IRS2184STRPBF Overview
A gate driver is a power-management IC that sits between a low-power controller (microcontroller, DSP, or logic output) and a high-power switching device (MOSFET or IGBT). It translates low-current logic-level signals into high-current gate drive signals capable of rapidly charging and discharging the gate capacitance of power switches. Gate drivers belong to the broader hierarchy of power management ICs and are essential in switch-mode power supplies (SMPS), motor drives, and DC-DC converters where the control circuit must remain electrically isolated from the high-voltage switching node.
Key features include a 600V maximum offset voltage rating allowing operation in 120V/240V AC-derived bus systems, 1.4A typical source/sink output drive current for fast switching transitions, and 3.3V logic-compatible inputs accepting standard CMOS or LSTTL outputs. The IRS2184 also integrates built-in deadtime (typically 400ns) to prevent shoot-through in half-bridge configurations. The 8-pin SOIC package is industry-standard and supports surface-mount assembly.
The IRS2184 uses a level-shifting circuit on the high-side channel that references the floating supply to the switching node (VS pin), enabling bootstrap operation from a single low-voltage supply. The low-side channel is referenced to ground (COM pin). This architecture eliminates the need for an isolated gate drive supply on the high side, reducing BOM cost and PCB area.
Typical applications include switch-mode power supplies (SMPS), uninterruptible power supplies (UPS), motor control inverters for small BLDC and PMSM motors, electronic ballasts for lighting, Class D audio amplifiers, and any half-bridge or full-bridge topology driving MOSFETs or IGBTs up to 600V bus voltage. The IRS2184 is specifically the non-inverting variant of the IRS2184 family (input high = HO high, LO high).
When designing with this driver, ensure the bootstrap capacitor is sized to supply the high-side gate charge for the worst-case switching frequency and duty cycle. A 100nF to 1uF ceramic capacitor with a low-ESR bootstrap diode is recommended. Place the driver as close as possible to the MOSFETs to minimize gate-loop inductance and prevent dv/dt-induced ringing.

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.
Recommended
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.
Recommended
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.
Recommended
Class D Audio Amplifiers
Although not a dedicated audio driver, the IRS2184STRPBF can drive Class D audio amplifier output stages at switching frequencies of 250 kHz to 1 MHz, with appropriate low-pass output filtering. The 600V rating supports high-power professional audio systems fed from 120V/240V mains. The 1.4A drive current and 400ns deadtime provide clean switching transitions critical for low THD+N audio reproduction. Note: dedicated audio-grade drivers (e.g., IRS2453D) may offer better audio-optimized performance for demanding applications.
Recommended
Uninterruptible Power Supplies (UPS)
In UPS systems, the IRS2184STRPBF drives the half-bridge stages of the inverter section that converts DC battery voltage back to AC mains voltage during power outages. The 600V rating supports 230V AC output via the inverter's high-side switches. The driver's 3.3V logic compatibility allows direct connection to UPS control DSPs or microcontrollers. Combined with an isolated DC-DC front-end, this enables a complete UPS power conversion stage in a compact surface-mount design.
Recommended
Solar Inverters (PV Microinverters)
The IRS2184STRPBF is suitable for solar microinverter and string inverter applications, where it drives the DC-DC and DC-AC conversion stages. Its 600V rating handles the boosted PV bus voltage (typically 400V), and the integrated bootstrap architecture simplifies the high-side drive. For higher-efficiency designs, consider pairing with Infineon's CoolMOS MOSFETs. The driver's -40C to +125C operating range supports outdoor PV installations with appropriate thermal management.

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.
