Infineon Technologies IR2133JTR

Overview

IR2133JTR from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent half-bridge gate drivers (6-channel), rated for +600V floating offset voltage, 200 mA/420 mA peak output current, and 750/700 ns typical turn-on/turn-off propagation delay. It integrates undervoltage lockout, over-current shutdown, analog current-sense amplifier, and fault reporting - used in motor inverters, UPS systems, and industrial AC drives.

For engineers reviewing the IR2133JTR datasheet, IR2133JTR pinout, IR2133JTR application, or IR2133JTR equivalent, key selection considerations include bootstrap-compatible high-side operation up to 600 V, matched propagation delays across all six channels, 2.5 V logic compatibility, integrated current trip threshold (470–670 mV), and open-drain FAULT signaling with FLT-CLR recovery.

Technical Context

The IR2133JTR implements monolithic HVIC technology with three isolated floating channel drivers enabling simultaneous high-side N-channel MOSFET/IGBT control referenced to VS1–VS3. Its internal operational amplifier provides real-time analog current feedback via external sense resistor, while the ITRIP input triggers full six-output shutdown on over-current events.

Logic inputs (HIN/LIN/SD/FLT-CLR/ITRIP) are CMOS/LSTTL compatible down to 2.5 V, with internal 5.2 V zener clamping. Propagation delays (ton = 750 ns, toff = 700 ns) and deadtime (250 ns typ.) are tightly matched across all channels to minimize shoot-through risk in high-frequency PWM motor control.

Compared with IR2133JTR, IR2130JTR reduces integration (no amplifier, lower voltage rating) but lowers BOM count, while IRS2330JTRPBF trades ITRIP flexibility for integrated bootstrap diodes - both require redesign of current-sense and fault-handling circuitry.

FAQ

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

The IR2133JTR is rated for 50 V/ns dV/dt immunity at the VS1–VS3 pins, verified under test conditions per PD60107 revX. This tolerance enables reliable operation in hard-switching topologies with fast IGBT/SiC transitions without false triggering or latch-up, provided PCB layout maintains tight coupling between VS and HO traces.

Can the CAO output drive an ADC directly?

Yes - CAO provides rail-to-rail output (0–5 V) with ±20 mV low-level accuracy and 7 mA source/sink capability, making it compatible with 12-bit SAR ADCs having ≥10 kΩ input impedance. No external buffer is required if sampling occurs within amplifier's 10 µs settling time and input common-mode range (0–5 V) aligns with ADC reference.

How does the FLT-CLR function interact with active SD assertion?

FLT-CLR only clears latched fault states (UVLO or over-current) when SD is inactive (high). If SD is held low, FAULT remains asserted regardless of FLT-CLR pulses. This priority hierarchy ensures forced shutdown overrides fault recovery, supporting fail-safe system architectures where emergency stop takes precedence over fault reset.

Is IR2133JTR pin-compatible with IR2135JTR?

No - IR2133JTR and IR2135JTR share identical pinout and package but differ in undervoltage thresholds: IR2135JTR uses 9.2–11.6 V VBSUV versus 7.6–9.6 V for IR2133JTR. Swapping them risks premature UVLO in low-VCC designs or failure to trip under brown-out, requiring firmware and schematic review before substitution.
