IR2184 Half-Bridge Gate Driver IC - Equivalent & Substitute Parts

Part Overview

The IR2184 is a half-bridge gate driver IC manufactured by Infineon Technologies, designed for driving IGBT and N-Channel MOSFET configurations in power management applications. The device operates with a supply voltage range of 10V to 20V and provides synchronized dual-channel gate driving with peak output currents of 1.9A (source) and 2.3A (sink).

The IR2184 is classified as obsolete, which necessitates identification of functionally equivalent substitute components for new designs and ongoing system support. Direct substitutes maintain identical electrical and mechanical specifications while offering improved compliance status and availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IR2184 is based on strict equivalence across all electrical and mechanical parameters. The primary substitute, IR2184PBF, maintains identical specifications for driven configuration, channel type, driver count, gate type compatibility, supply voltage range, logic voltage thresholds, peak output currents, input type, bootstrap voltage rating, switching times, operating temperature range, and physical package dimensions.

The substitution is valid because both parts share:

• Identical half-bridge synchronous dual-channel architecture
• Matching supply voltage specification (10V ~ 20V)
• Equivalent peak output current ratings (1.9A source, 2.3A sink)
• Same 600V bootstrap voltage capability
• Identical 8-DIP through-hole package footprint
• Matching thermal operating range (-40°C ~ 150°C)

Parameter Comparison

Engineering Selection Recommendations

The IR2184PBF serves as the direct functional equivalent to the IR2184. Both devices are electrically and mechanically identical across all specified parameters, enabling pin-for-pin replacement in existing circuit designs.
