IR2085STR

Gate Driver Overview

The IR2085STR is a half-bridge gate driver IC manufactured by Infineon Technologies, housed in an 8-SOIC package. It features RC input circuitry and supports independent channel operation with two drivers. The device provides peak output currents of 1A for both sourcing and sinking. It operates within a supply voltage range of 10V to 15V and withstands high-side voltages up to 100V using bootstrap configuration. Typical rise and fall times are 40ns and 20ns, respectively. The component is rated for junction temperatures between -40°C and 150°C.

Gate Driver Feature Summary

• Integrates a self-oscillating half-bridge driver with programmable switching frequency capabilities up to 500kHz.
• Features a floating high-side channel design suitable for bootstrap operation at voltages up to 100Vdc.
• Includes adjustable dead-time control ranging from 50ns to 200ns for optimized switching performance.

Gate Driver Applications

• Half-bridge DC-DC converters in distributed power systems
• Motor drive applications requiring isolated gate driving
• Inverter circuits utilizing low-charge MOSFETs

Gate Driver Procurement Notes

Verify the specific suffix and RoHS compliance status, as datasheets indicate non-RoHS variants exist. Confirm availability as the part may be subject to end-of-life restrictions or obsolescence notices. Ensure the ordering code matches the required lead-free or standard packaging specifications for your assembly process.

Gate Driver Selection Notes

Select this component when a compact SOIC-8 solution is needed for half-bridge topologies. It is suitable for designs requiring integrated oscillation and simple RC timing control. Consider the AUIR2085STR variant if automotive qualification under AEC-Q100 standards is mandatory for the application environment.

Gate Driver Part Context

This part belongs to the IR2085 family of half-bridge drivers. It combines primary-side control logic with power stage driving capabilities. The STR suffix denotes tape-and-reel packaging. It serves as a cost-effective alternative to discrete driver solutions, reducing component count and board space in power conversion architectures.

Gate Driver Replacement Considerations

The AUIR2085STR is a qualified automotive-grade equivalent within the same product family. Verify pin compatibility and thermal characteristics before substitution. Check for updated datasheet revisions that may alter electrical parameters or packaging options.
