply voltage range (up to 35 V) for flexibility in various power stages. Evaluate thermal performance within the specified -40°C to +125°C range for industrial environments.

Part Context

The IXDN409SI belongs to the IXD_409 family of high-speed, high-current gate drivers. This series includes variants like IXDD409SI and IXDI409SIA, which share similar core specifications but may differ in pinout or packaging. These drivers are engineered to minimize switching losses in power electronics by providing robust gate charge delivery.

Replacement Considerations

Potential substitutes include IXDI409SIA and IXDD409SI from the same manufacturer. Verify pin compatibility and logical inversion status before substitution. Cross-reference electrical parameters such as peak current and delay times to ensure equivalent performance in the target circuit.
