IR2184S

Gate Driver Overview

The IR2184S is a high-voltage, high-speed power MOSFET and IGBT driver IC from Infineon Technologies. It features a half-bridge topology with two independent output channels designed for floating operation up to 600V. The device supports bootstrap driving and includes undervoltage lockout (UVLO) for both the high-side and low-side supplies. It accepts 3.3V and 5V logic inputs and provides matched propagation delays to ensure reliable switching. The SOIC-14 package facilitates surface-mount integration.

Gate Driver Feature Summary

• High voltage capability supporting floating channel operation up to 600V
• Integrated undervoltage lockout protection for both high-side and low-side drivers
• Compatible with standard 3.3V and 5V CMOS/TTL logic input levels
• Matched propagation delay characteristics between output channels

Gate Driver Applications

• Motor control systems requiring isolated gate drive
• Power supply designs utilizing half-bridge topologies
• Inverter circuits for AC/DC conversion applications
• Industrial drives and servo motor controllers

Gate Driver Procurement Notes

Verify the specific suffix designation when ordering, as packaging formats such as tube or reel may vary by distributor. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing process. Ensure that the selected variant matches the required lead-free specifications for environmental regulations. Cross-reference the datasheet revision to confirm pinout compatibility with existing PCB layouts before finalizing procurement.

Gate Driver Selection Notes

Select this component for applications requiring robust isolation and high-speed switching capabilities in a compact surface-mount package. Consider the 600V rating when designing for medium-voltage power stages. Evaluate the thermal performance within the SOIC-14 enclosure against the expected duty cycle. Verify that the input logic voltage levels align with the control microcontroller or DSP outputs to ensure proper signal interfacing without additional level shifting.

Gate Driver Part Context

The IR2184S belongs to the IR2184 family of half-bridge drivers, which also includes variants like the IR2184 and IR21844. These devices share core functional architectures but differ in package types and pin configurations. The 'S' suffix specifically denotes the 8-lead SOIC package, distinguishing it from the PDIP versions. This family is widely used in industrial power electronics due to its reliability and ease of integration into existing control schemes.

Gate Driver Replacement Considerations

Direct substitutes include other 600V half-bridge drivers with similar pinouts and electrical characteristics. Check for equivalent source/sink current capabilities and propagation delay matching. Ensure that any replacement maintains the same UVLO thresholds and logic compatibility. Verify that the alternative component is available in an 8-lead SOIC package to fit the existing footprint.
