Typical Applications
IRS2302SPBF is suitable for 6 applications: Three-Phase Variable-Frequency Drive (VFD), Uninterruptible Power Supply (UPS) Inverter, Solar Micro-Inverter (Grid-Tie), BLDC Motor Driver for Robotics / Drones, Induction-Heating Cooktop Resonant Inverter, Half-Bridge Switched-Mode Power Supply (SMPS).
Three-Phase Variable-Frequency Drive (VFD)
The IRS2302SPBF drives the three half-bridge legs of a 230 V or 380 V three-phase inverter in industrial motor drives, with its 600 V floating channel, 200 mA source / 350 mA sink current, and dV/dt-immune HVIC. Two or three IRS2302SPBF units (one per phase) connect the MCU PWM outputs to the IGBT gates, with bootstrap capacitors generating the high-side floating rails. Compared with optocoupler-based drive schemes, the monolithic HVIC saves PCB area and eliminates component aging drift in fan/pump/HVAC motor controllers.
Recommended
Uninterruptible Power Supply (UPS) Inverter
In a UPS, the IRS2302SPBF drives the half-bridge stages that convert the battery DC bus to the 50/60 Hz AC output that feeds critical loads. Its 5 V-20 V VCC range operates directly from a 12 V or 24 V housekeeping rail, and the 600 V VS rating covers 120/230 V AC-line topologies without extra level-shifters. The 220 ns propagation delay and matched high/low paths keep PWM-to-output skew tight, minimizing dead-time-induced distortion and improving inverter efficiency above 95%.
Recommended
Solar Micro-Inverter (Grid-Tie)
The IRS2302SPBF drives the HERIC or H5 inverter topology in sub-1 kW solar micro-inverters, where its 600 V rating comfortably covers 400 V DC-link grids while the bootstrap high-side supply eliminates the bulk of gate-drive magnetics. With 350 mA sink current the part switches most 600 V MOSFETs at 50-100 kHz without additional buffer stages. Integrated UVLO on VCC and VBS protects the gate-driver logic from low-battery brownouts and DC-link droops during partial shading events.
Recommended
BLDC Motor Driver for Robotics / Drones
The IRS2302SPBF drives the three-phase inverter in BLDC motor controllers used in small robots, e-bikes, and drone ESCs where 24-48 V DC buses and 600 V-rated switches are common. Independent HIN/LIN inputs accept 3.3 V or 5 V PWM directly from a microcontroller or dedicated BLDC controller, and the SOIC-8N footprint suits space-constrained ESC PCBs. The 200 mA source current is sufficient for gate-drive of low-Qg MOSFETs at 25-50 kHz switching frequencies typical of hobby-grade motor controllers.
Recommended
Induction-Heating Cooktop Resonant Inverter
In a single-switch or half-bridge resonant induction-heating cooktop, the IRS2302SPBF drives the IGBTs that switch the LC tank at 20-50 kHz, delivering the 200 mA source current needed to charge and discharge typical 600 V/40 A IGBT gates. The negative-VS transient tolerance is critical here because the resonant tank can produce large dV/dt excursions exceeding 50 kV/us on the switching node. UVLO on both VCC and VBS prevents the IGBT from operating in the linear region during startup.
Recommended
Half-Bridge Switched-Mode Power Supply (SMPS)
In half-bridge and push-pull SMPS topologies (telecom rectifiers, server PSU primary stages, and industrial DC-DC converters), the IRS2302SPBF drives the two primary-side MOSFETs with 600 V headroom for 230 V AC-line applications. Its CMOS-compatible inputs accept 3.3 V or 5 V PWM from a current-mode controller such as the UCC25640x or NCP1337, and the matched propagation delays (220 ns typical) maintain near-50% duty cycle accuracy. Bootstrap-supplied high-side rail avoids bulky gate-drive transformers and simplifies isolation design.

Key Differentiators
- 600 V floating channel with negative VS transient tolerance (vs IR2104 (International Rectifier legacy))
- Wide 5 V-20 V VCC supply range (vs IRS2184SPBF (10 V-20 V supply only))
- Higher peak sink current (350 mA) (vs IR2011SPBF)
Design Notes
Bootstrap sizing: select the bootstrap capacitor (CBST) using the rule QG_total x n_periods < VCC - UVLO - VF_diode. For a typical 600 V/20 A IGBT with 100 nC total gate charge and 50 kHz switching, CBST >= 1 uF is recommended. A 1 uF to 4.7 uF X7R ceramic is typical. Use a fast-recovery diode (UF4007 or better) rated above the maximum DC-bus voltage - do not use 1N400x line-frequency diodes as they are too slow for bootstrap recovery.
Avoid shoot-through: the IRS2302SPBF does NOT include internal dead-time logic - it is the designer's responsibility to enforce a minimum dead-time between HIN and LIN transitions. Use the PWM controller's programmable dead-time or add an RC delay (~100 ns) on each input to prevent simultaneous high-side and low-side conduction. Shoot-through events can exceed 100 A peak current and destroy the half-bridge MOSFETs within microseconds.
Place the bootstrap diode and capacitor as close to pins 8 (VB) and 6 (VS) as possible, with traces short and wide (at least 0.5 mm / 20 mil). Keep the COM trace (pin 4) directly to the source of the low-side MOSFET - any inductance in this path develops a negative VS-relative swing that can exceed the absolute maximum rating. Place a 100 nF to 1 uF decoupling capacitor between VCC (pin 1) and COM (pin 4) within 5 mm of the IC.
