ISL95808IRZ-T

Gate Driver Overview

The ISL95808IRZ-T is a half-bridge gate driver manufactured by Renesas Electronics Corporation, designed for synchronous MOSFET applications. It features two channels with non-inverting inputs and supports N-channel MOSFETs. The device operates within a supply voltage range of 4.5V to 5.5V and delivers peak output currents of 2A for both sourcing and sinking. It withstands a maximum high-side voltage of 33V using bootstrap configuration. Typical rise and fall times are 8ns each. The component functions within a junction temperature range of -40°C to 125°C and is housed in an 8-DFN (2x2) package with exposed pad.

Gate Driver Procurement Notes

Verify the specific suffix IRZ-T against official Renesas documentation to confirm the industrial temperature grade (-40°C to 125°C) and tape-and-reel packaging format. Cross-reference the exact part number with the manufacturer's current lifecycle status, as availability may be restricted or subject to discontinuation notices. Ensure compatibility with the required 33V bootstrap voltage rating and 8-DFN footprint during procurement validation.

Gate Driver Selection Notes

Select this component when a compact half-bridge solution with moderate 2A drive strength is required for low-voltage synchronous applications. The industrial temperature range suits environments exceeding standard commercial limits. Consider the 8ns switching speed and 33V isolation limit relative to the target circuit's voltage and frequency requirements. Validate that the 4.5V-5.5V supply range aligns with the system's available logic and driver power rails.

Gate Driver Part Context

The ISL95808 series belongs to Renesas' portfolio of specialized gate drivers intended for power management ICs. This specific model targets applications requiring isolated or floating half-bridge control. The IRZ-T variant denotes the industrial temperature grade and reel packaging. It complements other Renesas PMIC solutions by providing the necessary high-side and low-side switching signals for external MOSFETs in regulated power supplies.
