Product details
Overview
IR2133PBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent half-bridge gate drivers, 600 V high-side offset rating, ±200 mA / +420 mA peak output current, 750 ns / 700 ns typical turn-on/turn-off propagation delay, and integrated current-sense amplifier for over-current protection in motor inverter stages.
For engineers reviewing the IR2133PBF datasheet, IR2133PBF pinout, IR2133PBF application, or IR2133PBF equivalent, key selection considerations include bootstrap-compatible floating channel operation up to 600 V, matched propagation delays across all six channels, undervoltage lockout per supply rail, and fault-clear functionality via FLT-CLR pin.
Technical Context
The IR2133PBF integrates three isolated high-side and three referenced low-side drivers using proprietary HVIC technology, enabling robust monolithic construction for 3-phase inverter topologies. Each high-side channel operates with floating VBx/VSx supplies and tolerates dV/dt transients up to 50 V/ns while maintaining logic integrity at VS = COM −5 V to COM +600 V.
It features an internal operational amplifier (CA+, CA−, CAO) with 5–10 V/µs slew rate and 50–70 dB CMRR/PSRR, allowing analog current feedback via external sense resistor. Over-current shutdown triggers within 850 ns (typ.) and asserts open-drain FAULT signal, cleared only by active-low FLT-CLR pulse.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| High-side offset voltage | 600 V max - supports bootstrap-fed N-channel MOSFET/IGBT high-side switches in 3-phase inverters up to 400 V AC line. |
| Output drive current | +200 mA / −420 mA - sufficient to charge/discharge 1 nF gate capacitance in <100 ns, enabling >100 kHz PWM switching. |
| Propagation delay (ton/toff) | 750 / 700 ns typ. - matched across all six channels to minimize phase skew and prevent shoot-through in synchronous 3-phase control. |
| Dead time | 250 ns typ. - fixed internal delay between LS turn-off and HS turn-on ensures safe commutation without external timing circuitry. |
| Gate drive supply range | 10–20 V (VCC), 10–20 V (VBx) - compatible with standard 12 V/15 V bias rails and tolerant of transient overvoltage up to 25 V. |
| Current sense amplifier | Input offset ≤30 mV, slew rate 5–10 V/µs - enables accurate real-time phase current monitoring with <1 µs blanking window (400 ns typ.). |
Pinout & Package
IR2133PBF is housed in a 28-lead SOIC (wide-body) package with gull-wing leads, optimized for thermal dissipation and high-voltage isolation in motor drive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN1, HIN2, HIN3 | High-side logic input | Inverted-phase PWM inputs controlling HO1–HO3; 2.5 V logic compatible with CMOS/LSTTL. |
| LIN1, LIN2, LIN3 | Low-side logic input | Inverted-phase PWM inputs controlling LO1–LO3; synchronized with HIN for complementary drive. |
| HO1, HO2, HO3 | High-side gate output | Floating outputs referenced to VS1–VS3; drive N-channel devices in high-side configuration. |
| LO1, LO2, LO3 | Low-side gate output | Ground-referenced outputs driving low-side N-channel switches directly from VCC. |
| VB1–VB3 | High-side floating supply | Bootstrap capacitor connection points; each powers its respective high-side driver stage. |
| VS1–VS3 | High-side floating return | Source node references for HO1–HO3; must be tied to power device source terminals. |
| VCC | Logic & low-side supply | Fixed 10–20 V rail powering logic, low-side drivers, and amplifier circuitry. |
| COM | Low-side power return | Common return for LOx outputs and current-sense amplifier ground reference. |
| ITRIP | Over-current trip input | Analog input sensing voltage across external shunt; triggers shutdown when ≥570 mV (typ.). |
| FLT-CLR | Fault clear input | Active-low asynchronous reset for FAULT latch after over-current or UVLO event. |
| FAULT | Fault status output | Open-drain signal pulled low during UVLO or over-current; requires external pull-up. |
| CA+, CA−, CAO | Current amplifier I/O | Differential input pair and single-ended output for closed-loop phase current feedback. |
| SD | Shutdown input | Global disable for all six outputs; active-high with 1.9 V threshold (typ.). |
| VSS | Logic ground | Reference for all logic inputs and amplifier bias; isolated from COM in layout-critical designs. |
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 delay | ≤50 ns channel-to-channel skew ensures precise timing alignment across all six outputs for clean 3-phase commutation. |
| Integrated current-sense amplifier | Eliminates need for external op-amp and reduces BOM count; supports fast over-current response (<900 ns). |
| Independent UVLO per supply rail | VCC and each VBx supply monitored separately with hysteresis (0.4 V for IR2133 variants), preventing erratic switching during brownout. |
| Programmable blanking time | 400 ns internal ITRIP blanking window suppresses false trips during switching transients without external RC networks. |

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 |
|---|---|---|---|
| IR2135PBF | Higher VBS UVLO threshold (10.4 V vs. 8.6 V) and 12–20 V gate drive range; identical pinout and function. | Better suited for 15 V bias rails with tighter UVLO margin; same 600 V offset rating and timing specs. | Select IR2135PBF when VCC is stabilized near 15 V and higher UVLO hysteresis (1 V) improves noise immunity. |
| IRS2330JPbF | Integrated bootstrap diodes, lower 500 ns max propagation delay, but no on-chip current amplifier or ITRIP input. | Requires external current sensing and comparator; better for space-constrained designs where analog feedback is handled elsewhere. | Choose IRS2330JPbF when board area is critical and current monitoring is implemented digitally or with external analog front-end. |
Compared with IR2133PBF, IR2135PBF offers enhanced supply rejection at 15 V operation, while IRS2330JPbF trades integrated protection for reduced footprint-making IR2133PBF optimal where analog current feedback and single-chip fault management are required.

FAQ
What is the maximum allowable dV/dt at the VS pins of IR2133PBF?
The IR2133PBF is rated for dV/dt immunity up to 50 V/ns at the VS1–VS3 pins, verified under conditions where VBx = 15 V and VSx transitions from COM −5 V to COM +600 V. This specification ensures reliable operation in fast-switching inverter legs with high parasitic inductance, preventing false triggering of high-side logic.
Can IR2133PBF drive both MOSFETs and IGBTs?
Yes-IR2133PBF is explicitly qualified to drive both N-channel power MOSFETs and IGBTs, as confirmed in the datasheet's "Description" and "Absolute Maximum Ratings" sections. Its ±200 mA / +420 mA peak output current and 10–20 V gate drive range match typical gate charge requirements for 30–100 A IGBT modules and medium-power MOSFETs used in 3-phase inverters.
How does the internal current amplifier differ from a standard op-amp?
The IR2133PBF's CA+ / CA− / CAO amplifier features rail-to-rail input/output swing, 5–10 V/µs slew rate, and 50–70 dB CMRR/PSRR-optimized for direct connection to low-value shunt resistors. Unlike general-purpose op-amps, it includes built-in blanking (400 ns typ.) and feeds directly into the ITRIP comparator, eliminating external signal conditioning components.
Is external bootstrap diode required for IR2133PBF?
Yes-an external fast-recovery bootstrap diode (e.g., 1N4148WS or equivalent) is mandatory between VCC and VBx pins for each high-side channel. The IR2133PBF lacks integrated bootstrap diodes (unlike IRS2330), so omission will prevent proper high-side gate charging and cause driver failure during continuous PWM operation.
