Product details
Overview
IR2233 from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with six independent gate drive channels (three high-side and three low-side), rated for up to 1200V offset voltage, ±200 mA / +420 mA output current, 750/700 ns typical turn-on/turn-off propagation delay, and 250 ns typical deadtime. It integrates an analog current-sense amplifier and over-current shutdown for motor inverter applications.
For engineers reviewing the IR2233 datasheet, IR2233 pinout, IR2233 application, or IR2233 equivalent, key selection criteria include its 1200V floating channel capability, matched propagation delays across all six drivers, 2.5V logic compatibility, integrated current sensing via CA+/CA−/CAO, and fault-clear functionality via FLT-CLR.
Technical Context
The IR2233 employs proprietary HVIC (High-Voltage IC) technology enabling monolithic integration of level-shifted high-side drivers tolerant to −5 V to +1200 V dV/dt transients. Its floating channels support bootstrap-gated N-channel MOSFETs or IGBTs in 3-phase inverter legs.
All three half-bridge pairs feature matched propagation delays (750/700 ns typ.), programmable deadtime (250 ns typ.), and independent undervoltage lockout on both VCC and VBx supplies. The integrated op-amp provides real-time analog current feedback with 5–10 V/µs slew rate and 50–70 dB CMRR/PSRR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET max | 1200 V - supports high-voltage motor drives up to industrial 690 VAC line-to-line systems with margin. |
| IO+ / IO− | 200 mA / 420 mA - sufficient peak current to rapidly charge/discharge gate capacitance of 1–2 kW IGBTs or MOSFETs. |
| ton / toff (typ.) | 750 / 700 ns - enables PWM operation up to ~500 kHz with minimal timing skew across phases. |
| Deadtime (typ.) | 250 ns - prevents shoot-through in 3-phase inverters without external timing circuitry. |
| VOUT range | 12–20 V - configurable gate drive voltage for optimal switching loss vs. robustness trade-off in Si/SiC power stages. |
| Logic threshold | 2.5 V compatible - interfaces directly with microcontrollers, FPGAs, and isolated digital isolators without level-shifting. |
| Current sense amp | CA+/CA−/CAO with 30 mV offset, 4 nA bias - enables accurate shunt-based phase current measurement at ≤1% error. |
Pinout & Package
IR2233 is available in 28-lead SOIC (wide body), 28-lead PDIP, and 44-lead PLCC (12 leads omitted) packages. All variants share identical pin functions and layout symmetry per datasheet PD60107 revX.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN1,2,3 | High-side logic input | Inverted control signal for HO1,2,3; enables complementary PWM with LIN; 2.5V logic compatible. |
| LIN1,2,3 | Low-side logic input | Inverted control signal for LO1,2,3; synchronized with HIN for half-bridge operation. |
| HO1,2,3 | High-side gate drive output | Floating output referenced to VS1,2,3; drives gates of high-side N-MOS/IGBT with ±200 mA sink/source. |
| LO1,2,3 | Low-side gate drive output | Ground-referenced output; drives low-side switches with +420 mA sink capability. |
| VB1,2,3 | High-side floating supply | Bootstrap or isolated supply input (12–20 V) for each high-side driver stage. |
| VS1,2,3 | High-side floating return | Source/emitter node reference for corresponding high-side output; withstands −5 V to +1200 V transients. |
| CA+, CA−, CAO | Current sense amplifier I/O | Differential inputs (CA+/CA−) and single-ended output (CAO) for shunt-based phase current monitoring. |
| ITRIP | Over-current trip input | Analog comparator input tied to CAO; triggers full six-output shutdown when current exceeds threshold (470–670 mV). |
| FLT-CLR | Fault clear input | Negative-logic input that resets FAULT latch and restores outputs after over-current or UVLO event. |
| FAULT | Fault status output | Open-drain active-low signal indicating UVLO or over-current condition; pulls low during shutdown. |
| SD | Shutdown input | Negative-logic global disable; forces all six outputs low and asserts FAULT until cleared. |
| VCC | Logic & low-side supply | Fixed 10–20 V supply powering logic, low-side drivers, and amplifier; includes UVLO (7.2–9.6 V). |
| VSS, COM | Logic ground & low-side return | VSS = logic reference; COM = low-side power return path for LOx outputs and current sense amplifier. |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables direct bootstrap-driven high-side gate control up to 1200 V offset without external level shifters. |
| Matched propagation delay | 750/700 ns (typ.) across all six drivers ensures precise phase alignment in 3-phase PWM, reducing torque ripple. |
| Integrated current sense amplifier | Provides rail-to-rail output (0–5 V), 30 mV offset, and 4 nA bias for accurate, low-noise shunt-based current feedback. |
| Programmable over-current shutdown | ITRIP input accepts analog voltage from CAO; triggers simultaneous shutdown of all six outputs within 850 ns (typ.). |
| Independent UVLO per supply | Dual undervoltage lockout on VCC and each VBx supply prevents erratic switching during brownout or bootstrap failure. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar 3-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IR2235 | Same package and pinout; higher VBSUV thresholds (9.2–11.6 V) and 1200 V rating retained; optimized for 15–20 V VCC operation. | Preferred where tighter VCC UVLO hysteresis (1 V) and higher noise immunity are required in noisy industrial environments. | Select IR2235 when stable 15–20 V logic supply is guaranteed and enhanced UVLO margin is critical. |
| IRS2336D | Monolithic 3-phase driver with integrated bootstrap diodes; lower 600 V rating; no integrated current sense amplifier; 500 ns propagation delay. | Suitable for cost-sensitive 400 VAC motor drives without analog current feedback requirement. | Choose IRS2336D only for lower-voltage (<600 V), non-current-sensing applications where board space is constrained. |
Compared with IR2235, IR2233 offers wider VCC UVLO hysteresis (0.4 V) and lower threshold (7.2–9.6 V), making it more tolerant of marginal supply rails; versus IRS2336D, IR2233 adds 1200 V capability, matched timing, and integrated current sensing-critical for high-reliability, high-voltage inverters.

FAQ
What is the maximum allowable dV/dt at VS pins for reliable operation?
The IR2233 is specified for dV/dt immunity up to 50 V/ns at the VS1,2,3 pins, verified under test conditions per PD60107 revX. This allows stable operation in fast-switching SiC-based inverters where voltage transients exceed 10 kV/µs across the high-side switch. Layout best practices-including short, low-inductance paths between VS and COM-must be followed to maintain this rating.
Can the CAO output drive an ADC input directly?
Yes, CAO provides a rail-to-rail output (0–5 V) with 20 mV low-level and 5.4 V high-level voltage compliance, 4 nA input bias, and 50–70 dB PSRR/CMRR-making it compatible with 12-bit to 16-bit SAR or sigma-delta ADCs without external buffering. For optimal SNR, use a 100 Ω series resistor and 10 nF RC filter at the ADC input.
How does the ITRIP blanking time prevent false triggering during switching transitions?
The IR2233 incorporates a fixed 400 ns internal blanking window after each HIN/LIN edge, during which the ITRIP comparator is disabled. This prevents false over-current detection caused by transient voltage spikes across the shunt resistor during gate switching, ensuring only sustained overloads trigger shutdown-critical for reliable inverter operation under PWM stress.
Is the FLT-CLR function synchronous or asynchronous with respect to logic inputs?
FLT-CLR is asynchronous: asserting FLT-CLR low immediately clears the FAULT latch and restores normal output operation regardless of HIN/LIN states or clock edges. This enables immediate recovery from transient faults without waiting for PWM cycle alignment, supporting safety-critical restart protocols in industrial drives.
