Product details
Overview
IR2133STR from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent half-bridge gate drive channels, 600 V high-side offset rating, ±200 mA / +420 mA output drive capability, 750 ns / 700 ns typical turn-on/turn-off propagation delay, and integrated current-sense amplifier for over-current protection - used in motor inverters for industrial BLDC and PMSM drives.
For engineers reviewing the IR2133STR datasheet, IR2133STR pinout, IR2133STR application, or IR2133STR equivalent, key selection criteria include bootstrap-compatible floating channel operation up to 600 V, matched propagation delays across all six outputs, 2.5 V logic compatibility, undervoltage lockout per supply rail, and fault-clear functionality via FLT-CLR pin.
Technical Context
The IR2133STR integrates three isolated high-side (HO1–HO3) and three low-side (LO1–LO3) drivers using proprietary HVIC technology, enabling robust monolithic construction for 600 V-rated applications. Each high-side channel operates with a floating VBx/VSx supply pair and tolerates dV/dt transients without false triggering.
It features an internal operational amplifier with CA+, CA−, and CAO pins for analog current feedback via external sense resistor, plus dedicated ITRIP input with 470–670 mV threshold and 400 ns blanking time. Shutdown (SD) and fault clear (FLT-CLR) are active-low logic inputs with hysteresis and clamped 5.2 V zener protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-side offset voltage | 600 V max - enables direct driving of N-channel MOSFETs/IGBTs in high-side configuration of 3-phase inverter legs up to 600 V bus voltage |
| Output drive current | +200 mA / −420 mA - sufficient to rapidly charge/discharge gate capacitance of power devices up to ~1 nF at 20 kHz switching |
| Propagation delay (typ.) | 750 ns / 700 ns (ton/toff) - matched timing across all six outputs simplifies PWM deadtime management in high-frequency inverters |
| Deadtime (typ.) | 250 ns - built-in interlock prevents shoot-through during HS-to-LS and LS-to-HS transitions |
| Logic supply range | 10–20 V (VCC) - supports standard 12 V or 15 V control rails while allowing transient headroom up to 25 V |
| Current sense amplifier | Input offset ≤30 mV, CMRR ≥70 dB - enables accurate low-side or high-side current sensing with external shunt resistor |
| UVLO thresholds | VBSUV+ = 8.6 V (typ.), VCCUV+ = 8.6 V (typ.) - ensures stable gate drive only when both floating and logic supplies are within safe operating window |
Pinout & Package
IR2133STR is supplied in a 28-lead SOIC (wide-body) package with gull-wing leads, optimized for thermal performance and PCB layout in motor drive applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN1–HIN3 | High-side logic inputs | Inverted PWM inputs controlling HO1–HO3; compatible with 2.5 V CMOS/LSTTL; each has 310 ns input filter |
| LIN1–LIN3 | Low-side logic inputs | Inverted PWM inputs controlling LO1–LO3; same logic interface and filtering as HIN pins |
| HO1–HO3 | High-side gate drive outputs | Floating outputs referenced to VS1–VS3; capable of sourcing 200 mA and sinking 420 mA |
| LO1–LO3 | Low-side gate drive outputs | Ground-referenced outputs referenced to COM; same drive strength as HO outputs |
| VB1–VB3 | High-side floating supply inputs | Bootstrap capacitor connections for high-side gate drive; rated up to 625 V absolute |
| VS1–VS3 | High-side floating return nodes | Source terminals of high-side power switches; define local ground for respective HO outputs |
| VCC | Fixed logic supply | Powers internal logic, LSI drivers, and op amp; range 10–20 V with UVLO protection |
| COM | Low-side common return | Reference node for LO outputs and internal circuitry; must be connected to power ground |
| VSS | Logic ground | Digital ground reference for inputs (HIN/LIN/SD/FLT-CLR/ITRIP); tied to COM in most designs |
| ITRIP | Over-current trip input | Analog input monitoring amplified shunt voltage; triggers shutdown when >670 mV (typ.) |
| FLT-CLR | Fault clear input | Active-low signal to reset FAULT latch after over-current or UVLO event |
| SD | Shutdown input | Active-low global disable for all six outputs; overrides PWM inputs |
| FAULT | Fault status output | Open-drain output pulled low during UVLO or over-current; requires external pull-up |
| CA+, CA−, CAO | Current amplifier I/O | Differential inputs and single-ended output for real-time analog current feedback path |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables bootstrap-based high-side drive up to 600 V without external level shifters or isolated supplies |
| Matched propagation delays | Ensures consistent timing across all six outputs, reducing need for external deadtime compensation in 3-phase PWM |
| Integrated current sense amplifier | Provides precision analog feedback (≤30 mV offset, 70 dB CMRR) for closed-loop motor current control |
| Independent UVLO per supply rail | Prevents partial or unstable gate drive by disabling outputs if either VCC or any VBx falls below 8.6 V (typ.) |
| Programmable fault response | Combines ITRIP threshold detection, 400 ns blanking, and FLT-CLR pin for controlled recovery from over-current events |

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 |
|---|---|---|---|
| IR2135STR | Same pinout and function but rated for 600 V offset and higher VCC UVLO (10.4 V typ.) | Preferred where tighter VCC regulation or higher noise immunity is required | Select IR2135STR when system VCC stability is marginal or EMI environment is severe |
| IRS2330JPbF | Monolithic 3-phase driver with integrated bootstrap diodes; 600 V rating; no separate CA amplifier | Lacks analog current feedback path; uses digital fault reporting only | Choose IRS2330JPbF for cost-sensitive, space-constrained designs where current feedback is handled externally |
Compared with IR2133STR, IR2135STR offers enhanced VCC UVLO hysteresis for improved supply noise rejection, while IRS2330JPbF reduces BOM count via integrated bootstrap diodes but sacrifices the precision analog current sensing capability essential for FOC-based motor control.

FAQ
What is the maximum allowable high-side bus voltage for IR2133STR?
The IR2133STR supports a maximum high-side floating supply offset voltage (VSx) of 600 V relative to its corresponding VBx supply, verified per Absolute Maximum Ratings table. This rating applies under continuous DC conditions with proper PCB layout and thermal management; transient spikes beyond 600 V must be clamped externally to avoid damage.
Can IR2133STR drive both MOSFETs and IGBTs?
Yes - IR2133STR is explicitly qualified to drive both N-channel power MOSFETs and IGBTs in 3-phase bridge configurations. Its ±200 mA / +420 mA peak output current and 10–20 V gate drive range accommodate typical gate charge requirements for devices up to 30 A/600 V, as confirmed in the Functional Description and Application Notes PD60107.
How does the current sense amplifier interface with external circuitry?
The CA+, CA−, and CAO pins form a differential-input, single-ended-output instrumentation amplifier. CA+ and CA− connect across an external current sense resistor; CAO delivers amplified voltage proportional to sensed current. Input offset is ≤30 mV, and CMRR exceeds 70 dB, enabling accurate measurement even with common-mode voltages near VSS or COM.
Is IR2133STR pin-compatible with IR2135STR?
Yes - IR2133STR and IR2135STR share identical pin assignments, package dimensions, and functional block diagram per datasheet PD60107 revX. The primary difference lies in UVLO thresholds: IR2135STR uses higher VCC and VBS UVLO points (10.4 V vs. 8.6 V typ.), making it more tolerant of supply droop but otherwise drop-in replaceable in existing layouts.
