ISL6596IBZ-T

Gate Driver Overview

The ISL6596IBZ-T is a half-bridge gate driver IC manufactured by Renesas Electronics Corporation. It features non-inverting inputs and is designed for synchronous MOSFET applications. The device operates within a supply voltage range of 4.5V to 5.5V and supports a maximum high-side bootstrap voltage of 36V. It provides peak output currents of 4A for sourcing and sinking. Typical rise and fall times are 8ns each. The component is housed in a 10-DFN (3x3) package with an exposed pad, suitable for surface mount installation. It functions as a two-channel driver.

Gate Driver Procurement Notes

Verify the specific suffix IBZ-T against official Renesas documentation to confirm tape-and-reel packaging and industrial temperature grade specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to assembly. Check for obsolescence notices or product change notifications that may affect long-term availability or manufacturing site changes.

Gate Driver Selection Notes

Select this component when a compact half-bridge driver with fast switching speeds is required for synchronous rectification. Ensure the control logic voltage aligns with the 4.5V to 5.5V supply range. Verify that the PCB layout accommodates the 10-DFN package dimensions and thermal pad requirements for adequate heat dissipation during operation.
