ISL89411IPZ Equivalent & Substitute Parts

Part Overview

The ISL89411IPZ is a low-side gate driver IC manufactured by Renesas Electronics Corporation, designed for independent N-Channel and P-Channel MOSFET control in power management applications. This device operates with a supply voltage range of 4.5V to 18V and delivers 2A peak output current on both source and sink channels. The ISL89411IPZ is classified as obsolete, making equivalent substitute parts necessary for new designs and production continuity. Substitute parts must maintain compatibility with the 8-DIP package format and preserve the core functional characteristics of low-side gate driving with inverting input logic.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ISL89411IPZ is determined by the following mandatory parameters:

• Package Compatibility: All substitutes must use 8-DIP (0.300", 7.62mm) through-hole packaging
• Functional Configuration: Low-side gate driver with independent dual-channel architecture
• Gate Type: Support for N-Channel and P-Channel MOSFET control
• Input Logic: Inverting input type
• Supply Voltage Range: Minimum overlap with 4.5V ~ 18V specification
• Peak Output Current: Minimum 2A source and sink capability
• Mounting Type: Through-hole only

The three substitute parts identified—TC4423AVPA (Microchip Technology), UC2709N (Texas Instruments), and UC3709N (Texas Instruments)—satisfy all mandatory compatibility criteria. Each maintains the 8-DIP package format, dual independent low-side driver configuration, and inverting input logic required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

TC4423AVPA (Microchip Technology) is the primary substitute for the ISL89411IPZ. This part maintains identical supply voltage range (4.5V ~ 18V) and logic threshold specifications (0.8V, 2.4V). The TC4423AVPA exceeds the original output current specification with 4.5A peak capability and extends the operating temperature range to -40°C ~ 150°C. Product status is active with full ROHS3 and REACH compliance. The extended temperature range and higher output current provide enhanced performance margins for demanding applications.

UC2709N (Texas Instruments) serves as an alternative substitute with active product status and full compliance certifications. This part operates across an extended supply voltage range of 5V ~ 40V, providing broader application flexibility. However, the peak output current is reduced to 1.5A, which falls below the original 2A specification. The operating temperature range is -40°C ~ 85°C. This substitute is suitable for applications where the lower output current is acceptable and the extended supply voltage range is beneficial.

UC3709N (Texas Instruments) is functionally equivalent to UC2709N with identical electrical specifications but operates within a narrower temperature range of 0°C ~ 70°C. This part is appropriate for commercial-grade applications with standard temperature requirements. Peak output current remains at 1.5A with the same extended supply voltage range of 5V ~ 40V.

All three substitutes maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility with modern manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can TC4423AVPA directly replace ISL89411IPZ without circuit modifications?

A: Yes. TC4423AVPA maintains identical supply voltage range (4.5V ~ 18V), logic thresholds (0.8V, 2.4V), and 8-DIP package format. The higher output current (4.5A vs. 2A) and extended temperature range represent performance enhancements rather than incompatibilities. No circuit modifications are required.

Q: What is the key difference between TC4423AVPA and the UC27xx/UC37xx series?

A: TC4423AVPA matches the original supply voltage specification (4.5V ~ 18V), while UC2709N and UC3709N operate at 5V ~ 40V. Additionally, TC4423AVPA delivers 4.5A peak output current compared to 1.5A for the UC series. The UC series offers extended supply voltage flexibility but reduced output current capability.

Q: Are UC2709N and UC3709N interchangeable?

A: Both parts share identical electrical specifications and output current ratings
