Product details
Overview
IR2235JPBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with six independent gate drive channels (three high-side and three low-side), rated for up to 1200V offset voltage, ±420 mA/±200 mA output current, 750 ns/700 ns typical turn-on/turn-off propagation delay, and 250 ns matched deadtime-used in motor inverters for industrial AC drives and servo systems.
For engineers reviewing the IR2235JPBF datasheet, IR2235JPBF pinout, IR2235JPBF application, or IR2235JPBF equivalent, key selection criteria include floating channel dV/dt immunity, integrated current-sense amplifier with trip threshold (470–670 mV), independent shutdown (SD) and fault-clear (FLT-CLR) logic, and 2.5V-compatible inputs for microcontroller interfacing.
Technical Context
The IR2235JPBF integrates three isolated high-side drivers using proprietary HVIC technology, enabling operation with VS offset up to +1200 V referenced to COM while maintaining logic-level compatibility down to 2.5 V. Each high-side channel features bootstrap-capable floating supplies (VB1–VB3) and matched propagation delays (750/700 ns typ.) to minimize timing skew across phases.
It embeds a precision current-sense amplifier (CA+, CA−, CAO) with 5–10 V/µs slew rate, 50–70 dB CMRR/PSRR, and programmable over-current shutdown via external sense resistor; fault detection triggers open-drain FAULT output and disables all six outputs within 850 ns (typ.), cleared only by active-low FLT-CLR assertion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VS Offset Max | 1200 V - enables direct driving of high-side IGBTs/MOSFETs in 690 VAC industrial motor inverters without external level shifters |
| IO+ / IO− | 200 mA / 420 mA - sufficient peak current to charge/discharge 1000 pF gate capacitance in <100 ns for 20 kHz PWM switching |
| ton / toff (typ.) | 750 ns / 700 ns - ensures tight timing control for SiC/GaN-compatible gate drive with minimal shoot-through risk |
| Deadtime (typ.) | 250 ns - factory-matched internal delay prevents cross-conduction during HS-to-LS and LS-to-HS transitions |
| VCC Range | 10–20 V - supports wide-input auxiliary supply designs while maintaining undervoltage lockout (UVLO) hysteresis of 1 V |
| ITRIP Threshold | 470–670 mV - precise analog trip window allows accurate current limiting with ±1% external sense resistor |
| Logic Compatibility | 2.5 V - interfaces directly with low-voltage MCUs (e.g., ARM Cortex-M0+) without level-shifting circuitry |
Pinout & Package
IR2235JPBF is housed in a 28-lead SOIC (wide-body) package with gull-wing leads, optimized for thermal dissipation and creepage in high-voltage motor control PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN1–HIN3 | High-side input logic | Inverted-phase PWM inputs controlling HO1–HO3; 2.5V-tolerant, internally clamped to 5.2V |
| LIN1–LIN3 | Low-side input logic | Inverted-phase PWM inputs controlling LO1–LO3; same clamping and logic thresholds as HIN |
| HO1–HO3 | High-side gate drive outputs | Floating outputs referenced to VS1–VS3; capable of sourcing 200 mA/sinking 420 mA into gate loads |
| LO1–LO3 | Low-side gate drive outputs | Ground-referenced outputs; matched timing with HO channels for synchronous 3-phase commutation |
| VB1–VB3 | High-side floating supply | Bootstrap capacitor connection points; rated for 1225 V max, supporting 1200 V VS offset operation |
| VS1–VS3 | High-side floating return | Source nodes for high-side power devices; withstands −5 V to +1200 V transients relative to COM |
| VCC | Fixed logic supply | Powers internal logic, low-side drivers, and amplifier; UVLO threshold 9.2–11.6 V (positive-going) |
| COM | Low-side power return | Common reference for LO outputs and current-sense amplifier; must be tied to system power ground |
| CA+, CA−, CAO | Current-sense amplifier I/O | Differential inputs (CA+/CA−) and single-ended output (CAO); enables real-time phase current monitoring and fast OCP |
| ITRIP | Over-current trip input | Analog input accepting amplified sense voltage; triggers full shutdown if >670 mV (typ.) |
| SD | Shutdown control | Active-high input disabling all six outputs within 750 ns; overrides PWM inputs during fault recovery |
| FLT-CLR | Fault clear input | Active-low input resetting FAULT latch and re-enabling outputs after over-current or UVLO event |
| FAULT | Fault status output | Open-drain signal pulled low during UVLO or over-current; requires external pull-up for system-level fault signaling |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables bootstrap-based high-side drive up to 1200 V without external isolators or level shifters |
| Matched propagation delay | Ensures ≤50 ns skew between HO/LO channels across temperature (−40°C to +125°C) and supply voltage (10–20 V) |
| Integrated current-sense amplifier | Provides 70 dB CMRR and 10 V/µs positive slew rate for accurate, noise-immune phase current feedback |
| Independent UVLO per supply | Separate 1 V hysteresis on VCC and VBx supplies prevents erratic operation during brown-out or bootstrap capacitor droop |
| Programmable blanking time | 400 ns internal ITRIP blanking window suppresses false trips during switching transients at high dV/dt |

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 |
|---|---|---|---|
| IR2233JPBF | 600 V VS offset rating; identical pinout, timing, and feature set except lower high-side voltage capability | Suitable for 400 VAC systems (e.g., HVAC fans, small pumps) but not 690 VAC industrial motors or 800 V EV systems | Select when cost sensitivity outweighs 1200 V margin and system bus voltage remains ≤600 V |
| IRS2330JPbF | Single 3-phase driver with integrated bootstrap diodes; lacks current-sense amplifier and ITRIP input | Targeted at cost-optimized inverters where external current sensing is acceptable and fault response time >2 µs is tolerable | Choose for simplified BOM in non-safety-critical applications where CA amplifier functionality is unnecessary |
Compared with IR2233JPBF and IRS2330JPbF, the IR2235JPBF uniquely combines 1200 V robustness, integrated current sensing, and sub-microsecond fault response-making it the only option qualified for SIL-2-compliant industrial drives and high-voltage EV charging topologies.

FAQ
What is the maximum allowable dV/dt at the VS pins?
The IR2235JPBF is rated for 50 V/ns dV/dt at the VS1–VS3 pins under all operating conditions. This specification ensures reliable operation during fast-switching events in IGBT and SiC-based inverters without false triggering or latch-up, validated across temperature (−40°C to +125°C) and supply voltage (10–20 V).
Can the current-sense amplifier be used for closed-loop motor control?
Yes-the CA+ and CA− inputs accept differential signals from a shunt resistor, and CAO provides a rail-to-rail output with 10 V/µs slew rate and 70 dB CMRR. It supports real-time current sampling at up to 20 kHz, enabling field-oriented control (FOC) loops when paired with a 12-bit ADC and appropriate filtering.
How does the FLT-CLR function interact with the SD pin?
FLT-CLR is an asynchronous, active-low input that clears the FAULT latch and restores normal operation only after both over-current and UVLO faults have been resolved. The SD pin remains fully functional during fault conditions and can force immediate shutdown regardless of FLT-CLR state-providing layered safety control.
Is external bootstrap diode required for VB1–VB3 connections?
No-internal bootstrap diodes are integrated into the IR2235JPBF. However, external fast-recovery diodes (e.g., 1N4148W) are recommended for improved reliability in high-temperature or high-frequency (>20 kHz) applications to reduce reverse recovery losses and ensure consistent VBS charging.
