Infineon Technologies IR2233JTR

Overview

IR2233JTR from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with six-channel gate drive capability (three independent half-bridges), 1200 V high-side offset rating, ±420 mA/±200 mA 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 UPS systems.

For engineers reviewing the IR2233JTR datasheet, IR2233JTR pinout, IR2233JTR application, or IR2233JTR equivalent, key selection criteria include high-side floating voltage tolerance (1200 V), matched propagation delays across all channels, undervoltage lockout per supply rail, fault-clear functionality, and analog current feedback via CA+/CA− inputs.

Technical Context

The IR2233JTR integrates three independent high-side and low-side drivers using HVIC technology, enabling robust bootstrap operation up to 1200 V VS offset. Each channel features matched propagation delay (750 ns ton / 700 ns toff) and programmable deadtime (250 ns typ.) to prevent shoot-through in 3-phase inverter legs.

It includes a dedicated operational amplifier (CA+, CA−, CAO) with 5–10 V/µs slew rate and 50–70 dB CMRR/PSRR for real-time bridge current sensing, plus logic-compatible inputs (2.5 V min. VIH), independent shutdown (SD), and open-drain FAULT output with FLT-CLR recovery.

Key Specifications

Pinout & Package

Equivalent & Alternatives

The following parts are listed as comparable options for similar 3-phase high-voltage gate driver applications.

Compared with IR2235JTR, the IR2233JTR provides more aggressive UVLO hysteresis (0.4 V) for stable operation near threshold, while IRS2330JPbF lacks both 1200 V rating and current-sense amplifier - limiting it to simpler, lower-voltage motor drives.

FAQ

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

The IR2233JTR is rated for 50 V/ns maximum dV/dt at VS1–VS3 pins under normal operating conditions. This specification ensures immunity to fast transient voltage spikes common in IGBT-based inverters, preventing false triggering or latch-up in the floating channel circuitry. Exceeding this limit may cause timing skew or temporary loss of high-side drive capability.

Can the CA amplifier be used for bidirectional current sensing?

Yes - the CA+ and CA− inputs accept differential voltages from ±5 V, and CAO delivers a 0–5 V output proportional to (CA+ − CA−). With appropriate external resistor scaling and biasing, it supports bidirectional shunt-based current measurement in regenerative braking or V2G applications, provided common-mode voltage remains within VSS to VCC.

Is bootstrap capacitor sizing dependent on switching frequency?

Yes - required bootstrap capacitance increases with higher switching frequency and gate charge (Qg) of driven IGBTs/MOSFETs. For 20 kHz operation with 100 nC Qg devices, ≥0.22 µF ceramic + 10 µF electrolytic is recommended. Insufficient capacitance causes VBS droop, triggering UVLO and disabling high-side outputs.

Does the FAULT pin require an external pull-up resistor?

Yes - FAULT is an open-drain output and must be pulled up to a logic-compatible voltage (e.g., 3.3 V or 5 V) via an external resistor (typically 4.7–10 kΩ). Without pull-up, the pin remains floating during normal operation and cannot assert a valid low-level fault signal to the host controller.
