ICL7667CBAZA-T Gate Driver IC Equivalent & Substitute Parts

Part Overview

The ICL7667CBAZA-T is an inverting gate driver IC manufactured by Renesas Electronics Corporation, designed for independent dual-channel N-Channel MOSFET gate driving applications. This Surface Mount device operates within a 4.5V to 15V supply voltage range and is packaged in an 8-SOIC form factor. The part is currently Active in product status and ROHS3 compliant with unlimited moisture sensitivity rating.

Substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, packaging format changes, or extended operating temperature ranges while maintaining functional compatibility within the specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ICL7667CBAZA-T are qualified based on the following criteria:

Electrical Compatibility Parameters:

• Dual independent gate driver channels
• N-Channel MOSFET gate drive capability
• Inverting input logic configuration
• Supply voltage range overlap (minimum 4.5V, maximum ≥15V)
• Logic threshold voltage compatibility (VIL ≤0.8V, VIH ≥2V)
• Switching speed compatibility (rise/fall times ≤20ns typical)

Mechanical Compatibility Parameters:

• 8-SOIC package form factor (0.154", 3.90mm width)
• Surface Mount mounting type
• MSL 1 rating (unlimited moisture sensitivity)

Compliance Parameters:

• ROHS3 compliance
• Active product status
• EAR99 export classification

Substitutes are grouped into two categories: direct functional equivalents (ICL7667CBA+, ICL7667EBA+) and compatible alternatives with extended operating temperature ranges (MIC4426YM, MIC4426YM-TR).

Parameter Comparison

Engineering Selection Recommendations

ICL7667CBA+ and ICL7667EBA+ (Analog Devices Inc./Maxim Integrated): These parts share the ICL7667 base product number and maintain identical electrical characteristics to the ICL7667CBAZA-T, including supply voltage range extension to 17V and extended operating temperature range to 150°C (TJ). Both are ROHS3 compliant and Active in product status. Selection between these variants depends on packaging format availability (Tube packaging for both).

MIC4426YM and MIC4426YM-TR (Microchip Technology): These gate driver ICs from Microchip Technology provide extended supply voltage range (4.5V ~ 18V) and wider operating temperature range (-40°C ~ 150°C TJ). The MIC4426YM-TR variant is supplied in Cut Tape & Digi-Reel packaging, matching the original ICL7667CBAZA-T packaging format. Both MIC4426 variants support dual gate drive channels with independent configuration and are ROHS3 compliant with Active product status. The fall time specification extends to 29ns typical, within acceptable switching speed parameters for gate driver applications.

All substitute parts maintain 8-SOIC package compatibility, MSL 1 rating, and EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can ICL7667CBA+ or ICL7667EBA+ be used as direct replacements for ICL7667CBAZA-T?

A: Yes. Both parts maintain identical electrical specifications for gate drive functionality, including dual independent channels, N-Channel MOSFET gate drive, inverting logic input, and matching rise/fall times. The extended supply voltage range (4.5V ~ 17V) and operating temperature range (0°C ~ 150°C TJ) provide additional design margin. Package form factor and MSL rating are identical.

Q: What are the key differences between ICL7667 variants and MIC4426 gate drivers?

A: The primary differences are: (1) MIC4426 supports both N-Channel and P-Channel MOSFET gate drive, while ICL7667 supports N-Channel only; (2) MIC4426 provides extended operating temperature range (-40°C ~ 150°C TJ) compared to ICL7667 (0°C ~ 150°C TJ); (3) MIC4426 fall time is 29ns typical versus 20ns for ICL7667; (4) MIC4426 supply voltage extends to 18V versus 17V for ICL7667. All maintain identical 8-SOIC packaging and dual independent channel configuration.

Q: Does packaging format affect substitution compatibility?

A: Packaging format does not affect electrical or functional compatibility. ICL7667CBAZA-T is supplied in Cut Tape & Digi-Reel format. ICL7667CBA+ and ICL7667EBA+ are supplied in Tube format. MIC4426YM is supplied in Tube format, while MIC4426YM-TR is supplied in Cut Tape & Digi-Reel format, matching the original part's packaging. Selection depends on procurement and assembly process requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (ICL7667CBA+, ICL7667EBA+, MIC4426YM, MIC4426YM-TR) are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the compliance profile of ICL7667CBAZA-T.

Q: What is the significance of the extended operating temperature range in MIC4426 variants?

A: The MIC4426YM and MIC4426YM-TR extend the operating temperature range to -40°C ~ 150°C (TJ), compared to 0°C ~ 70°C (TA) for ICL7667CBAZA-T. This extended range accommodates applications requiring operation in wider ambient or junction temperature environments. Selection depends on specific application thermal requirements.
