IXDN630YI

Overview

The Littelfuse IXDN630YI is a high-speed, low-side gate driver designed for power MOSFETs and IGBTs. It delivers 30A peak source/sink current with rise/fall times under 20ns. Operating voltage ranges from 9V to 35V. Propagation delay is low, with matched transition times. The device features UVLO (12.5V threshold), enable control, and cross-conduction protection. It operates from -40°C to +125°C in a TO-263-5 package.

Feature Summary

• Provides 30A peak drive current for rapid switching
• Includes under-voltage lockout and enable functionality
• Eliminates cross-conduction and latch-up risks
• Supports extended industrial temperature ranges

Applications

• High-frequency motor control systems
• Industrial power management circuits
• IGBT and MOSFET gate driving stages

Procurement Notes

Verify the specific suffix 'MYI' or 'YI' against the manufacturer's official datasheet to confirm pinout compatibility and electrical thresholds. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the lot date code to ensure freshness. Confirm that the TO-263-5 package dimensions match your PCB footprint exactly before finalizing procurement orders.

Selection Notes

Select this driver when high peak current capability is required for fast-switching power devices. The non-inverting configuration suits applications where signal polarity must be preserved. Consider the UVLO threshold and operating voltage range relative to the system supply. The extended temperature range makes it suitable for harsh industrial environments compared to commercial-grade alternatives.

Part Context

This component belongs to the IXD_630 series of high-speed gate drivers from Littelfuse/IXYS. The series includes variants like IXDD630 and IXDI630, differing primarily in inversion logic and enable pin configurations. All share similar electrical characteristics optimized for driving modern power semiconductors efficiently.

Replacement Considerations

Direct substitutes include other parts within the IXD_630 family, such as IXDD630 or IXDI630, provided logical inversion and enable pin requirements align. Verify pin-to-pin compatibility and electrical specifications before substitution.

FAQ

What is the UVLO threshold for the IXDN630YI?

The under-voltage lockout threshold is typically 12.5V, ensuring the output remains low until sufficient supply voltage is applied.

Does the IXDN630YI support negative input swings?

Yes, the logic input can tolerate negative swings up to 5V, enhancing noise immunity in noisy environments.
