Product details
Overview
IR2133SPBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with six independent gate drive outputs (HO1–HO3, LO1–LO3), designed for N-channel MOSFET/IGBT half-bridge configurations in motor drives and inverters. It supports up to 600 V offset voltage, delivers ±200 mA / +420 mA peak output current, features 750 ns / 700 ns typical turn-on/turn-off propagation delay, 250 ns matched deadtime, and integrated current-sense amplifier with over-current shutdown.
For engineers reviewing the IR2133SPBF datasheet, IR2133SPBF pinout, IR2133SPBF application, or IR2133SPBF equivalent, key selection considerations include bootstrap-compatible floating channel operation up to 600 V, 2.5 V logic compatibility, undervoltage lockout per channel, fault-clear functionality via FLT-CLR, and analog current feedback using external sense resistor.
Technical Context
The IR2133SPBF integrates three independent high-side and low-side drivers built on proprietary HVIC technology, enabling robust monolithic construction for 600 V-rated systems. Each high-side channel uses floating bootstrap supply (VB1–VB3) referenced to VS1–VS3, with dV/dt immunity and negative transient tolerance.
It embeds a rail-to-rail operational amplifier (CA+, CA−, CAO) for real-time bridge current monitoring and a dedicated ITRIP comparator with 400 ns blanking time. Shutdown (SD) and fault-clear (FLT-CLR) inputs operate with negative logic, and FAULT output is open-drain with active-low assertion on over-current or UVLO events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET max | 600 V - Maximum allowable high-side floating supply offset vs. COM, defining safe operating range for 3-phase inverter legs. |
| IO+ / IO− | 200 mA / 420 mA - Peak source/sink current per output, sufficient to drive gate capacitance of medium-power MOSFETs at >20 kHz switching. |
| ton / toff (typ.) | 750 ns / 700 ns - Propagation delays matched across all six channels, minimizing timing skew in synchronized PWM control. |
| Deadtime (typ.) | 250 ns - Built-in non-overlap interval between LS turn-off and HS turn-on, preventing shoot-through in half-bridge stages. |
| VOUT range | 10–20 V - Adjustable gate drive supply range, supporting standard 12 V or 15 V gate bias while tolerating 25 V transients. |
| Logic threshold | 2.2 V VIH / 0.8 V VIL - 2.5 V–compatible input interface, enabling direct connection to microcontrollers and FPGA I/O without level-shifting. |
| ITRIP threshold | 470–670 mV - Voltage trip point at CA+ input, calibrated to detect over-current via external shunt resistor (e.g., 5 mΩ → 1–1.3 A fault level). |
Pinout & Package
IR2133SPBF is packaged in a 28-lead SOIC (wide body) surface-mount package with exposed thermal pad (RoHS-compliant, PbF). Pin assignments are validated per Infineon PD60107 revX datasheet and match industry-standard 3-phase driver layout conventions.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN1–HIN3 | High-side logic input | Inverted control signal for HO1–HO3; enables complementary PWM with LINx for half-bridge switching. |
| LIN1–LIN3 | Low-side logic input | Inverted control signal for LO1–LO3; synchronized with HINx but phase-shifted for deadtime insertion. |
| HO1–HO3 | High-side gate drive output | Floating output referenced to VS1–VS3; drives gates of high-side N-MOSFETs/IGBTs in bootstrap configuration. |
| LO1–LO3 | Low-side gate drive output | Ground-referenced output; directly drives low-side switches with fast edge rates (90 ns rise, 40 ns fall). |
| VB1–VB3 | High-side floating supply | Bootstrap capacitor connection point for each high-side driver; must be ≥10 V above VSx to ensure full enhancement. |
| VS1–VS3 | High-side floating return | Source/emitter node of high-side power device; serves as local ground reference for corresponding VBx and HOx. |
| VCC | Fixed logic supply | Provides power for internal logic, low-side drivers, and op-amp circuitry; regulated 10–20 V input required. |
| COM | Power ground return | Common return path for all low-side outputs and current-sense amplifier; must be low-inductance connection. |
| ITRIP | Over-current trip input | Analog input tied to CA+; compares sensed shunt voltage against internal threshold to trigger global shutdown. |
| FLT-CLR | Fault clear input | Negative-logic enable: pulsed low clears FAULT latch after over-current or UVLO condition is resolved. |
| SD | Shutdown input | Negative-logic global disable: forces all six outputs low and asserts FAULT until cleared. |
| FAULT | Fault status output | Open-drain, active-low signal indicating UVLO (VCC or VBx) or over-current event; requires pull-up resistor. |
| CA+, CA−, CAO | Current amplifier I/O | Differential input pair (CA+, CA−) with rail-to-rail output (CAO); provides buffered analog current feedback for closed-loop control. |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables bootstrap-based high-side drive up to 600 V without isolated supplies, reducing BOM count and layout complexity. |
| Matched propagation delay | ≤±50 ns variation across all six channels ensures precise PWM synchronization critical for low-torque ripple in BLDC/PMSM drives. |
| Integrated current-sense amplifier | Eliminates need for external op-amp; provides 5–10 V/µs slew rate and 70 dB CMRR for accurate shunt-based phase current measurement. |
| Programmable over-current protection | ITRIP input accepts 470–670 mV threshold; blanking time (400 ns) prevents false triggering during switch transition. |
| Independent UVLO per supply | Dual undervoltage lockout (VCC and VB1–VB3) with hysteresis prevents erratic switching during brown-out 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 |
|---|---|---|---|
| IR2130SPBF | Lower 400 V offset rating; no integrated current amplifier; 20-pin SOIC package. | Suitable for lower-bus-voltage (<400 V) inverters where external current sensing is preferred. | Select when cost sensitivity outweighs need for integrated analog feedback and higher voltage margin. |
| IRS2330JPbF | 600 V rating; includes bootstrap diode integration; 28-pin SOIC; lacks ITRIP/CAO pins. | Optimized for space-constrained designs needing simplified bootstrap network but no analog current monitoring. | Choose when board area is limited and over-current detection is handled externally or digitally. |
Compared with IR2133SPBF, IR2130SPBF trades voltage headroom and current sensing for lower cost and smaller footprint, while IRS2330JPbF reduces external component count at the expense of analog feedback flexibility-making IR2133SPBF optimal for closed-loop motor control requiring real-time current data.

FAQ
What is the maximum bootstrap capacitor voltage rating required for IR2133SPBF?
The VBx pins tolerate up to 625 V absolute maximum, but recommended operating range is VSx + 10 V to VSx + 20 V. For 600 V bus applications, a 25 V rated ceramic or film capacitor (e.g., 100 nF X7R) is standard. Exceeding 25 V transient rating risks overstress during switching transients.
Can IR2133SPBF drive SiC MOSFETs directly?
Yes-its 200 mA source / 420 mA sink capability, 750 ns propagation delay, and 90 ns rise time meet gate drive requirements for ≤30 A SiC MOSFETs at ≤100 kHz. However, external negative turn-off bias or active Miller clamp may be needed for robust dv/dt immunity in high-speed designs.
How does the ITRIP blanking time prevent false over-current trips?
The internal 400 ns blanking window disables ITRIP comparison immediately after HO/LO transitions, suppressing voltage spikes from parasitic inductance during switch commutation. This ensures only sustained over-current conditions-exceeding threshold for >400 ns-trigger shutdown, improving system reliability.
Is FAULT output compatible with 3.3 V microcontrollers?
Yes-the FAULT pin is open-drain with VSS-referenced output and 70 Ω typical on-resistance. A 10 kΩ pull-up to 3.3 V yields valid logic-low (<0.4 V) and logic-high (~3.3 V), enabling direct interface with ARM Cortex-M or RISC-V GPIOs without level translation.
