ISL78424AVEZ-T

Gate Driver Overview

The ISL78424AVEZ-T is an Automotive Grade AEC-Q100 Grade 1 high-voltage half-bridge NMOS FET driver designed for driving gates in up to 70V topologies. It features a single tri-level PWM input compatible with Renesas multiphase controllers, such as the ISL78225 and ISL78226. The device provides 3A sourcing and 4A sinking peak gate drive current with a maximum bootstrap supply voltage of 100V and a maximum phase voltage of 86V. It operates within a supply voltage range of 8V to 18V and supports an ambient temperature range from -40°C to +140°C.

Gate Driver Feature Summary

• Patented gate-sensed adaptive dead time control minimizes switching losses while providing shoot-through protection
• Unique tri-level PWM input enables direct integration with specific Renesas multiphase controllers
• Independent sourcing and sinking pins at driver outputs allow optimized gate drive performance

Gate Driver Applications

• High-frequency half-bridge power stage driving
• Automotive power electronics systems
• Multiphase controller interfacing

Gate Driver Procurement Notes

Verify the component matches the exact suffix AVEZ-T for HTSSOP-14 packaging. Confirm AEC-Q100 Grade 1 qualification status for automotive compliance. Ensure the design accommodates the 100V bootstrap limit and 86V phase voltage constraints. Check moisture sensitivity level requirements during storage and handling procedures.

Gate Driver Selection Notes

Select this model when independent source/sink pins are required for each gate driver channel. Choose over the ISL78444 if separate output pins are preferred over combined sourcing/sinking outputs. This part is suitable for designs requiring compatibility with Renesas tri-level PWM signals rather than standard logic inputs.

Gate Driver Part Context

This component belongs to the ISL784x4 family of half-bridge drivers, which also includes the ISL78434 and ISL78444. While the ISL78434 offers dual independent inputs, the ISL78424 utilizes a single tri-level PWM input. All variants share similar electrical characteristics, including peak drive currents and package options.

Gate Driver Replacement Considerations

The ISL78444 is pin-compatible with the ISL78420 but differs in output configuration. Direct substitutes within the same family include the ISL78434 for dual-input applications or the ISL78444 for combined output configurations.
