Typical Applications
IRS2184SPBF is suitable for 6 applications: Brushless DC Motor Drive (BLDC/PMSM), Switch-Mode Power Supply Half-Bridge Converter, Electronic Ballast for HID and Fluorescent Lighting, Induction Heating Cooktop, Class-D Audio Amplifier, Solar Inverter and Power Conversion System.
Brushless DC Motor Drive (BLDC/PMSM)
The IRS2184SPBF is ideal for three-phase BLDC and PMSM motor drive inverter stages in the 100-500V bus class. Its 600V offset voltage handles 380V rectified industrial mains with comfortable margin for regenerative transients, while the 1.9A source / 2.3A sink peak current drives sub-50A MOSFETs in 30-100ns switching transitions, limiting switching losses to 1-3% of total inverter dissipation. In a typical three-phase inverter, three IRS2184SPBF ICs each drive one half-bridge leg (high-side N-MOSFET and low-side N-MOSFET), with the HIN/LIN inputs fed from a microcontroller's PWM module. The 3.3V logic compatibility allows direct connection to STM32, ESP32, or dsPIC PWM outputs without external level shifters, reducing BOM cost and PCB area.
Recommended
Switch-Mode Power Supply Half-Bridge Converter
In isolated half-bridge and full-bridge SMPS topologies (50-500W telecom and industrial power supplies), the IRS2184SPBF provides primary-side gate drive for the two primary MOSFETs or IGBTs forming the half-bridge leg. The 600V rating supports 380-400V DC bus voltages from rectified 230V AC mains with substantial margin. Its matched propagation delay between high-side and low-side channels prevents duty-cycle distortion that would otherwise cause DC bias in the transformer, while the built-in UVLO on VCC and VBS protects against partial-bootstrap-charge startup transients. The IRS2184SPBF's 3.3V logic input allows direct control from digital PFC + LLC controller ICs such as the Infineon ICE3 family.
Recommended
Electronic Ballast for HID and Fluorescent Lighting
The IRS2184SPBF is widely deployed in electronic ballasts for fluorescent tubes, high-intensity discharge (HID) lamps, and UV-C germicidal lamps, where it drives the resonant half-bridge LC tank at 30-100 kHz. Its 600V offset voltage easily handles the rectified 220-240V AC mains bus, and the 1.9A/2.3A peak current drives the gate capacitance of high-voltage MOSFETs without excessive rise/fall time. The matched propagation delay ensures balanced duty cycle to the resonant tank, preventing DC current component that would saturate the lamp transformer. The 8-SOIC package enables compact ballast designs that fit inside CFL and T5 lamp bases.
Recommended
Induction Heating Cooktop
In residential induction cooktops (1.5-3.5 kW), the IRS2184SPBF drives the resonant half-bridge or full-bridge that excites the induction coil at 20-50 kHz. Its 600V rating handles the rectified 220V mains DC bus, and the 1.9A source / 2.3A sink current drives high-voltage IGBTs such as the Infineon IHW30N160R5 family with switching times below 200 ns, reducing switching losses by 30-50% compared to smaller drivers. The matched high-side / low-side delay is critical here because any duty-cycle imbalance injects DC into the resonant tank, which can saturate the induction coil and cause catastrophic failure.
Recommended
Class-D Audio Amplifier
The IRS2184SPBF can be used in mid-power Class-D audio amplifiers (50-300W per channel) where it drives the half-bridge output stage switching at 250-500 kHz. The 600V rating supports higher bus voltages for greater audio dynamic range, and the matched propagation delay ensures that both halves of the H-bridge output switch with minimal timing skew, preserving THD below 0.1%. The 3.3V logic input allows direct modulation from common Class-D controller ICs. For sub-100W applications, the lower-current IRS2109STRPBF may be sufficient, but the IRS2184SPBF's higher drive current reduces crossover distortion at high modulation depths.
Recommended
Solar Inverter and Power Conversion System
In photovoltaic string inverters and small grid-tie inverters (1-5 kW), the IRS2184SPBF drives the half-bridge leg in the DC-DC boost stage that elevates the panel voltage to the DC link level. Its 600V rating handles 600V DC link voltages with margin, and the 1.9A/2.3A drive current suits sub-30A MOSFETs typical in residential PV inverters. The UVLO protection on VCC and VBS ensures defined startup and shutdown behavior when the DC link is charging, while the 3.3V logic compatibility allows direct PWM control from TI C2000 or Microchip dsPIC controllers used in MPPT algorithms.

Design Notes
Bootstrap capacitor sizing: For the IRS2184SPBF, choose CBOOT such that the voltage droop during the maximum high-side on-time is less than 100 mV. The governing equation is V_droop = Q_gate / C_BOOT, where Q_gate is the total gate charge of the high-side MOSFET transferred each switching cycle. For a 50 nC Qg MOSFET at 20 kHz switching, Q_gate_total β 1 uC per cycle; with a 1 uF CBOOT, V_droop = 1 V. A 0.47-1 uF ceramic X7R is typical for sub-100 kHz operation. Estimated: based on typical Qg = 50 nC, fsw = 20 kHz. Use a low-ESR ceramic such as Murata GRM21BR71C475KA73L. The bootstrap diode must be a fast-recovery type (trr < 100 ns) such as the UF4007 or an MMBD914.
PCB layout for the IRS2184SPBF must keep the VCC bypass capacitor (0.1 uF ceramic + 10 uF tantalum or aluminum-polymer) within 5 mm of pins 1 and 4, with the ground return path directly to pin 4 (not through a ground plane via chain). The bootstrap capacitor must be placed directly between pins 8 (VB) and 6 (VS) with the shortest possible trace length to minimize the high-current loop area. The high-side gate drive loop (HO -> gate -> source -> VS) should have an area below 1 cm^2 to limit parasitic inductance; otherwise, voltage ringing can exceed the IRS2184SPBF's absolute maximum VBS rating of 600 V during fast switching transitions.
Common pitfalls when using the IRS2184SPBF: (1) Failing to refresh the bootstrap capacitor when the low-side is held on for extended periods (100% duty cycle on high-side), causing VBS to drop below UVLO threshold and latch-off the high-side output. (2) Driving IN with a signal that exceeds VCC + 0.3 V or falls below GND - 0.3 V, which can cause latch-up. (3) Connecting the bootstrap diode anode to VCC instead of a separate 12-15 V rail, which prevents proper high-side UVLO behavior. (4) Omitting gate-source resistors on the power MOSFETs, leading to parasitic oscillation in the 50-200 MHz range due to gate-source capacitance resonance with the driver's output inductance.
The 8-SOIC IRS2184SPBF has a thermal resistance theta_JA of approximately 150 C/W (estimated: based on standard SOIC-8 JEDEC EIA/JESD51 1-oz 2-layer board). At 25 C ambient, this allows up to ~830 mW dissipation before hitting the 150 C junction limit. The dominant power dissipation is typically CVCC * fsw * Q_gate for the high-side driver. For example, with VCC = 15 V, fsw = 100 kHz, Qg = 50 nC, P_diss β 75 mW (one output switching). Below 500 kHz switching frequency, no heatsink is required, but adequate PCB copper pour connected to the ground pin is mandatory.
