Product details

Overview

IR2233S from Infineon Technologies is a high-voltage, high-speed 3-phase bridge driver IC with six independent gate drive outputs (three high-side and three low-side), rated for up to 1200V offset voltage, ±420 mA/±200 mA output current, 750/700 ns typical turn-on/turn-off propagation delay, and 250 ns typical deadtime. It integrates an analog current-sense amplifier and over-current shutdown for motor inverter applications.

For engineers reviewing the IR2233S datasheet, IR2233S pinout, IR2233S application, or IR2233S equivalent, key selection criteria include floating channel operation at 1200V, matched propagation delays across all channels, 2.5V logic compatibility, integrated current trip function, and fault-clear capability via FLT-CLR pin.

Technical Context

The IR2233S employs proprietary HVIC technology to enable monolithic high-side floating channel operation up to 1200V VS offset, with dV/dt immunity and negative transient tolerance. Its three half-bridge drivers feature matched propagation delays (750/700 ns typ.) and programmable deadtime (250 ns typ.), supporting high-frequency PWM control in 3-phase inverters.

An integrated operational amplifier provides analog current feedback via external sense resistor, with 5–10 V/µs slew rate and 50–70 dB CMRR/PSRR. Over-current shutdown triggers within 850 ns (typ.) and asserts open-drain FAULT signal, cleared only by active-low FLT-CLR input.

Key Specifications

Parameter	Value and Actual Design Meaning
VS Offset Max	1200 V - supports high-side IGBT/MOSFET switching in industrial 600–1000V DC bus systems
IO+ / IO−	200 mA / 420 mA - drives gate capacitance of medium-power IGBTs (e.g., 30–60 A, 1200V) without external buffers
VOUT Range	12–20 V - configurable gate drive voltage enabling optimized switching loss vs. robustness trade-off
ton / toff (typ.)	750 / 700 ns - enables >200 kHz PWM operation with precise timing control
Deadtime (typ.)	250 ns - prevents shoot-through in 3-phase bridge while maintaining modulation resolution
Logic Threshold	2.2 V VIH / 0.8 V VIL - compatible with 2.5V, 3.3V, and 5V microcontrollers without level-shifting
Amplifier Slew Rate	5–10 V/µs (SR+) - supports fast current sensing for cycle-by-cycle over-current protection

Pinout & Package

IR2233S is housed in a 28-lead SOIC (wide body) package with gull-wing leads, designed for surface-mount assembly and thermal reliability in motor drive PCBs.

Pin/Terminal	Circuit Role	Design Meaning

HO1,2,3	High-side gate output	Floating N-channel driver outputs referenced to VS1–VS3; capable of sourcing 200 mA peak
LO1,2,3	Low-side gate output	Ground-referenced outputs sinking 420 mA peak; drive low-side switches directly
VB1,2,3	Floating supply input	Bootstrap or isolated supply inputs for high-side drivers; each supports 12–20 V
VS1,2,3	Floating return	High-side source nodes tied to respective power device sources; define local ground for VB/HO
ITRIP	Current sense comparator input	Accepts voltage from external shunt resistor; triggers shutdown when ≥570 mV (typ.)
CA+, CA−, CAO	Current amplifier terminals	Differential input (CA+/CA−) and buffered output (CAO) for analog current monitoring
FAULT	Open-drain fault indicator	Active-low signal indicating UVLO or over-current; requires external pull-up
FLT-CLR	Fault clear input	Active-low asynchronous reset for FAULT latch; must be held low ≥850 ns to clear
SD	Global shutdown input	Active-high input disabling all six outputs immediately; overrides PWM inputs
VCC	Logic supply	10–20 V input powering logic core, low-side drivers, and amplifier; separate from VB supplies
VSS	Logic ground	Reference for all logic inputs and amplifier; isolated from COM and VS nodes
COM	Low-side return	Power ground reference for LO outputs and internal current sense circuitry

Key Features

Feature	Design Value
Floating channel architecture	Enables direct high-side drive of N-channel devices up to 1200V VS offset without external level shifters
Matched propagation delay	750/700 ns (typ.) across all six channels ensures synchronized switching and minimizes phase skew in 3-phase PWM
Integrated current sense amplifier	Provides rail-to-rail output (0–5 V) with 30 mV max offset, enabling accurate real-time motor phase current measurement
Programmable over-current shutdown	ITRIP threshold fixed at 470–670 mV (typ.), allowing precise trip point setting via shunt resistor value
Asynchronous fault clear	FLT-CLR pin clears latched FAULT state independently of PWM timing, supporting safe restart after fault recovery

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR2235S	Higher VCC UVLO threshold (10.4 V typ. vs. 8.6 V); same 1200V rating and pinout	Preferred in systems with noisy 15V logic rails where tighter UVLO hysteresis improves noise immunity	Select IR2235S when VCC supply stability is marginal and higher UVLO threshold prevents false lockout
IRS2330JPbF	1200V rating, but lacks integrated current amplifier; uses external comparator for ITRIP	Suitable for cost-sensitive designs where analog current feedback is not required	Choose IRS2330JPbF when only digital over-current detection is needed and board space allows external comparator

Compared with IR2233S, IR2235S offers improved VCC undervoltage noise margin but identical timing and drive strength, while IRS2330JPbF reduces integration to lower cost at the expense of analog current monitoring capability.

FAQ

What is the maximum allowable dV/dt on the VS pins of the IR2233S?

The IR2233S is specified as dV/dt immune per its datasheet, with an absolute maximum allowable transient of 50 V/ns on VS pins. This immunity enables reliable operation in fast-switching 1200V IGBT or SiC MOSFET bridges without false triggering or latch-up, provided layout minimizes parasitic inductance in high-side return paths.

Can the CAO output drive an ADC input directly?

Yes - the CAO output is rail-to-rail (0–5 V), has low output impedance (<100 Ω), and features 20 mV max VOL and 5.4 V max VOH. It can interface directly with 12-bit or 16-bit SAR ADCs having ≥10 kΩ input impedance, though a simple RC filter (e.g., 100 Ω + 1 nF) is recommended to suppress switching noise coupling.

How does the ITRIP blanking time affect over-current response?

The IR2233S applies a 400 ns (typ.) blanking window after each PWM edge to suppress false trips from gate-drive-induced transients. During this period, ITRIP input is ignored; only sustained over-current events exceeding the blanking time trigger shutdown, ensuring robust operation during normal switching transitions.

Is the IR2233S pin-compatible with earlier IR2133S devices?

No - IR2233S is not pin-compatible with IR2133S. While both are 28-lead SOIC 3-phase drivers, IR2233S supports 1200V VS offset and includes enhanced UVLO thresholds and updated amplifier specs. Pin assignments differ for VB/VS and CAx terminals; migration requires PCB redesign and validation.
