IX2113BTR Half-Bridge Gate Driver IC Equivalent & Substitute Parts

Part Overview

The IX2113BTR is a half-bridge gate driver IC manufactured by IXYS Integrated Circuits Division, designed for driving IGBT and MOSFET configurations in power management applications. This device features independent channel control with 2A peak output current capability and operates across a 10V to 20V supply voltage range. The product is currently classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations where legacy component replacement is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IX2113BTR is determined by the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Package compatibility: 16-SOIC form factor (0.295", 7.50mm Width)
• Driven configuration: Half-bridge or high-side/low-side topology with 2 independent drivers
• Input control: Non-inverting logic
• Supply voltage range: Minimum 10V operation capability
• Peak output current: Minimum 2A source and sink capability
• Gate type support: IGBT and MOSFET compatibility

Secondary Compatibility Factors:

• Logic voltage thresholds (VIL, VIH)
• Bootstrap voltage rating
• Operating temperature range
• RoHS and regulatory compliance

The FAN73912MX qualifies as a functional substitute based on matching package geometry, dual-driver configuration, non-inverting input control, compatible supply voltage range (12V ~ 20V overlaps the upper operating range), and equivalent peak output current specifications (2A source, 3A sink exceeds minimum requirements).

Parameter Comparison

Engineering Selection Recommendations

For Legacy System Maintenance: The FAN73912MX serves as the primary substitute for IX2113BTR replacement in existing designs. Both devices share identical package geometry and pin-compatible 16-SOIC form factor, enabling direct PCB layout compatibility without redesign. The matching non-inverting input control and dual-driver configuration preserve signal integrity and control logic without firmware or software modification.

Supply Voltage Consideration: Applications operating at supply voltages below 12V require design verification. The IX2113BTR operates from 10V minimum, while the FAN73912MX minimum is 12V. Systems designed for 10V to 12V operation must confirm adequate headroom or implement voltage regulation adjustments.

Temperature Operating Range: The IX2113BTR supports junction temperatures to 150°C, while the FAN73912MX is rated to 125°C maximum. Thermal analysis is required for applications approaching or exceeding 125°C to ensure the substitute meets reliability requirements.

Regulatory and Compliance Status: Both devices maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements. The FAN73912MX active product status ensures ongoing manufacturer support, documentation availability, and supply chain continuity compared to the obsolete IX2113BTR.

Moisture Handling: The FAN73912MX carries MSL 3 (168 hours) versus the IX2113BTR MSL 1 (unlimited). Manufacturing and storage processes must implement controlled humidity environments and desiccant packaging protocols for the substitute device.

Frequently Asked Questions (FAQ)

Q: Can the FAN73912MX directly replace the IX2113BTR without PCB modifications?

A: Yes. Both devices use identical 16-SOIC packaging with matching pin assignments for half-bridge gate driver applications. Direct PCB substitution is possible without layout changes.

Q: What is the minimum supply voltage for the FAN73912MX?

A: The FAN73912MX operates from 12V minimum supply voltage. The IX2113BTR operates from 10V. Applications requiring 10V to 12V operation must verify adequate supply voltage availability or implement voltage regulation.

Q: Are the logic input thresholds identical between these devices?

A: Yes. Both the IX2113BTR and FAN73912MX share identical logic voltage thresholds: VIL = 6V and VIH = 9.5V. Control signal conditioning remains unchanged during substitution.

Q: Does the higher bootstrap voltage rating of the FAN73912MX affect compatibility?

A: No. The FAN73912MX 1200V bootstrap rating exceeds the IX2113BTR 600V specification. Higher ratings are backward compatible and do not introduce incompatibility in systems designed for 600V operation.

Q: What are the storage and handling requirements for the FAN73912MX?

A: The FAN73912MX carries MSL 3 classification, requiring storage at controlled humidity (≤60% RH) for up to 168 hours after package opening. The IX2113BTR MSL 1 classification permits unlimited storage without humidity control. Implement appropriate desiccant packaging and environmental controls during manufacturing and assembly.

Q: Is the FAN73912MX suitable for applications requiring 150°C junction temperature operation?

A: No. The FAN73912MX maximum junction temperature is 125°C. Applications requiring sustained operation above 125°C must implement thermal management modifications or identify alternative devices with higher temperature ratings.

Q: What is the product availability status for each device?

A: The IX2113BTR is classified as obsolete with limited remaining inventory. The FAN73912MX is an active product with established supply chain availability through multiple distributors, ensuring long-term sourcing reliability.
