M81716FP Power Switch/Driver IC - Equivalent & Substitute Parts

Part Overview

The M81716FP is a Power Switch/Driver IC manufactured by Powerex Inc., designed for general-purpose power management applications with a 1:1 input-to-output ratio and 2-output configuration. This component operates across a load voltage range of 4.5V to 17V and features an on/off interface with 7Ω typical on-resistance in an 8-SOP surface mount package. The M81716FP is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the M81716FP is determined by the following critical parameters:

• Number of Drivers/Outputs: Must be 2 independent channels
• Input Type: Must be inverting configuration
• Package Type: Must be 8-SOIC surface mount
• Voltage Supply Range: Must accommodate the 4.5V minimum and preferably extend to or beyond 17V load voltage
• Operating Temperature Range: Must support -40°C to 125°C or equivalent industrial range
• Gate Type Compatibility: Must support N-Channel and/or P-Channel MOSFET driving
• RoHS Compliance: Must meet RoHS3 or equivalent environmental standards

The identified substitute parts meet these core electrical and mechanical criteria, enabling direct functional replacement in applications requiring power switching and driver functionality.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility)

The EL7212CSZ and EL7212CSZ-T7 (Renesas Electronics) provide the closest functional alignment to the M81716FP. Both parts maintain the full -40°C to 125°C operating temperature range, support N-Channel and P-Channel MOSFET gate driving, and feature 2A peak output current capability. The voltage supply range of 4.5V to 15V covers the lower operating envelope of the M81716FP. These parts are available in active production status with ROHS3 compliance and MSL 3 rating.

The ISL89411IBZ (Renesas Electronics) extends the upper voltage supply limit to 18V, providing additional headroom beyond the M81716FP specification. This part maintains the full industrial temperature range (-40°C to 125°C), supports dual gate type configurations, and is actively produced with ROHS3 compliance.

Secondary Substitutes (Conditional Compatibility)

The ICL7667CBAZA and ICL7667CBAZA-T (Renesas Electronics) are gate driver ICs with 2 independent channels and inverting input configuration. These parts operate within the 4.5V to 15V supply range and feature ROHS3 compliance. However, the operating temperature range is limited to 0°C to 70°C, which does not extend to the full -40°C industrial minimum of the M81716FP. These parts are suitable for applications operating within the 0°C to 70°C envelope only.

All substitute parts are manufactured by Renesas Electronics Corporation and maintain active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the EL7212CSZ directly replace the M81716FP in all applications?

A: The EL7212CSZ meets the core electrical and mechanical substitution criteria: 2 independent inverting drivers, 8-SOIC package, -40°C to 125°C operating range, and N-Channel/P-Channel MOSFET support. The voltage supply range of 4.5V to 15V covers the M81716FP's lower operating envelope. Applications operating within these parameters can use the EL7212CSZ as a direct substitute. Designs requiring operation above 15V supply voltage should use the ISL89411IBZ instead.

Q: What is the difference between EL7212CSZ and EL7212CSZ-T7?

A: Both parts are functionally identical EL7212 gate driver ICs with the same electrical specifications. The difference is in packaging format: EL7212CSZ is supplied in Tube packaging, while EL7212CSZ-T7 is supplied in Cut Tape (CT) & Digi-Reel® format. Selection depends on procurement and assembly requirements.

Q: Why do the ICL7667CBAZA parts have a narrower operating temperature range?

A: The ICL7667CBAZA and ICL7667CBAZA-T are specified for 0°C to 70°C operation, which does not include the full -40°C to 125°C industrial range of the M81716FP. These parts are suitable only for applications operating within the 0°C to 70°C temperature envelope. For full industrial temperature range compatibility, use the EL7212CSZ, EL7212CSZ-T7, or ISL89411IBZ instead.

Q: Are all substitute parts RoHS compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, meeting current environmental and regulatory requirements. The M81716FP carries RoHS Compliant status. All substitutes maintain or exceed this compliance level.

Q: What is the significance of the 8-SOIC package width difference?

A: The M81716FP is packaged in 8-SOIC (0.173", 4.40mm Width), while all substitute parts use 8-SOIC (0.154", 3.90mm Width). Both are standard 8-SOIC configurations with identical pin counts and spacing. The width difference reflects manufacturing variations between suppliers. PCB footprints designed for standard 8-SOIC packages will accommodate both variants without modification.

Q: Which substitute part offers the highest voltage supply capability?

A: The ISL89411IBZ supports a voltage supply range of 4.5V to 18V, extending 3V above the M81716FP's 17V maximum load voltage specification. This part is recommended for applications requiring operation at or near the upper voltage limits.
