Infineon Technologies IR2233JPBF

Overview

IR2233JPBF 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 1200 V offset voltage, ±200 mA / +420 mA output current, 10–20 V gate supply range, 750/700 ns typical turn-on/turn-off propagation delay, and 250 ns matched deadtime. It integrates an analog current-sense amplifier and over-current shutdown for motor inverter applications.

For engineers reviewing the IR2233JPBF datasheet, IR2233JPBF pinout, IR2233JPBF application, or IR2233JPBF equivalent, key selection criteria include floating channel robustness at 1200 V, matched propagation delays across all six drivers, integrated current-sense amplifier with 5–10 V/µs slew rate, and fault-clear functionality via FLT-CLR pin.

Technical Context

The IR2233JPBF employs proprietary HVIC technology to enable monolithic high-side floating channel operation up to 1200 V VS offset, with dV/dt immunity and negative transient tolerance. Its logic inputs are 2.5 V compatible and out-of-phase with outputs, supporting direct connection to microcontroller PWM outputs.

All three half-bridge drivers feature matched propagation delays (750/700 ns typ.), programmable deadtime (250 ns typ.), and independent undervoltage lockout on both VCC and VBx supplies. The integrated current amplifier provides analog feedback via external sense resistor, with dedicated ITRIP input triggering simultaneous shutdown of all six outputs.

FAQ

What is the maximum allowable dV/dt at VS1,2,3 for reliable operation?

The IR2233JPBF is specified for 50 V/ns dV/dt immunity on all high-side floating supply returns (VS1–VS3). This rating is verified per Infineon PD60107 revX test conditions and ensures robust operation during fast-switching transitions in 1200 V IGBT or SiC MOSFET half-bridges without false triggering or latch-up.

Can the CAO output drive a microcontroller ADC directly?

Yes - CAO provides rail-to-rail analog output (0–5.4 V) with ±20 mV low-level output and 4–7 mA source/sink capability. When interfaced with a 10-bit or higher ADC and appropriate RC filtering (e.g., 10 kΩ + 1 nF), it delivers accurate digitized current measurements without external buffering.

How does the ITRIP blanking time prevent false over-current trips?

The IR2233JPBF applies a fixed 400 ns blanking window after each HIN/LIN edge transition, during which the ITRIP comparator is disabled. This eliminates false triggering from switching-induced voltage spikes across the current sense resistor, ensuring only sustained over-current events initiate shutdown.

Is the FLT-CLR function asynchronous or synchronized to the internal clock?

FLT-CLR is fully asynchronous - asserting the pin low immediately resets the internal fault latch regardless of PWM timing or clock phase. This enables deterministic fault recovery in safety-critical applications, such as emergency stop sequences in industrial motion control systems.
