Infineon Technologies IR2233J

Overview

IR2233J 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 capability, 750 ns/700 ns typical turn-on/turn-off propagation delay, and 250 ns matched deadtime - used in motor inverters, industrial AC drives, and UPS systems.

For engineers reviewing the IR2233J datasheet, IR2233J pinout, IR2233J application, or IR2233J equivalent, key selection considerations include its 1200V floating channel rating, integrated current-sense amplifier with ITRIP threshold (470–670 mV), fault-clear logic (FLT-CLR), and undervoltage lockout on both VCC and VB supplies.

Technical Context

The IR2233J integrates three independent half-bridge drivers using HVIC technology, enabling robust bootstrap operation at up to +1200V VS offset. Each high-side channel features matched propagation delay (750/700 ns) and dV/dt immunity, while logic inputs support 2.5V CMOS/LSTTL compatibility.

An internal operational amplifier provides analog current feedback via external sense resistor, with programmable over-current shutdown (ITRIP input, 470–670 mV threshold) and blanking time (~400 ns). Fault status is signaled via open-drain FAULT output, cleared by active-low FLT-CLR.

FAQ

What is the maximum allowable dV/dt on the VS pins of the IR2233J?

The IR2233J is specified as dV/dt immune up to 50 V/ns on its high-side floating supply returns (VS1–VS3), verified per manufacturer test conditions. This rating ensures reliable operation during fast-switching events in IGBT or SiC-based inverters without false triggering of the high-side logic. The internal level-shifting circuitry maintains correct state even under rapid common-mode transients.

Can the IR2233J drive both IGBTs and MOSFETs?

Yes - the IR2233J supports gate drive for both N-channel IGBTs and MOSFETs, with output current ratings of ±200 mA (source) and ±420 mA (sink), and adjustable VOUT range (12–20 V). Its 1200 V VS offset rating and 250 ns deadtime make it suitable for 650 V and 1200 V IGBT modules, while its fast propagation delay (750/700 ns) also accommodates high-frequency Si-MOSFET or SiC-MOSFET switching.

How does the ITRIP over-current protection function?

The ITRIP input monitors voltage across an external current-sense resistor. When this voltage exceeds 470–670 mV (typ.), the device initiates shutdown of all six outputs within 850 ns. A 400 ns blanking window suppresses false trips during switching transitions. The FAULT pin goes low and remains latched until cleared by a low pulse on FLT-CLR, enabling controlled system recovery.

Is the CA amplifier in the IR2233J rail-to-rail capable?

Yes - the integrated current amplifier has rail-to-rail output swing (VSS to VCC), delivering 0–5 V output for a 0–5 V differential input range at CA+/CA−. It features 70 dB CMRR and 4 nA input bias current, enabling accurate, low-noise analog current feedback without external signal conditioning components.
