HIP4081AIBT

Full Half-Bridge (H Bridge) Drivers Overview

The HIP4081AIBT is a high-frequency, medium-voltage full-bridge N-channel FET driver IC manufactured by Renesas (formerly Intersil). It operates with a supply voltage range of 9.5V to 15V and delivers a peak output current of 2.5A. The device supports switching frequencies up to 1MHz, featuring typical rise and fall times of 10ns when driving a 1000pF load at 50°C. It utilizes a 20-pin SOIC package and includes an on-chip charge pump and bootstrap upper bias supplies for independent drive of four N-channel FETs in half-bridge or full-bridge configurations.

Full Half-Bridge (H Bridge) Drivers Procurement Notes

Verify the specific suffix 'BT' against official Renesas documentation, as standard listings often cite 'IBZ'. Confirm RoHS compliance status and lead-free availability, as earlier versions may differ. Check for End-of-Life notices regarding the base HIP4081A series and validate the manufacturer's current production status for this exact part number before procurement.

Full Half-Bridge (H Bridge) Drivers Selection Notes

Select this component for applications requiring high-frequency operation up to 1MHz with precise dead-time control. Ensure the design accommodates the 9.5V to 15V supply range and utilizes the internal charge pump for high-side driving. Consider the thermal performance in free air at 50°C when designing for maximum frequency loads. Verify compatibility with the target logic voltage levels between 5V and 15V.

Full Half-Bridge (H Bridge) Drivers Part Context

The HIP4081A belongs to the Intersil/Renesas family of high-performance gate drivers designed for medium-voltage applications. It is engineered to replace older discrete solutions by integrating bootstrap and charge pump circuits into a single 20-pin package. This integration simplifies board layout and reduces component count for full-bridge topologies compared to separate half-bridge drivers.
