Product details
Overview
IR2133STRPBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with six independent gate drive outputs (HO1–HO3, LO1–LO3), floating channel architecture for bootstrap operation up to +600 V, 200 mA/420 mA peak output current, 750 ns/700 ns typical turn-on/turn-off propagation delay, and integrated current-sense amplifier with ITRIP fault shutdown. It is used in motor inverters for industrial BLDC and PMSM drives.
For engineers reviewing the IR2133STRPBF datasheet, IR2133STRPBF pinout, IR2133STRPBF application, or IR2133STRPBF equivalent, key selection considerations include high-side offset voltage rating (600 V), matched propagation delays across all channels, undervoltage lockout thresholds per supply rail (VCC and VBS), and integrated analog current feedback via CA+/CA−/CAO pins.
Technical Context
The IR2133STRPBF integrates three independent half-bridge drivers with matched propagation delays (750 ns ton / 700 ns toff) and 250 ns programmable deadtime, enabling precise synchronous PWM control in 3-phase inverter topologies. Its floating high-side channels operate with VS offset up to +600 V and tolerate dV/dt transients up to 50 V/ns.
It features a dedicated current-sense amplifier (CA+, CA−, CAO) with 5–10 V/µs slew rate, ±30 mV input offset, and 70 dB CMRR/PSRR, allowing direct connection to a shunt resistor for real-time phase current monitoring. Fault detection triggers simultaneous shutdown of all six outputs via ITRIP or SD inputs, signaled by open-drain FAULT and cleared by FLT-CLR.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET max | +600 V - maximum high-side floating supply offset relative to COM, enabling direct drive of N-channel MOSFETs/IGBTs in 600 V-class inverters. |
| IO+/IO− | 200 mA / 420 mA - peak pulsed source/sink current per output, sufficient to charge/discharge 1000 pF gate capacitance within 90 ns rise / 40 ns fall time. |
| ton/toff (typ.) | 750 ns / 700 ns - matched propagation delays across all six channels, minimizing timing skew in high-frequency (≥20 kHz) PWM applications. |
| VOUT range | 10–20 V - gate drive supply range for VCC and VBx, supporting logic-compatible 12 V or robust 15–18 V gate bias for low RDS(on) switching. |
| Deadtime (typ.) | 250 ns - built-in non-overlap interval between LS turn-off and HS turn-on, preventing shoot-through in hard-switched 3-phase bridges. |
| ITRIP threshold | 470–670 mV - positive-going trip voltage at ITRIP pin, corresponding to shunt-resistor-based overcurrent detection with 400 ns blanking window. |
| Logic compatibility | 2.5 V - minimum logic-high input voltage for HIN/LIN/SD/FLT-CLR, ensuring interoperability with 3.3 V microcontrollers without level-shifting. |
Pinout & Package
IR2133STRPBF is housed in a 28-lead SOIC (wide-body) package with gull-wing leads, optimized for thermal dissipation and high-voltage isolation in motor control PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN1–HIN3 | High-side logic input | Inverted-phase PWM inputs controlling HO1–HO3; tolerant to −5 V to +600 V common-mode offset on VS pins. |
| LIN1–LIN3 | Low-side logic input | Inverted-phase PWM inputs controlling LO1–LO3; referenced to VSS/COM, compatible with 2.5–5 V logic. |
| HO1–HO3 | High-side gate drive output | Floating outputs referenced to VS1–VS3; deliver 200 mA source / 420 mA sink into gate loads. |
| LO1–LO3 | Low-side gate drive output | Ground-referenced outputs; drive N-MOSFET gates directly from VCC-supplied buffer stage. |
| VB1–VB3 | High-side floating supply | Bootstrap capacitor connection points; each supplies gate drive for one high-side channel (HOx). |
| VS1–VS3 | High-side floating return | Source/negative terminals of high-side power switches; define local ground reference for VBx and HOx. |
| CA+, CA−, CAO | Current sense amplifier I/O | Differential input (CA+/CA−) and single-ended output (CAO) for closed-loop phase current sensing and protection. |
| ITRIP, SD, FLT-CLR | Protection control inputs | Active-low fault initiation (ITRIP), global shutdown (SD), and fault clear (FLT-CLR); all 2.5 V logic compatible. |
| FAULT | Fault status indicator | Open-drain output pulled low during UVLO or overcurrent; requires external pull-up for system-level interrupt signaling. |
| VCC, VSS, COM | Power and ground rails | VCC powers logic and low-side drivers; VSS = logic ground; COM = low-side power return (shared with LOx sinks). |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables bootstrap gate drive for high-side N-MOSFETs/IGBTs up to +600 V VS offset, eliminating need for isolated DC-DC supplies. |
| Matched propagation delay | 750 ns (ton) / 700 ns (toff) across all six outputs ensures synchronized switching and minimizes torque ripple in motor control. |
| Integrated current-sense amplifier | Provides rail-to-rail output (CAO), 70 dB CMRR, and 400 ns blanking window-enabling accurate, noise-immune phase current measurement. |
| Independent UVLO per supply | Dual undervoltage lockout (VCCUV: 7.6–9.6 V; VBSUV: 7.6–9.6 V) prevents erratic operation during brown-out or bootstrap capacitor discharge. |
| Programmable deadtime | 250 ns internal deadtime plus external RC tuning capability avoids cross-conduction in high-power 3-phase inverters. |
Applications

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 | Same 28-pin SOIC footprint and 600 V rating, but lacks integrated current-sense amplifier (CA+/CA−/CAO) and ITRIP functionality. | Suitable for simpler inverters where external current sensing is acceptable; no analog feedback path onboard. | Select when cost sensitivity outweighs need for integrated current monitoring and fault blanking. |
| IRS2330JPbF | Higher 1200 V VS rating and enhanced dV/dt immunity (±100 V/ns), but uses 28-pin PDIP package and has longer propagation delays (900/850 ns). | Better suited for high-bus-voltage solar inverters or traction drives; less optimal for compact, high-frequency BLDC designs. | Select when system bus exceeds 600 V or extreme noise immunity is required, accepting larger package and timing penalty. |
Compared with IR2133STRPBF, IR2130SPBF omits current-sense integration-requiring external circuitry for overcurrent protection-while IRS2330JPbF trades higher voltage rating and noise resilience for slower switching and through-hole assembly.

FAQ
What is the maximum allowable VS offset voltage for IR2133STRPBF?
The IR2133STRPBF supports a maximum high-side floating supply offset voltage (VS) of +600 V relative to COM, verified under recommended operating conditions with VBS = 15 V. This rating applies to IR2133/IR2135 variants; IR2233/IR2235 support 1200 V but are not functionally identical to IR2133STRPBF.
Does IR2133STRPBF require external bootstrap diodes and capacitors?
Yes-each high-side channel (HO1–HO3) requires an external bootstrap diode and capacitor connected between VBx and VSx. The diode must withstand ≥600 V reverse voltage and ≥200 mA forward current; typical capacitor values range from 0.1 µF to 1 µF X7R ceramic, sized per switching frequency and gate charge.
How does the ITRIP overcurrent protection function?
The ITRIP pin monitors voltage across an external shunt resistor. When the differential input (CA+–CA−) exceeds 470–670 mV, the internal comparator triggers a 400 ns blanking window, then asserts FAULT and disables all six outputs. Fault clearance requires a low-to-high pulse on FLT-CLR.
Can IR2133STRPBF drive both MOSFETs and IGBTs?
Yes-the output drivers provide 200 mA source / 420 mA sink current and 10–20 V output swing, compatible with standard gate thresholds of 600 V N-channel MOSFETs and IGBTs. Layout must ensure low-inductance gate loops and proper Miller clamping for IGBTs to avoid unintended turn-on.
