TC4432VOA Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The TC4432VOA is an active, high-side or low-side gate driver IC manufactured by Microchip Technology, designed for driving N-Channel and P-Channel MOSFETs in power management applications. This single-channel, non-inverting gate driver operates across a 4.5V to 30V supply voltage range and delivers 1.5A peak output current in both source and sink configurations. The device is packaged in an 8-SOIC surface mount package and is ROHS3 compliant. Substitute parts are identified based on matching electrical specifications, mechanical compatibility, and packaging options to support procurement flexibility and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TC4432VOA is determined by strict equivalence across the following critical parameters:

• Electrical Specifications: Supply voltage range (4.5V ~ 30V), logic voltage thresholds (VIL 0.8V, VIH 2.4V), peak output current (1.5A source and sink), rise/fall time (25ns, 33ns), and operating temperature range (-40°C ~ 150°C).
• Functional Configuration: High-side or low-side driven configuration, single-channel topology, non-inverting input type, and N-Channel/P-Channel MOSFET gate drive capability.
• Mechanical Compatibility: 8-SOIC surface mount package with 0.154" (3.90mm) width.
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status.

The TC4432VOA713 qualifies as a direct substitute based on identical electrical and functional parameters. The primary distinction is packaging format: TC4432VOA is supplied in Tube packaging, while TC4432VOA713 is supplied in Tape & Reel (TR) format. Both share the same base product number (TC4432) and are manufactured by Microchip Technology with active product status.

Parameter Comparison

Engineering Selection Recommendations

Both TC4432VOA and TC4432VOA713 are active products from Microchip Technology with identical electrical and functional specifications. Selection between these parts is determined by packaging and supply chain requirements:

• TC4432VOA (Tube Packaging): Suitable for lower-volume applications, prototype development, and manual assembly workflows where tube packaging is preferred for handling and storage.
• TC4432VOA713 (Tape & Reel Packaging): Optimized for high-volume production environments requiring automated pick-and-place assembly. Tape & Reel format provides superior handling efficiency and reduced component damage risk in automated manufacturing.

Both parts maintain ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications. The TC4432VOA713 offers improved moisture sensitivity performance (MSL 1 vs. MSL 3), providing extended shelf life and reduced risk of moisture-induced failures during storage and transportation.

Frequently Asked Questions (FAQ)

Q: Are TC4432VOA and TC4432VOA713 electrically identical?

A: Yes. Both parts share identical electrical specifications, including supply voltage range (4.5V ~ 30V), output current (1.5A source and sink), logic voltage thresholds, rise/fall times, and operating temperature range. They are functionally interchangeable in circuit design.

Q: What is the primary difference between these two parts?

A: The primary difference is packaging format. TC4432VOA is supplied in Tube packaging, while TC4432VOA713 is supplied in Tape & Reel (TR) format. Additionally, TC4432VOA713 has improved moisture sensitivity (MSL 1 vs. MSL 3).

Q: Can I substitute TC4432VOA713 for TC4432VOA in my design?

A: Yes. TC4432VOA713 is a direct substitute for TC4432VOA. Both parts are mechanically compatible with the same 8-SOIC surface mount package and footprint. Substitution is valid for all electrical and functional requirements.

Q: Which packaging format should I choose for production?

A: Tape & Reel (TC4432VOA713) is recommended for automated assembly and high-volume production due to superior handling efficiency and reduced component damage. Tube packaging (TC4432VOA) is suitable for manual assembly, prototyping, and lower-volume applications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected. They meet identical regulatory requirements for industrial and commercial applications.

Q: What does MSL (Moisture Sensitivity Level) mean, and why does it differ?

A: MSL indicates the maximum time a component can be exposed to moisture at specified temperature and humidity conditions before soldering. TC4432VOA713 has MSL 1 (unlimited storage), providing extended shelf life compared to TC4432VOA with MSL 3 (168 hours). This difference reflects packaging format benefits in controlled storage environments.
