TC4423VOE Low-Side Gate Driver IC Equivalent & Substitute Parts

Part Overview

The TC4423VOE is an active low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in power management applications. This inverting gate driver operates across a 4.5V to 18V supply voltage range with independent dual-channel configuration and 3A peak output current capability. The device is currently in active production status with 916 units in stock. Alternative part numbers are necessary to address packaging preferences, inventory availability, or supply chain continuity requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TC4423VOE is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Driven configuration: Low-Side
• Number of drivers: 2 independent channels
• Gate type: N-Channel and P-Channel MOSFET compatibility
• Supply voltage range: 4.5V ~ 18V
• Logic voltage thresholds: VIL 0.8V, VIH 2.4V
• Peak output current: 3A source and sink capability
• Input type: Inverting
• Operating temperature range: -40°C ~ 150°C (TJ)

Mechanical Equivalence Requirements:

• Package type: 16-SOIC
• Package dimensions: 0.295" × 7.50mm width
• Mounting type: Surface Mount

Compliance Requirements:

• RoHS3 compliance
• Active product status

The MIC4423YWM-TR variant meets all electrical and mechanical equivalence criteria. The primary distinction is packaging format (Tape & Reel versus Tube) and minor timing parameter variations within acceptable operational margins.

Parameter Comparison

Engineering Selection Recommendations

Both TC4423VOE and MIC4423YWM-TR are manufactured by Microchip Technology and maintain active product status with ROHS3 compliance. Selection between these parts should be based on the following factors:

TC4423VOE (Tube Packaging): Select this part number when tube packaging is required for manual assembly processes or when inventory management systems are configured for tube format distribution. MSL rating of 1 provides unlimited shelf life without moisture control requirements.

MIC4423YWM-TR (Tape & Reel Packaging): Select this part number for automated pick-and-place assembly operations or when tape and reel format is specified in procurement requirements. This format is standard for high-volume manufacturing environments. MSL rating of 2 requires storage within controlled humidity conditions for a 12-month period.

The timing parameter variation (rise/fall time: 23ns/25ns versus 28ns/32ns) remains within acceptable operational margins for low-side gate driver applications and does not constitute a functional limitation for standard MOSFET switching applications.

Frequently Asked Questions (FAQ)

Q: Can MIC4423YWM-TR be used as a direct replacement for TC4423VOE in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent with identical supply voltage ranges, output current ratings, logic thresholds, and package dimensions. The primary difference is packaging format (Tape & Reel versus Tube) and minor timing characteristics that remain within acceptable operational parameters.

Q: What is the significance of the different Moisture Sensitivity Level (MSL) ratings?

A: TC4423VOE carries MSL 1 (unlimited shelf life), while MIC4423YWM-TR carries MSL 2 (1-year shelf life under controlled humidity). MSL 2 components require storage in humidity-controlled environments (typically 30% to 60% relative humidity) and must be used within 12 months of the manufacturing date. MSL 1 components have no such restrictions.

Q: Are there any timing performance differences between these parts?

A: Rise and fall times differ slightly: TC4423VOE specifies 23ns/25ns while MIC4423YWM-TR specifies 28ns/32ns. Both values are typical specifications and remain within acceptable switching performance for low-side gate driver applications. Design margins should account for these variations if timing-critical applications are involved.

Q: Which packaging format should be selected for automated assembly?

A: MIC4423YWM-TR in Tape & Reel format is the standard choice for automated pick-and-place assembly operations. TC4423VOE in Tube format is suitable for manual assembly or when tape and reel format is not available.

Q: Do both parts meet the same compliance standards?

A: Yes. Both TC4423VOE and MIC4423YWM-TR are ROHS3 compliant, REACH unaffected, and carry identical ECCN and HTSUS classifications. Both maintain active product status with Microchip Technology.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes, provided that the assembly process accommodates the packaging format. The 16-SOIC package dimensions are identical, and the electrical characteristics are equivalent. Packaging format selection should align with the assembly equipment and procurement workflow.
