ISL6208CBZ

Gate Driver Overview

The ISL6208CBZ is a half-bridge gate driver IC manufactured by Renesas Electronics Corporation, designed for high-frequency dual MOSFET applications in core voltage regulation. It features two synchronous drivers with non-inverting inputs, supporting N-channel MOSFETs. The device operates within a supply voltage range of 4.5V to 5.5V and delivers peak output currents of 2A source and 2A sink. Typical rise and fall times are 8ns, with a maximum propagation delay of 25ns. It functions at high-side bootstrap voltages up to 33V and operates across a junction temperature range of -10°C to 125°C.

Gate Driver Feature Summary

• Provides synchronous half-bridge driving capability for high-side and low-side N-channel MOSFETs
• Features non-inverting input logic compatible with standard digital control signals
• Supports high-speed switching with typical 8ns rise and fall times for efficient power conversion
• Operates with a dedicated 4.5V to 5.5V supply rail independent of the high-side bootstrap voltage

Gate Driver Applications

• Core voltage regulation for advanced mobile microprocessors
• High-frequency DC/DC converter stages in server and storage equipment
• Synchronous rectification circuits in point-of-load (POL) power supplies

Gate Driver Procurement Notes

Verify component authenticity through authorized channels as the ISL6208CBZ has reached End-of-Life status. Confirm package integrity upon receipt, noting the 8-SOIC form factor. Check datasheet revisions for any specific handling or assembly changes documented in recent Product Change Notices. Ensure design compatibility with current thermal and electrical requirements before finalizing procurement plans.

Gate Driver Selection Notes

Select this component for designs requiring precise timing synchronization between high-side and low-side switches. The 2A peak drive current is suitable for medium-power MOSFETs in compact SOIC packages. Consider the -10°C to 125°C operating range for industrial or consumer electronics environments. Verify that the 33V bootstrap limit aligns with the target MOSFET gate drive requirements.

Gate Driver Part Context

The ISL6208CBZ belongs to the ISL6208 series of high-frequency dual MOSFET drivers developed by Renesas (formerly Intersil). It is functionally identical to the ISL6208B but differs in packaging. This series was engineered to provide complete single-stage solutions for core voltage regulators in mobile computing platforms, offering integrated protection and fast transient response capabilities.

Gate Driver Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, alternative sourcing should focus on verifying equivalent specifications from other manufacturers or consulting official Renesas recommendations for legacy replacements.
