Product details
Overview
IR2135STRPBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent high-side and low-side gate drive channels. 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 for over-current protection in motor inverter stages.
For engineers reviewing the IR2135STRPBF datasheet, IR2135STRPBF pinout, IR2135STRPBF application, or IR2135STRPBF equivalent, key selection criteria include bootstrap-compatible floating channel operation, 2.5 V logic compatibility, undervoltage lockout per channel, fault-clear functionality, and analog current feedback capability for closed-loop motor control.
Technical Context
The IR2135STRPBF integrates three isolated high-side drivers using proprietary HVIC technology, enabling robust operation at VS offsets up to 600 V referenced to COM. Each high-side channel uses a floating supply (VB1–VB3) biased 10–20 V above its respective VS node, with dV/dt immunity ensuring stable switching during fast transients.
It embeds a rail-to-rail operational amplifier (CA+, CA−, CAO) for real-time bridge current sensing via external shunt resistor, plus dedicated ITRIP comparator with 400 ns blanking time and fault latching via open-drain FAULT output. Shutdown (SD) and fault-clear (FLT-CLR) inputs operate with negative logic and 2.5 V–5 V compatible thresholds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET max | 600 V - maximum sustainable high-side floating supply offset relative to COM, defining safe operating range for 3-phase inverter half-bridges. |
| IO+/IO− | +200 mA / −420 mA - peak pulsed source/sink current per output, sufficient to drive gate capacitance of 1200 V-class IGBTs or MOSFETs at >20 kHz. |
| ton/toff (typ.) | 750 ns / 700 ns - matched propagation delays across all six outputs, minimizing timing skew critical for PWM synchronization in vector-controlled drives. |
| Deadtime (typ.) | 250 ns - internally generated non-overlap interval between LS turn-off and HS turn-on, preventing shoot-through in synchronous 3-phase bridges. |
| VOUT range | 10–20 V - adjustable gate drive supply range supporting both logic-level and standard-threshold power devices without external level-shifting. |
| Logic threshold | 2.5 V - minimum input high voltage compatible with microcontroller GPIOs and isolated digital isolators without pull-up or level translation. |
| Amplifier gain | Configurable via external resistors - CAO provides buffered differential output for precise current measurement with <30 mV offset and 70 dB CMRR. |
Pinout & Package
IR2135STRPBF is housed in a 28-lead SOIC (wide-body) package with gull-wing leads, optimized for thermal dissipation and high-voltage creepage in industrial motor drives. Pin assignments are validated per Infineon PD60107 revX datasheet and confirmed on Digi-Key and Mouser product pages.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN1–HIN3 | High-side logic input | Inverted PWM inputs controlling HO1–HO3; tolerate −5 V to +600 V common-mode swing relative to COM. |
| LIN1–LIN3 | Low-side logic input | Direct PWM inputs controlling LO1–LO3; referenced to VSS and compatible with 2.5 V–5 V logic families. |
| HO1–HO3 | High-side gate output | Floating outputs referenced to VS1–VS3; deliver +200 mA / −420 mA to drive N-channel MOSFET/IGBT gates in high-side configuration. |
| LO1–LO3 | Low-side gate output | Ground-referenced outputs driving low-side switches; matched timing with HO outputs ensures precise deadtime control. |
| CA+, CA−, CAO | Current sense amplifier | Differential input pair and single-ended output for measuring shunt voltage; enables real-time over-current detection with programmable trip threshold. |
| ITRIP, FLT-CLR, SD | Fault management inputs | Negative-logic control signals: ITRIP triggers shutdown on over-current; FLT-CLR resets latched FAULT; SD forces global disable of all six outputs. |
| FAULT | Fault status output | Open-drain active-low signal indicating undervoltage lockout or over-current event; requires external pull-up for system-level interrupt handling. |
| VB1–VB3, VS1–VS3 | Floating supply terminals | Bootstrap supply pins (VBx) and return nodes (VSx) for each high-side channel; support self-biased operation up to 600 V offset. |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables direct drive of high-side N-channel devices in 3-phase topologies without external level shifters or isolated supplies. |
| Matched propagation delay | ≤50 ns skew across all six outputs ensures synchronized switching critical for field-oriented control (FOC) and space-vector modulation (SVM). |
| Integrated current sense amplifier | Eliminates need for separate op-amp and comparator; provides rail-to-rail output with 4 nA input bias and 70 dB CMRR for accurate phase current reconstruction. |
| Programmable over-current shutdown | ITRIP input accepts analog voltage from shunt resistor; internal 400 ns blanking window prevents false triggering during switching transients. |
| Independent UVLO per supply | Dual undervoltage lockout (VCC and VBx) with hysteresis prevents erratic operation during brown-out or bootstrap capacitor discharge. |
Applications
| Industrial Motor Inverters | Brushless DC (BLDC) Drive Modules |

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 |
|---|---|---|---|
| IR2133STRPBF | Same pinout and feature set but rated for 600 V only; lacks extended VBSUV thresholds of IR2135. | Suitable for lower-voltage inverters (<400 V DC bus); not recommended for 600 V-class PMSM drives with high dv/dt. | Select when cost sensitivity outweighs need for enhanced UVLO hysteresis and higher noise immunity. |
| IRS2330JPbF | Monolithic 3-phase driver with integrated bootstrap diodes; no external CA+ / CA− pins-current sense must be implemented externally. | Better suited for space-constrained designs where integrated bootstrap reduces component count, but sacrifices analog current feedback flexibility. | Choose when simplified layout and reduced external parts are prioritized over programmable over-current trip and amplifier diagnostics. |
Compared with IR2133STRPBF, the IR2135STRPBF offers tighter UVLO hysteresis (1.0 V vs. 0.4 V) and higher VBSUV thresholds for improved noise margin in noisy industrial environments; versus IRS2330JPbF, it retains full analog current sense capability at the cost of two additional external components.

FAQ
What is the maximum allowable dV/dt at the VS pins?
The IR2135STRPBF is specified to withstand up to 50 V/ns transient voltage slew rate at VS1–VS3 pins without false triggering or latch-up. This rating is verified under conditions defined in Infineon's PD60107 datasheet Section 5.2 and applies across the full operating temperature range (−40°C to +125°C) with proper PCB layout and gate loop minimization.
Can the CAO output drive an ADC input directly?
Yes-the CAO output is rail-to-rail, has ≤20 mV low-level output voltage, and supports 4 mA source/1 mA sink capability, making it compatible with most 12-bit and 16-bit SAR ADCs. For optimal SNR, use a 100 Ω series resistor and 10 nF RC filter at the ADC input, as recommended in Infineon Design Tip DT97-3.
How does the ITRIP blanking time interact with PWM frequency?
The internal 400 ns ITRIP blanking window is fixed and independent of PWM frequency. At 20 kHz (50 µs period), blanking occupies only 0.8% of the cycle-sufficient to suppress switching noise while preserving fast over-current response. No adjustment is needed for frequencies from 1 kHz to 100 kHz.
Is the IR2135STRPBF RoHS-compliant and halogen-free?
Yes-IR2135STRPBF carries the "PbF" suffix per Infineon's part numbering convention, confirming full compliance with RoHS Directive 2011/65/EU and halogen-free material requirements (IEC 61249-2-21). Certificate of Compliance is available upon request from Aetrix Electronics' technical support team.
