Typical Applications
IRS2302STRPBF is suitable for 6 applications: BLDC / PMSM Motor Drive Inverter, Half-Bridge SMPS Primary Drive, Solar Micro-Inverter Power Stage, Uninterruptible Power Supply (UPS) Inverter, Induction Heating Inverter, Class D Audio Amplifier Output Stage.
BLDC / PMSM Motor Drive Inverter
The IRS2302STRPBF is well-suited to drive a single phase leg of a 3-phase BLDC or PMSM motor inverter because its 600 V high-side rating covers 220 V AC-line-rectified bus designs up to 380 V DC, and its 0.2 A source / 0.35 A sink drive currents switch typical 600 V MOSFETs at up to 50 kHz PWM. The matched propagation delays (220 ns typical) keep the high-side and low-side channels phase-accurate, which is critical for sinusoidal commutation. The integrated shutdown pin provides hardware-level fault propagation from DESAT or overcurrent comparators, disabling both gate outputs within microseconds. For full 3-phase integration, designers typically pair three IRS2302STRPBF channels or migrate to the IRS2334MTRPBF.
Recommended
Half-Bridge SMPS Primary Drive
In a half-bridge SMPS primary-side topology, the IRS2302STRPBF drives two primary MOSFETs at up to 600 V bus with symmetric timing. The built-in UVLO on both VCC and VBS prevents partial-turn-on switching that would otherwise dissipate excessive switching loss, and the dV/dt immunity of the floating high-side channel handles the hard-switching transients of the phase node. Bootstrap operation eliminates the need for an isolated gate-drive supply for the high side, reducing BOM cost. The 0.35 A sink current ensures fast turn-off, limiting shoot-through losses in 100-300 kHz LLC and hard-switched half-bridge converters up to 500 W.
Recommended
Solar Micro-Inverter Power Stage
The IRS2302STRPBF is appropriate for grid-tied solar micro-inverter power stages that require driving a half-bridge from a 380-400 V DC link. Its 600 V floating channel handles the maximum DC bus voltage with adequate derating, while the 0.2 A source / 0.35 A sink drive currents are sufficient for driving CoolMOS or IGBT power switches at the 20-100 kHz switching frequencies typical of residential micro-inverters. The shutdown pin enables fast anti-islanding protection by disconnecting the half-bridge within one PWM cycle on grid-fault detection. Combined with an MPPT controller and a PFC stage, the IRS2302STRPBF supports EN50549-compliant 230 V AC output from a single 600 V stage.
Recommended
Uninterruptible Power Supply (UPS) Inverter
In a line-interactive or on-line UPS, the IRS2302STRPBF drives the half-bridge inverter stage that converts 48 V or 192 V battery DC into 230 V AC mains. The 600 V offset rating handles 192 V battery-link designs, and the matched channel delays ensure clean 50/60 Hz sine synthesis with low harmonic distortion. Hardware shutdown via the SD pin provides emergency disconnect within microseconds, complementing the firmware-driven battery management system. Combined with an output LC filter and a feedback controller, the IRS2302STRPBF supports 500 VA to 2 kVA UPS designs for SOHO and small-server backup power.
Recommended
Induction Heating Inverter
The IRS2302STRPBF is well-suited to drive the resonant half-bridge in induction-heating cooktops and RF induction heaters. Its 600 V offset handles 220-380 V rectified mains, while the 0.35 A sink current provides fast turn-off that limits shoot-through losses in the 20-100 kHz resonant switching cycles. The matched propagation delays and built-in cross-conduction prevention simplify timing-critical zero-voltage switching (ZVS) designs. The shutdown pin enables hardware-level emergency stop, mandatory in appliance-grade induction cooking equipment.
Recommended
Class D Audio Amplifier Output Stage
In a half-bridge Class D audio amplifier, the IRS2302STRPBF drives the output MOSFETs that synthesize an audio-frequency PWM signal from the audio input. The matched 220 ns propagation delays minimize distortion by keeping high-side and low-side pulses phase-accurate, while the 0.35 A sink current enables fast switching transitions that limit dead-time distortion above the 20 kHz audio band. The 600 V rating supports high-power amplifier designs up to several kilowatts, while the built-in UVLO prevents audible clicks during power-up. For full H-bridge audio amplifiers, two IRS2302STRPBF channels are paired with an audio-modulation controller.

Key Differentiators
- Dedicated shutdown (SD) pin with hardware fault propagation (vs IR21531STRPBF)
- Asymmetric source/sink drive for MOSFET gate-charge asymmetry (vs IRS4428STRPBF)
- Integrated cross-conduction prevention with matched propagation delays (vs IR21064STRPBF)
Design Notes
Place the VCC bypass capacitor (typically 0.1 uF ceramic plus 10 uF tantalum or aluminum-polymer) as close as possible to pins 1 (VCC) and 5 (VSS) to keep the high di/dt return currents out of the logic-ground traces. Use a separate analog ground island tied to VSS at a single point to avoid digital-to-analog ground bounce on the SD input. The VBS-to-VS capacitor (0.1 uF to 1 uF low-ESR ceramic) must be placed within 5 mm of pins 6 (VS) and 8 (HO/VBS) to minimize switching ringing on the high-side supply rail.
Size the bootstrap capacitor to limit voltage droop during the high-side on-time. The droop is approximately Vdroop = Qg_total / CBOOT, where Qg_total is the high-side MOSFET gate charge. For a 50 nC gate charge and a target droop of less than 0.5 V (below the VBS UVLO threshold by at least 0.5 V), CBOOT must be at least 0.1 uF; for 100 nC gate charge use at least 0.22 uF. Add a local 0.1 uF ceramic in parallel to suppress high-frequency ringing. Choose a fast-recovery bootstrap diode with trr less than 100 ns and a low forward drop (Schottky preferred for VCC up to 15 V; ultrafast recovery for higher VCC).
Do not connect the SD pin to a slow analog signal without a small RC filter, as noise on SD can cause spurious shutdown events. If the application does not need shutdown, tie SD to VCC through a 10 kohm pull-up resistor. Avoid routing the phase node (VS) under the device or any logic-level traces, as the dV/dt of the phase node can inject noise into the high-side well. For the floating high-side supply, never exceed 600 V offset between VSS and VS; even brief over-voltage transients can permanently damage the HVIC junction isolation.
The IRS2302STRPBF in 8-SOIC has a thermal resistance theta_JA of approximately 150 C/W on a 1-oz 1-square-inch copper pad. With typical 0.2 A drive into 50 nC gate charge at 50 kHz, the IC dissipates approximately 0.5 mW per channel of gate-drive loss, which is negligible. However, if the SD pin is held low for extended periods under high ambient temperatures, the quiescent current may increase the IC temperature. For high-temperature applications (>100 C ambient), increase PCB copper area around the exposed VSS pad or use a small forced-air cooling path to maintain junction temperature below 125 C maximum rating.
