IXDI414YI Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IXDI414YI is a low-side gate driver IC manufactured by IXYS, designed for driving IGBT and MOSFET gates in power management applications. This inverting gate driver operates across a 4.5V to 35V supply voltage range and delivers 14A peak output current in both source and sink configurations. The device is packaged in TO-263-5 (D2PAK) surface mount format.

The IXDI414YI is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain reliability, and support ongoing production requirements for applications utilizing this gate driver topology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IXDI414YI is determined by strict alignment across the following critical parameters:

• Driven configuration must remain low-side
• Single channel, single driver topology must be maintained
• Gate type compatibility with IGBT and MOSFET devices must be preserved
• Supply voltage range must encompass or match 4.5V ~ 35V
• Peak output current must meet or exceed 14A (source and sink)
• Input type must remain inverting
• Operating temperature range must cover -55°C ~ 150°C
• Package must be TO-263-5 surface mount format

The IXDI614YI meets all substitution criteria and is classified as an equivalent part for the IXDI414YI.

Parameter Comparison

Engineering Selection Recommendations

The IXDI614YI manufactured by Littelfuse is a direct functional equivalent to the IXDI414YI. Both devices share identical electrical specifications for supply voltage, output current, gate type support, and operating temperature range. The IXDI614YI is currently in active production status, ensuring long-term supply availability compared to the obsolete IXDI414YI.

The IXDI614YI carries ROHS3 compliance certification, meeting current environmental and regulatory requirements. The higher moisture sensitivity level (MSL 3 versus MSL 1) requires adherence to standard moisture control procedures during storage and handling, consistent with industry practice for surface mount components.

Minor timing variations exist between the two devices: the IXDI614YI exhibits slightly longer rise time (25ns versus 22ns) and faster fall time (18ns versus 20ns). These differences remain within acceptable tolerances for low-side gate driver applications and do not impact functional compatibility in standard IGBT and MOSFET switching circuits.

Frequently Asked Questions (FAQ)

Q: Can the IXDI614YI directly replace the IXDI414YI in existing designs?

A: Yes. Both devices are single-channel, low-side gate drivers with identical supply voltage ranges (4.5V ~ 35V), peak output current (14A source and sink), and operating temperature specifications (-55°C ~ 150°C). The TO-263-5 package footprint is identical, enabling direct PCB substitution.

Q: What is the significance of the different MSL ratings?

A: The IXDI414YI carries MSL 1 (unlimited moisture exposure tolerance), while the IXDI614YI carries MSL 3 (168-hour moisture exposure limit). MSL 3 requires standard moisture control during component storage and handling. This does not affect electrical performance or long-term reliability when proper storage conditions are maintained.

Q: Are there differences in logic voltage thresholds?

A: The IXDI414YI specifies VIH at 4.6V, while the IXDI614YI specifies VIH at 3V. Both maintain VIL at 0.8V. The IXDI614YI's lower VIH threshold provides improved compatibility with lower-voltage logic signal sources while maintaining robust noise immunity.

Q: How do the timing specifications compare?

A: The IXDI414YI exhibits 22ns rise time and 20ns fall time. The IXDI614YI exhibits 25ns rise time and 18ns fall time. These variations are minor and do not impact gate driver functionality in standard power conversion applications. Switching frequency and dead-time requirements remain unaffected.

Q: What compliance certifications apply to the IXDI614YI?

A: The IXDI614YI is ROHS3 compliant and carries REACH Unaffected status. Both devices share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications for export and tariff purposes.
