ISL89411IBZ

Gate Driver Overview

The ISL89411IBZ is a high-speed, dual-channel power MOSFET driver manufactured by Renesas Electronics. It operates within a supply voltage range of 4.5 V to 18 V and delivers a peak output current of 2 A. The device features an inverting configuration with independent channels for N-Channel and P-Channel MOSFETs. Key timing parameters include a rise time of 10 ns and a fall time of 13 ns. It is housed in an 8-lead SOIC package.

Gate Driver Feature Summary

• Dual independent channel design for driving both N-Channel and P-Channel MOSFETs
• High-speed switching performance with 10 ns rise time and 13 ns fall time
• Inverting logic configuration for simplified control interface
• Robust 2 A peak output current capability for efficient gate drive

Gate Driver Applications

• Low-side power switching applications
• DC-DC converter circuits
• Motor control systems requiring fast MOSFET switching

Gate Driver Procurement Notes

Verify component status as the ISL89411IBZ is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing PCB footprints and validate that alternative sources provide genuine parts with intact specifications. Check for any specific handling requirements due to age.

Gate Driver Selection Notes

Select this component for designs requiring dual low-side gate drivers with high speed and moderate current drive. The inverting configuration suits applications where signal inversion is acceptable or required. Consider the SOIC-8 package constraints and verify that the 4.5 V to 18 V supply range aligns with the system's power architecture. Evaluate thermal performance under continuous operation.

Gate Driver Part Context

This part belongs to the ISL89411 series of high-speed dual MOSFET drivers from Renesas (formerly Intersil). It is designed for general-purpose power management applications. The device integrates two identical driver channels on a single chip, reducing board space compared to discrete solutions. It is part of the broader portfolio of gate drivers optimized for efficiency and switching speed.

Gate Driver Replacement Considerations

Check for direct pin-to-pin replacements such as the ISL89411IBZ-T13 variant if tape-and-reel packaging is needed. Verify functional equivalence with other dual low-side drivers from Renesas or competitors like Infineon or Texas Instruments. Ensure replacement parts match the 2 A current rating and 10 ns/13 ns timing characteristics.
