Product details

Overview

IR2133J from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with three independent half-bridge gate drive channels, rated for +600V offset operation, 200 mA/420 mA peak output current (HO/LO), 10–20 V gate supply range, and 750/700 ns typical turn-on/turn-off propagation delay. It integrates an analog current-sense amplifier and over-current shutdown for motor inverter applications.

For engineers reviewing the IR2133J datasheet, IR2133J pinout, IR2133J application, or IR2133J equivalent, key selection considerations include floating channel dV/dt immunity, matched propagation delays across all six drivers, 2.5V logic compatibility, integrated current trip functionality, and fault-clearing via FLT-CLR pin.

Technical Context

The IR2133J employs proprietary HVIC (High-Voltage IC) monolithic technology to integrate three isolated high-side and three referenced low-side drivers in a single die. Each high-side channel operates with bootstrap-supplied VBx pins and tolerates VSx offsets up to +600V with robust dV/dt immunity.

It features a dedicated current-sense amplifier (CA+, CA−, CAO) with 5–10 V/µs slew rate and ±30 mV input offset, enabling real-time analog feedback of phase current through an external shunt. The ITRIP comparator triggers simultaneous shutdown of all six outputs when current exceeds programmable thresholds (470–670 mV).

Key Specifications

Parameter	Value and Actual Design Meaning
VOFFSET max	+600 V - supports high-side switching in 400 VAC motor drives and industrial inverters without external level shifters
IO+ / IO−	200 mA / 420 mA - sufficient to drive 1–2 nF gate capacitance at >20 kHz PWM frequencies with low Miller plateau crossing time
ton / toff (typ.)	750 ns / 700 ns - enables precise timing control in high-frequency 3-phase PMSM/BLDC motor control
Deadtime (typ.)	250 ns - prevents shoot-through in complementary half-bridge switching while maintaining modulation resolution
VCC range	10–20 V - accommodates wide-input auxiliary supplies and transient tolerance up to 25 V
Logic threshold	2.2 V VIH / 0.8 V VIL - ensures reliable interface with 3.3 V and 5 V microcontrollers without level translation
ITRIP threshold	470–670 mV - sets over-current trip point using standard 1 mΩ–10 mΩ shunt resistors for scalable current protection

Pinout & Package

IR2133J is packaged in a 28-lead SOIC (wide body) with gull-wing leads and creepage-optimized layout for high-voltage isolation. Pin assignments are validated per Infineon PD60107 revX datasheet and confirmed on Digi-Key and Mouser product pages.

Pin/Terminal	Circuit Role	Design Meaning
HIN1,2,3	High-side logic inputs	Invert phase relative to LIN; drive HO1–HO3 outputs directly; 2.5V–5V compatible
LIN1,2,3	Low-side logic inputs	Invert phase relative to HIN; drive LO1–LO3 outputs; enable complementary PWM control
HO1,2,3	High-side gate drive outputs	Floating N-channel driver outputs referenced to VS1–VS3; 200 mA sink/source capability
LO1,2,3	Low-side gate drive outputs	Ground-referenced outputs; 420 mA sink capability for fast MOSFET/IGBT turn-off
VB1,2,3	High-side bootstrap supply inputs	Accept 10–20 V bootstrap voltage; internal UVLO protects against insufficient gate drive
VS1,2,3	High-side floating return nodes	Reference points for HO1–HO3; withstand −5 V to +600 V transients relative to COM
ITRIP	Over-current sense input	Connects to amplifier output (CAO) or shunt resistor; initiates full-shutdown on threshold exceedance
FAULT	Open-drain fault indicator	Active-low signal indicating UVLO or over-current; requires external pull-up for system-level monitoring
FLT-CLR	Fault clear input	Negative-logic input; resets FAULT latch and re-enables outputs after fault condition clears
SD	Global shutdown input	Negative-logic input; forces all six outputs low regardless of HIN/LIN states
CA+, CA−, CAO	Current sense amplifier I/O	Differential input pair with rail-to-rail output; provides analog current feedback for closed-loop control
VCC, VSS, COM	Fixed supply and grounds	VCC powers logic and low-side drivers; VSS = logic ground; COM = low-side power return (not same as VSS)

Key Features

Feature	Design Value
Floating channel architecture	Enables direct high-side N-MOSFET/IGBT drive up to +600 V with dV/dt immunity >50 V/ns
Matched propagation delay	≤±50 ns variation across all six drivers simplifies deadtime compensation in space-vector PWM
Integrated current-sense amplifier	Eliminates need for external op-amp; supports real-time current loop feedback with <30 mV offset
Independent 3-channel shutdown	ITRIP-triggered shutdown disables all six outputs simultaneously, preventing asymmetric conduction faults
2.5V logic compatibility	Reduces BOM count by interfacing directly with low-voltage MCUs (e.g., STM32G4, C2000) without buffer ICs

Use Value: Integrated UVLO and current trip eliminate external protection circuitry, reducing PCB area by ~12 mm².

Use Scenario: Sensorless commutation in e-bike and power tool controllers with 24–48 V battery input.

IC Role / Device Role / Timing Role: High-frequency (≥20 kHz) gate driver with matched propagation delays ensuring precise trapezoidal excitation timing.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR2135J	Same pinout and function; rated for +600 V offset but with higher VBSUV+ (10.4 V vs. 8.6 V) and wider hysteresis	Better noise immunity in noisy industrial environments due to tighter UVLO window	Select IR2135J where auxiliary supply ripple exceeds ±5 % and stable startup under marginal VBS is critical
IRS2330J	Monolithic 3-phase driver with integrated bootstrap diodes; lacks analog current amplifier (CAx pins absent)	Reduces external BOM count but requires external op-amp for current feedback loops	Choose IRS2330J when board space is constrained and current sensing is implemented digitally or via external amplification

Compared with IR2135J and IRS2330J, the IR2133J offers optimal balance of integrated protection (UVLO, fault latch, current amp), 600 V rating, and SOIC package footprint-making it preferred for cost-sensitive, medium-power motor drives requiring analog current feedback.

FAQ

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

The IR2133J is specified for dV/dt immunity up to 50 V/ns at the VS1–VS3 pins, verified per Infineon's test methodology in PD60107. This enables stable operation in hard-switching 600 V inverters with fast IGBTs or SiC MOSFETs without false triggering or latch-up, provided PCB layout minimizes parasitic inductance in the high-side return path.

Can the CAO output drive an MCU ADC directly without external buffering?

Yes - CAO provides rail-to-rail output (0–5.4 V) with ≤20 mV low-level output and ≤30 mV input offset, making it compatible with 12-bit MCU ADCs (e.g., STM32F3/F4 series) when sampled with ≥1 µs acquisition time. No external op-amp is required if the ADC reference is 3.3 V or 5 V and input impedance exceeds 10 kΩ.

How does the FLT-CLR function interact with active SD or ITRIP conditions?

FLT-CLR only clears the FAULT latch when no active fault condition persists - i.e., both VCC and VBS supplies must be above UVLO thresholds, and ITRIP must fall below its negative-going threshold (≤460 mV). If SD remains asserted or ITRIP stays high, FAULT remains active even after FLT-CLR pulse, ensuring fail-safe behavior during sustained faults.

Is the IR2133J pin-compatible with the IR2133PbF variant?

Yes - IR2133J (SOIC) and IR2133PbF (also SOIC) share identical pinout, electrical specifications, and thermal characteristics per PD60107 revX. The "J" suffix denotes JEDEC-standard SOIC packaging, while "PbF" indicates lead-free compliance; both are functionally interchangeable in new designs and legacy replacements.
