Infineon Technologies IR2233SPBF

Overview

IR2233SPBF from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with six-channel gate drive (three independent half-bridges), 1200 V high-side offset rating, ±420 mA low-side/±200 mA high-side peak output current, 750/700 ns typical turn-on/turn-off propagation delay, and integrated current-sense amplifier for over-current protection - used in industrial motor inverters and servo drives.

For engineers reviewing the IR2233SPBF datasheet, IR2233SPBF pinout, IR2233SPBF application, or IR2233SPBF equivalent, key selection criteria include high-side floating voltage capability (1200 V), matched propagation delays across all channels, undervoltage lockout per supply rail, fault-clear functionality, and analog current feedback via CA+/CA−/CAO pins.

Technical Context

The IR2233SPBF integrates three independent high-side and low-side drivers using HVIC technology, enabling operation with VS up to +1200 V relative to COM while maintaining logic compatibility down to 2.5 V. Each channel features matched propagation delay (750 ns typ. ton / 700 ns typ. toff) and programmable deadtime (250 ns typ.) to prevent shoot-through in 3-phase inverter topologies.

It includes an internal operational amplifier (CA+, CA−, CAO) with 5–10 V/µs slew rate and ±30 mV input offset, supporting real-time bridge current monitoring via external sense resistor. Over-current shutdown is triggered by ITRIP input with 400 ns blanking time and 650 ns fault-to-FAULT signal propagation.

Key Specifications

FAQ

What is the maximum allowable dV/dt at the VS pins?

The IR2233SPBF is rated for 50 V/ns dV/dt immunity at the VS pins, verified per Absolute Maximum Ratings table. This tolerance enables reliable operation in fast-switching SiC or GaN-based inverters where high dv/dt transients occur during commutation, without false triggering of high-side logic.

Can the CAO output drive a comparator directly?

Yes - the CAO output has rail-to-rail capability (0–5.4 V) and can source up to 7 mA, allowing direct connection to standard comparators like LM393 without buffering. Its 5–10 V/µs slew rate supports accurate sampling of current peaks up to 100 kHz switching frequencies.

Is the FLT-CLR function latched or edge-triggered?

The FLT-CLR input is active-low and edge-triggered on the falling edge: a brief LOW pulse (≥100 ns) clears the FAULT latch and restores normal operation. It does not require sustained LOW state - enabling clean reset via MCU GPIO without holding the line low.

Does the IR2233SPBF support 3.3 V logic inputs without level shifting?

Yes - with VIH = 2.2 V min and VIL = 0.8 V max, the IR2233SPBF fully supports 3.3 V CMOS logic levels. Input bias current is ≤350 µA at 0 V and ≤250 µA at 5 V, ensuring compatibility with low-drive-strength microcontrollers such as STM32 or C2000 series.
