Typical Applications

IRS2184STRPBF is suitable for 6 applications: Switch-Mode Power Supplies (SMPS), Motor Drive Inverters (BLDC / PMSM), Electronic Ballasts for Lighting, Class D Audio Amplifiers, Uninterruptible Power Supplies (UPS), Solar Inverters (PV Microinverters).

⚡

Switch-Mode Power Supplies (SMPS)

The IRS2184STRPBF's 600V offset rating and 1.4A gate drive current make it ideally suited for half-bridge and full-bridge SMPS topologies operating from rectified 120V/240V AC mains. The integrated bootstrap architecture eliminates the need for an isolated high-side supply, reducing BOM cost. The 400ns built-in deadtime prevents shoot-through in the half-bridge switches. Place the driver within 2cm of the MOSFETs to minimize gate-loop inductance, and use a 1uF X7R bootstrap capacitor with a fast-recovery bootstrap diode rated for the full bus voltage.

🏭

Motor Drive Inverters (BLDC / PMSM)

For three-phase BLDC and PMSM motor drives, the IRS2184STRPBF can be paired in a half-bridge configuration per phase, driving the high-side and low-side IGBTs or MOSFETs of each inverter leg. Its 600V rating covers motor drives up to 400V DC bus (typical for 230V AC-derived systems). The 1.4A drive current handles gate charges typical of 10-20A continuous motor current MOSFETs. Combined with an external microcontroller or DSP for sinusoidal commutation, this enables compact, cost-effective motor control designs.

💡

Electronic Ballasts for Lighting

The IRS2184STRPBF is widely used in fluorescent and HID electronic ballasts, where it drives the resonant half-bridge inverter at frequencies typically between 25 kHz and 100 kHz. Its 600V rating handles the rectified mains bus, and the 1.4A drive current is sufficient for driving the gate capacitance of high-voltage MOSFETs in the ballast's resonant tank. The integrated deadtime of 400ns prevents cross-conduction that would otherwise waste power and stress the switches.

What is the IRS2184STRPBF and what is its primary function?

The IRS2184STRPBF is a 600V half-bridge gate driver IC from Infineon (formerly International Rectifier) housed in an 8-pin SOIC package. Its primary function is to drive the gates of high-voltage power MOSFETs or IGBTs in half-bridge and full-bridge topologies, translating low-current 3.3V logic signals into high-current 1.4A gate drive pulses. According to the Infineon datasheet, it uses proprietary HVIC and latch-immune CMOS technology with dependent high-side and low-side output channels.

What is the maximum voltage rating of the IRS2184STRPBF?

The IRS2184STRPBF has a maximum offset voltage rating of 600V, allowing it to operate in half-bridge configurations fed from rectified 120V/240V AC mains (up to approximately 400V DC bus). This makes it suitable for offline SMPS, motor drives, and lighting ballast applications. According to the Infineon datasheet, the high-side channel floats on the VS pin referenced to the switching node, with built-in level-shifting to support the full 600V rating.

What is the difference between IRS2184STRPBF and IRS21844STRPBF?

The IRS2184 and IRS21844 are two variants in the same Infineon driver family. The IRS2184 has a non-inverting input logic (IN high -> HO and LO high), while the IRS21844 features additional logic options. Both share identical 600V rating, 1.4A drive current, and the same 8-pin SOIC package, making them drop-in compatible for typical half-bridge applications. The non-inverting IRS2184 is the most common choice for standard half-bridge driving.

IRS2184STRPBF vs IRS2109STRPBF - which is better for half-bridge applications?

The IRS2184STRPBF and IRS2109STRPBF are both Infineon half-bridge gate drivers in 8-pin SOIC, but they target different voltage classes. The IRS2184 is rated for 600V offset and is designed for offline SMPS and motor drives, while the IRS2109 is rated for 600V as well but offers independent input logic (separate HIN and LIN inputs instead of a single shared IN). For simpler designs with a single PWM input, the IRS2184 is preferable. For deadtime-controlled independent channel drive, the IRS2109 is the better choice.

What is the best drop-in replacement for the IRS2184STRPBF?

The best drop-in replacement for the IRS2184STRPBF in the same 8-SOIC package is the IRS21844STRPBF (same Infineon family, identical pinout, 600V rating). For cross-brand alternatives with the same 8-SOIC footprint and pinout, the IR2104 from Infineon (legacy IR part) and UCC27714 from Texas Instruments are commonly cited, though these may require verification of input logic polarity. Always cross-check the datasheet pinout before substituting in production designs.

Can I use an IR2104 in place of the IRS2184STRPBF?

The IR2104 and IRS2184 share the same 8-SOIC package and 600V rating, but their input logic differs. The IR2104 has a single input with internal deadtime generation and shutdown control, while the IRS2184 has a non-inverting input. For designs where the IRS2184's input logic and timing match the IR2104's behavior in the target application, the IR2104 can serve as a drop-in replacement. However, always verify pin-by-pin compatibility using both datasheets before substitution, especially for the SD/shutdown pin behavior.

When should I choose the IRS2184STRPBF over a bootstrap-less gate driver?

Choose the IRS2184STRPBF when you need a cost-effective half-bridge driver with integrated bootstrap diode functionality and 600V high-side capability for offline SMPS, motor drives, or lighting ballasts. The integrated bootstrap architecture eliminates the need for an isolated high-side supply, reducing BOM cost and PCB area. For low-voltage (<100V) applications or where galvanic isolation is required for safety, a bootstrap-less isolated driver (e.g., gate drive transformer or digital isolator + driver) may be more appropriate.

Where can I download the IRS2184STRPBF datasheet PDF?

The official Infineon IRS2184STRPBF datasheet can be downloaded as a PDF from Infineon's product page at infineon.com/assets/row/public/documents/24/49/infineon-irs2184-datasheet-en.pdf.

According to the Infineon datasheet, the pins are: Pin 1 = VCC (logic supply), Pin 2 = IN (logic input), Pin 3 = COM (low-side return), Pin 4 = LO (low-side gate drive output), Pin 5 = VSS / NC depending on revision, Pin 6 = VS (high-side floating supply return), Pin 7 = HO (high-side gate drive output), Pin 8 = VB (high-side floating bootstrap supply). Always confirm with the latest datasheet revision before PCB layout.

What is the output drive current of the IRS2184STRPBF?

The IRS2184STRPBF delivers 1.4A typical output source and sink current at the HO and LO gate drive outputs. This drive strength is sufficient for switching power MOSFETs with total gate charge up to approximately 50-70nC at switching frequencies up to 100 kHz. For higher gate-charge IGBTs (e.g., 100nC+), a higher-current driver or external buffer stage may be required. The 1.4A specification enables sub-100ns typical rise/fall times into moderate gate capacitances.

Is the IRS2184STRPBF RoHS compliant?

Yes, the IRS2184STRPBF is RoHS compliant. The 'PbF' suffix in the part number explicitly indicates lead-free (Pb-free) terminal plating, and the part meets current EU RoHS directive substance restrictions.

Key Differentiators

Non-inverting single-input logic (vs IRS2109STRPBF)

Same-package family variant for design flexibility (vs IRS21844STRPBF)

Design Notes

The bootstrap capacitor (between VB and VS) must be sized to supply the high-side gate charge Qg for the worst-case switching frequency and maximum duty cycle. A common starting point is Cboot = 10x Qg / Vdrop, where Vdrop is the allowable droop on the bootstrap supply. For a 50nC gate charge at 100kHz with 95% duty cycle, a 1uF X7R ceramic capacitor with a low-ESR fast-recovery diode (e.g., UF4007 or Schottky) is typically adequate. Place the bootstrap capacitor as close to pins 7 (HO) and 8 (VB) as possible to minimize parasitic inductance.

Gate-loop inductance between the driver's output pins (HO, LO) and the MOSFET gates must be minimized to prevent dv/dt-induced ringing and false triggering. Place the driver within 1-2 cm of the power MOSFETs, use wide and short gate drive traces, and consider a gate resistor (10-47 ohm) to dampen oscillations. The COM pin (pin 3) should be connected directly to the source of the low-side MOSFET (or power ground) with a separate trace from the logic ground to avoid high-current transients coupling into the logic input.

Do not exceed the maximum VCC supply voltage of 20V, as this can damage the internal logic. The IN pin is not internally pulled - if left floating, the input state is undefined and may cause spurious switching. Always tie IN to a defined logic level (HIGH or LOW) through the controller or a pull-down resistor. Also, ensure the high-side VS pin does not see negative transients below -0.3V (relative to COM) caused by inductive parasitics during switching; add a clamping diode if necessary.
