IR2184

Gate Driver Overview

The IR2184 is a high-voltage, high-speed half-bridge gate driver IC designed for driving power MOSFETs and IGBTs. It features a floating channel operational up to 600 V with bootstrap capability. The device supports a supply voltage range of 10 V to 20 V and includes undervoltage lockout (UVLO) thresholds at 8.2 V (Off) and 8.9 V (On). Output drive currents are specified as 1.9 A source and 2.3 A sink. Propagation delays are characterized at 680 ns for turn-on and 270 ns for turn-off. The component operates within a temperature range of -40 °C to +125 °C.

Gate Driver Feature Summary

• High voltage operation up to 600 V with tolerance for negative transient voltages
• Integrated bootstrap design for floating high-side channel operation
• Undervoltage lockout protection for both logic and power supply channels
• Compatible with 3.3 V and 5 V input logic standards

Gate Driver Applications

• Power MOSFET gate driving in industrial motor drives
• IGBT switching control in power conversion systems
• Automotive power electronics applications
• Synchronous rectifier circuits requiring dead-time prevention

Gate Driver Procurement Notes

Verify the specific package variant required for the design, as the IR2184 family includes PDIP-14, SOIC-8, and SOIC-14 options. Confirm that the selected part number suffix corresponds to the intended lead-free (PbF) status and tape-and-reel or tube packaging format. Ensure compatibility with the target PCB footprint before finalizing procurement orders.

Gate Driver Selection Notes

Select this component when a robust half-bridge driver with 600 V isolation is required for medium-power applications. The matched propagation delay characteristics support synchronous operation without external dead-time insertion. Consider the output current capabilities relative to the total gate charge of the connected power devices to ensure adequate switching speed.

Gate Driver Part Context

The IR2184 belongs to the IR218x series of high-voltage gate drivers from Infineon Technologies. It is engineered for cross-conduction prevention through independent logic side referenced outputs. The device integrates functional level-shift technology to isolate low-side logic inputs from high-side power outputs.

Gate Driver Replacement Considerations

Public confirmed substitute part numbers include IR21844, IR2184S, and IR21844S. These variants share identical electrical specifications but differ in physical package configurations such as SOIC-14 or SOIC-8.
