Infineon Technologies IR2233JTRPBF

Overview

IR2233JTRPBF 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, 750 ns/700 ns typical turn-on/turn-off propagation delay, and 250 ns typical deadtime-used in industrial motor inverters driving IGBTs or MOSFETs in HVAC compressors and servo drives.

For engineers reviewing the IR2233JTRPBF datasheet, IR2233JTRPBF pinout, IR2233JTRPBF application, or IR2233JTRPBF equivalent, key selection criteria include floating channel dV/dt immunity, integrated current-sense amplifier with trip threshold (470–670 mV), undervoltage lockout per supply rail, fault-clear logic input, and bootstrap-compatible high-side operation up to 1200 V.

Technical Context

The IR2233JTRPBF implements three independent half-bridge drivers using proprietary HVIC technology, enabling monolithic high-side floating operation up to +1200 V referenced to COM. Each channel features matched propagation delays (750 ns on / 700 ns off) and built-in deadtime generation (250 ns typ.) to prevent shoot-through in 3-phase PWM systems.

It integrates an analog 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; recovery requires active FLT-CLR assertion.

Key Specifications

FAQ

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

The IR2233JTRPBF is rated for 50 V/ns dV/dt immunity at the VS1–VS3 pins, verified per datasheet test conditions. This specification ensures reliable operation during fast-switching transitions in 1200 V bus applications, including those using SiC or fast IGBTs. Exceeding this rate may cause false triggering of the high-side level shifter or latch-up.

Can the CAO output drive a microcontroller ADC directly?

Yes-the CAO output provides a rail-to-rail analog voltage (0–5.4 V) with ±20 mV low-level output and 4–7 mA source capability, compatible with most 12-bit microcontroller ADCs. For optimal accuracy, use a 10 kΩ series resistor and 100 nF bypass capacitor at the ADC input to filter switching noise without degrading bandwidth.

How does the internal ITRIP blanking time interact with external filtering?

The IR2233JTRPBF applies a fixed 400 ns internal blanking window after each PWM edge, independent of external RC filters. External filtering on the ITRIP pin should be minimized-only enough to suppress EMI (e.g., 100 Ω + 100 pF)-as excessive delay risks missing valid over-current events during the unblanked portion of the cycle.

Is the FAULT pin actively driven or open-drain?

The FAULT pin is strictly open-drain with no internal pull-up. It sinks up to 100 µA when asserted (low) and presents high-impedance when inactive. An external pull-up resistor (typically 4.7–10 kΩ to VCC or 3.3 V) is mandatory to generate a valid logic-high signal for microcontroller interrupt inputs or status LEDs.
