ISL6208IBZ

Gate Driver Overview

The ISL6208IBZ is a half-bridge gate driver IC manufactured by Renesas Electronics Corporation. It features two synchronous N-channel MOSFET drivers with non-inverting inputs. The device operates within a supply voltage range of 4.5V to 5.5V and supports logic levels with VIL of 0.5V and VIH of 2V. Peak output current capabilities are 2A source and 2A sink. Typical rise and fall times are 8ns each, with a maximum high-side bootstrap voltage of 33V. The component is available in an 8-QFN (3x3) package with exposed pad and functions across a junction temperature range of -40°C to 125°C.

Gate Driver Procurement Notes

Verify the specific suffix 'IBZ' against official Renesas documentation to confirm pinout and electrical specifications, as variations exist within the ISL6208 family. Confirm RoHS compliance status and moisture sensitivity level prior to PCB assembly planning. Check for active production status or obsolescence notices from the manufacturer before finalizing procurement plans.

Gate Driver Selection Notes

Select this component when a compact 8-pin solution is required for low-voltage synchronous applications. Ensure the design accommodates the 4.5V to 5.5V supply constraint and 33V bootstrap limit. Verify that the 2A peak current meets load requirements and that the QFN package thermal characteristics suit the application's power dissipation needs.

Gate Driver Part Context

The ISL6208 series belongs to Renesas' portfolio of power management integrated circuits, specifically designed for efficient gate driving in switching power supplies. This part represents a specialized variant optimized for small form-factor designs utilizing the 8-QFN package. It serves as a critical interface between low-voltage control logic and power stage MOSFETs.

Gate Driver Replacement Considerations

Consult official cross-reference lists for verified substitutes such as the ISL6208IRZ or ISL6208CBZ, ensuring package and specification compatibility.
