ISL6208CRZ-T

Gate Driver Overview

The ISL6208CRZ-T is a half-bridge gate driver IC manufactured by Renesas Electronics Corporation. It features two synchronous drivers designed for N-channel MOSFETs, housed in an 8-QFN (3x3) package with exposed pad. The device operates within a supply voltage range of 4.5V to 5.5V and supports logic input levels of 0.5V (VIL) and 2V (VIH). It delivers peak output currents of 2A for both sourcing and sinking. The maximum high-side bootstrap voltage is rated at 33V, with typical rise and fall times of 8ns each. The component is specified for operation across a junction temperature range of -10°C to 125°C.

Gate Driver Feature Summary

• Provides dual-channel synchronous half-bridge driving capability for efficient power switching applications.
• Features non-inverting input logic compatible with standard digital control interfaces.
• Utilizes a compact 8-QFN surface-mount package with an exposed thermal pad for improved heat dissipation.

Gate Driver Applications

• Synchronous rectification in DC/DC converter topologies
• Gate driving for low-voltage N-channel MOSFETs in power stages
• High-frequency switching circuits requiring fast transient response

Gate Driver Procurement Notes

Verify the specific suffix 'CRZ' against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status, as older Intersil variants may differ. Confirm that the 8-QFN footprint matches the PCB design, noting the exposed pad requirement for thermal management. Check for any recent Product Change Notifications (PCN) regarding material or packaging updates from Renesas.

Gate Driver Selection Notes

Select this component when a compact, dual-channel driver is needed for low-voltage synchronous applications. Ensure the system logic levels align with the 0.5V/2V input thresholds. Verify that the 33V bootstrap rating exceeds the maximum bus voltage requirements. Consider the 8ns switching speed for appropriate dead-time settings in the control loop to prevent shoot-through.

Gate Driver Part Context

The ISL6208 series originates from Intersil, now part of Renesas Electronics. This family of gate drivers is commonly used in point-of-load (POL) converters and other dense power supplies. The CRZ variant specifically denotes the tape-and-reel packaging format within the QFN package style, distinguishing it from tube-packaged versions like the IRZ.

Gate Driver Replacement Considerations

ISL6208CR-T is listed as a direct substitute, though both are marked as obsolete. Verify if ISL6208CRZ-T is available as a current production alternative from Renesas.
