IX2113B Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IX2113B is a half-bridge gate driver IC manufactured by IXYS Integrated Circuits Division, designed for driving IGBT and MOSFET devices in power management applications. This device features independent dual-channel configuration with non-inverting inputs and is packaged in a 16-SOIC surface mount package.

The IX2113B is classified as obsolete. Identifying suitable substitute components is necessary to maintain design continuity and ensure component availability for new production runs and system maintenance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IX2113B is determined by the following critical parameters:

• Package Compatibility: Both devices must use 16-SOIC surface mount packaging with identical physical dimensions (0.295", 7.50mm Width)
• Functional Configuration: Driver topology must support half-bridge or compatible high-side/low-side gate driving with dual independent channels
• Input Logic: Non-inverting input type required for direct signal compatibility
• Supply Voltage Range: Operating supply voltage must overlap with or encompass the 10V ~ 20V requirement
• Logic Threshold Levels: VIL and VIH must match 6V and 9.5V specifications
• Output Current Capability: Peak source and sink current must meet or exceed 2A minimum requirement
• Bootstrap Voltage Rating: High-side voltage capability must support minimum 600V operation
• Regulatory Compliance: ROHS3 compliance required for environmental standards

The FAN73912MX from onsemi meets these substitution criteria while offering enhanced specifications in certain parameters.

Engineering Selection Recommendations

The FAN73912MX is a direct functional substitute for the IX2113B based on the following engineering criteria:

Compliance and Availability: The FAN73912MX maintains ROHS3 compliance and is actively produced by onsemi, ensuring long-term component availability compared to the obsolete IX2113B status.

Package Compatibility: Both devices use identical 16-SOIC packaging, enabling direct PCB layout compatibility without redesign.

Electrical Compatibility: The FAN73912MX meets all critical electrical parameters including supply voltage overlap (12V ~ 20V), matching logic thresholds (6V, 9.5V), and non-inverting input configuration. The substitute provides equal or superior performance in peak output current and bootstrap voltage rating.

Operating Temperature Consideration: The IX2113B supports operation to 150°C junction temperature, while the FAN73912MX is rated to 125°C. Applications requiring operation above 125°C require thermal analysis to confirm FAN73912MX suitability.

Moisture Handling: The FAN73912MX has MSL 3 (168 hours) compared to IX2113B MSL 1 (unlimited). Storage and handling procedures must account for this moisture sensitivity level difference.

Frequently Asked Questions (FAQ)

Q: Can the FAN73912MX directly replace the IX2113B without PCB modifications?

A: Yes. Both devices use identical 16-SOIC packaging with matching pin configurations and non-inverting input logic. Direct socket substitution is possible without PCB layout changes.

Q: What is the key difference in supply voltage range between these devices?

A: The IX2113B operates from 10V to 20V, while the FAN73912MX operates from 12V to 20V. Applications using supply voltages between 10V and 12V require the IX2113B or alternative components. For supplies at 12V and above, both devices are compatible.

Q: How does the operating temperature range affect substitution?

A: The IX2113B supports -40°C to 150°C junction temperature, while the FAN73912MX supports -40°C to 125°C. For applications operating above 125°C, verify that thermal design maintains the FAN73912MX junction temperature within specification, or select an alternative component rated to higher temperatures.

Q: Are the logic input thresholds identical?

A: Yes. Both the IX2113B and FAN73912MX have identical logic voltage thresholds: VIL = 6V and VIH = 9.5V. Signal conditioning circuits designed for the IX2113B require no modification for the FAN73912MX.

Q: What is the significance of the different Moisture Sensitivity Levels?

A: The IX2113B has MSL 1 (unlimited moisture exposure tolerance), while the FAN73912MX has MSL 3 (168-hour limit). The FAN73912MX requires controlled storage conditions and has a limited shelf life after package opening. Verify that component handling and storage procedures comply with MSL 3 requirements.

Q: Does the FAN73912MX support P-Channel MOSFET driving like the IX2113B?

A: The FAN73912MX is specified for IGBT and N-Channel MOSFET driving. Applications requiring P-Channel MOSFET gate drive must verify compatibility or select alternative components explicitly rated for P-Channel devices.

Q: What is the bootstrap voltage rating difference?

A: The IX2113B is rated for 600V maximum bootstrap voltage, while the FAN73912MX is rated for 1200V. The FAN73912MX provides higher voltage margin for high-side gate drive applications. Both devices are suitable for applications within the 600V specification.
