Product details
Overview
IR2233STRPBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with six independent gate drive outputs (three high-side and three low-side), rated for up to 1200V offset voltage, ±200 mA / +420 mA peak 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 stages in industrial AC drives.
For engineers reviewing the IR2233STRPBF datasheet, IR2233STRPBF pinout, IR2233STRPBF application, or IR2233STRPBF equivalent, key selection criteria include 1200V floating channel capability, matched propagation delays across all six channels, 2.5V logic compatibility, integrated current trip function, and fault-clear input with open-drain FAULT output.
Technical Context
The IR2233STRPBF implements three independent half-bridge drivers using proprietary HVIC technology, enabling robust monolithic construction for operation up to 1200V VS offset. Each high-side channel uses bootstrap-supplied floating gate drive with undervoltage lockout (VBSUV+ = 9.2–11.6 V) and dV/dt immunity.
It features a dedicated current-sense amplifier (CA+, CA−, CAO) with 5–10 V/µs slew rate, 50–70 dB CMRR/PSRR, and programmable over-current trip via external resistor. Shutdown (SD) and fault-clear (FLT-CLR) inputs operate with negative logic and internal 5.2V zener clamping.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VS Offset Max | 1200 V - supports high-side IGBT/MOSFET switching in 690VAC industrial motor drives |
| IO+ / IO− | 200 mA / 420 mA - sufficient gate charge delivery for 30A–60A IGBTs at ≤20 kHz |
| ton / toff (typ) | 750 / 700 ns - enables clean PWM timing control up to 100 kHz with minimal shoot-through risk |
| Deadtime (typ) | 250 ns - fixed internal deadtime prevents cross-conduction in complementary half-bridge pairs |
| VCC Range | 12–20 V - compatible with standard 15V isolated DC-DC supplies and transient-tolerant to 25V |
| Logic Threshold | 2.5V compatible - interfaces directly with microcontroller GPIO without level-shifting |
| Current Sense Amp | CAO output swing 0–5.4 V - provides rail-to-rail analog feedback for closed-loop current regulation |
Pinout & Package
IR2233STRPBF is housed in a 28-lead SOIC (wide-body) package with gull-wing leads, optimized for thermal dissipation and creepage in high-voltage motor control PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN1,2,3 | High-side logic input | Inverted PWM input controlling HO1–HO3; 2.5V–5V compatible, internally clamped to 5.2V |
| LIN1,2,3 | Low-side logic input | Inverted PWM input controlling LO1–LO3; matches HIN timing for synchronous 3-phase commutation |
| HO1,2,3 | High-side gate output | Floating N-channel driver output referenced to VS1–VS3; 200 mA sink, 420 mA source |
| LO1,2,3 | Low-side gate output | Ground-referenced driver output; matched propagation delay to HOx for precise deadtime control |
| VB1,2,3 | Floating supply input | Bootstrap capacitor connection point for high-side gate drive; rated to 1225 V max |
| VS1,2,3 | Floating return | High-side source node return; withstands −5V to +1200V transients relative to COM |
| ITRIP | Over-current sense input | Analog input tied to external shunt; 470–670 mV threshold triggers full six-output shutdown |
| FAULT | Open-drain fault indicator | Active-low signal indicating UVLO or over-current; requires external pull-up for system-level monitoring |
| FLT-CLR | Fault clear input | Negative-logic input that resets FAULT latch and re-enables outputs after fault condition clears |
| SD | Global shutdown input | Negative-logic input disabling all six outputs immediately; overrides all other controls |
| CA+, CA−, CAO | Current amplifier I/O | Differential input pair with rail-to-rail output; enables real-time phase current measurement and protection |
| VCC, VSS, COM | Fixed supply & grounds | VCC powers logic and low-side drivers (12–20 V); VSS = logic ground; COM = low-side power return |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables direct high-side N-channel MOSFET/IGBT drive up to 1200V without external level shifters |
| Matched propagation delay | Ensures identical timing across all six outputs (±50 ns typical), critical for balanced 3-phase PWM |
| Integrated current sense amplifier | Eliminates need for external op-amp; provides 0–5.4 V output proportional to shunt voltage with 50–70 dB rejection |
| Independent UVLO per supply | VCC and each VBS have separate hysteresis-based lockout (0.4–1.0 V), preventing erratic switching during brownout |
| Programmable over-current shutdown | ITRIP threshold set by external resistor; blanking time of 400 ns avoids false trips during switching transients |

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 |
|---|---|---|---|
| IR2235STRPBF | Same pinout and architecture but includes internal 100Ω gate resistors; higher VBSUV threshold (10.4 V typ) | Better suited for high-noise environments where gate resistor integration reduces EMI sensitivity | Select when minimizing external component count and improving noise immunity outweighs need for adjustable gate resistance |
| IRS2330JPbF | 1200V-rated 3-phase driver with integrated bootstrap diodes; no current-sense amplifier; different pinout (28-pin DIP) | Lacks analog current feedback but simplifies layout with on-chip bootstrap diodes for cost-sensitive inverters | Select when current sensing is handled externally and board space allows DIP footprint |
Compared with IR2235STRPBF and IRS2330JPbF, the IR2233STRPBF uniquely balances integrated current sensing, 1200V robustness, and SOIC packaging-making it optimal for space-constrained, high-fidelity motor control where real-time phase current monitoring is required.

FAQ
What is the maximum allowable dV/dt at the VS pins?
The IR2233STRPBF is specified for 50 V/ns dV/dt immunity on its high-side floating supply returns (VS1–VS3). This rating ensures reliable operation during fast-switching events in IGBT-based inverters, preventing false triggering or latch-up even under severe bus transients common in 1200V systems.
Can the current-sense amplifier be used for closed-loop motor control?
Yes-the CA+, CA−, and CAO pins provide a fully differential, rail-to-rail output amplifier with 5–10 V/µs slew rate and 50–70 dB CMRR. When paired with a precision shunt resistor, it delivers accurate analog current feedback suitable for FOC (field-oriented control) loops with bandwidth up to 200 kHz.
How does the FLT-CLR function interact with the SD input?
FLT-CLR resets the internal fault latch and restores normal operation only after the root cause (e.g., over-current or UVLO) has cleared. The SD input forces immediate, unconditional shutdown of all six outputs regardless of fault state-and remains active until SD is deasserted. SD takes precedence over FLT-CLR.
Is external bootstrap diode required for VB1–VB3 connections?
No-external bootstrap diodes are not required. The IR2233STRPBF does not integrate bootstrap diodes; however, standard ultrafast 1N4148 or Schottky diodes (e.g., RB050M-30) are recommended per channel to charge the VBx capacitors during low-side conduction, as confirmed in Infineon Application Note AN-978.
