IRS2302SPBF Overview
What is a half-bridge gate driver? A half-bridge gate driver is an integrated circuit that translates low-voltage logic-level PWM signals from a microcontroller or DSP into the high-current, level-shifted gate-drive signals required to switch the high-side and low-side power transistors in a half-bridge topology. These drivers sit within the broader gate-driver IC family, which in turn belongs to power management semiconductors. They are essential building blocks in motor drives, switch-mode power supplies, and DC-AC inverters, where they provide logic-to-power isolation, level shifting, and timing/shoot-through protection between the controller and the switching power stage.
Key features of the IRS2302SPBF include a typical propagation delay of 220 ns (some sources quote 200 ns), matched high-side/low-side delay paths, built-in dead-time control logic, and under-voltage lockout (UVLO) protection for both the VCC and VS (high-side floating supply) rails. The HVIC and latch-immune CMOS process enables monolithic construction that is dV/dt immune and tolerant to negative transient voltages on the VS node, eliminating the need for external protection diodes on the bootstrap rail in most applications.
Architecturally, the IRS2302SPBF uses a bootstrap-capacitor technique for the high-side channel: a small external diode and capacitor generate a floating supply referenced to the switching node (VS), allowing the high-side output to swing with the half-bridge midpoint. This technique is widely used in sub-1 kW motor drive and SMPS designs because it requires only a single low-voltage supply rail. Compared with gate-drive transformers, the bootstrap approach is simpler and cheaper but limits the high-side on-time to the recharge period of the bootstrap capacitor.
Typical applications include three-phase and single-phase motor drives (variable-frequency drives, fan and pump controllers), uninterruptible power supplies (UPS), solar micro-inverters, induction-heating inverter stages, and half-bridge or push-pull switched-mode power converters. The 600 V floating channel makes it well-suited to 230 V and 380 V AC-line applications when paired with appropriately rated MOSFETs or 600 V-class IGBTs.
When designing with the IRS2302SPBF, choose the bootstrap capacitor to maintain VS above the UVLO threshold during the worst-case high-side on-time, and verify that the bootstrap diode reverse-voltage rating exceeds the maximum DC bus voltage. A small gate-source resistor (10-47 ohm) on each power switch is recommended to control ringing and EMI without excessively slowing switching edges. The logic inputs are CMOS-compatible, allowing direct connection to a 3.3 V or 5 V microcontroller without level-shifters.

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.

- 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.
