Product details

Overview

IR2233PBF 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 output sink/source 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 IR2233PBF datasheet, IR2233PBF pinout, IR2233PBF application, or IR2233PBF 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 via FLT-CLR, and analog current feedback capability through CA+/CA-/CAO pins.

Technical Context

The IR2233PBF integrates three independent high-side and low-side drivers using HVIC technology, enabling operation with VS up to +1200 V relative to COM while maintaining logic compatibility down to 2.5 V. Each channel features matched propagation delay (750/700 ns typ.) and built-in deadtime (250 ns typ.) to prevent shoot-through in 3-phase inverter legs.

A dedicated operational amplifier (CA+, CA−, CAO) provides real-time analog current sensing via external shunt resistor, with programmable over-current shutdown (ITRIP threshold 470–670 mV) and blanking time (400 ns). Fault status is reported via open-drain FAULT output, cleared only by active-low FLT-CLR signal.

Key Specifications

Parameter	Value and Actual Design Meaning
High-side offset voltage	1200 V max - enables direct driving of N-channel IGBTs/MOSFETs in high-voltage 3-phase inverter topologies up to 1200 V DC bus.
Output drive current	+200 mA / −420 mA - sufficient to rapidly charge/discharge gate capacitance of power devices in high-frequency PWM applications.
Propagation delay (ton/toff)	750 / 700 ns typ. - tightly matched across all six channels for precise timing control in synchronous 3-phase switching.
Deadtime	250 ns typ. - hardware-enforced minimum interval between high-side turn-on and low-side turn-off to eliminate cross-conduction.
VCC & VB supply range	10–20 V (VCC), 12–20 V (VB) - supports flexible bootstrap and fixed-supply configurations with transient tolerance up to 25 V.
Current sense amplifier	Input offset ≤30 mV, CMRR ≥70 dB - delivers accurate analog current feedback for closed-loop motor control and fast over-current response.
Logic input threshold	2.2 V (VIH), 0.8 V (VIL) - compatible with 2.5 V, 3.3 V, and 5 V CMOS/LSTTL controllers without level-shifting.

Pinout & Package

IR2233PBF is housed in a 28-lead SOIC (wide-body) package with gull-wing leads, optimized for thermal performance and high-voltage isolation in motor drive PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
HIN1, HIN2, HIN3	High-side logic inputs	Invert phase relative to HO outputs; accept 2.5–5 V logic; enable independent PWM control per phase.
LIN1, LIN2, LIN3	Low-side logic inputs	Invert phase relative to LO outputs; synchronized with HIN for complementary half-bridge drive.
HO1–HO3	High-side gate drive outputs	Floating outputs referenced to VS1–VS3; drive gates of high-side N-channel devices in bootstrap configuration.
LO1–LO3	Low-side gate drive outputs	Ground-referenced outputs; sink/source up to 420 mA/200 mA to switch low-side power devices.
VB1–VB3	High-side floating supply inputs	Connect to bootstrap capacitors; support 12–20 V supply for high-side drivers operating at VS up to +1200 V.
VS1–VS3	High-side floating supply returns	Reference nodes for high-side drivers; tolerate −5 V to +1200 V transients relative to COM.
ITRIP	Over-current trip input	Analog input monitoring shunt voltage; triggers shutdown when >470–670 mV (hysteresis enabled).
CA+, CA−, CAO	Current amplifier terminals	Differential input (CA+/CA−) and single-ended output (CAO) for precision analog current feedback path.
FAULT	Open-drain fault indicator	Active-low signal asserting on UVLO or over-current; requires external pull-up for system-level fault detection.
FLT-CLR	Fault clear input	Active-low asynchronous reset; clears FAULT latch and re-enables outputs after fault condition is removed.
SD	Shutdown input	Active-high global disable; forces all HO/LO outputs low and asserts FAULT until cleared.
VCC	Fixed logic supply	10–20 V input powering internal logic, low-side drivers, and amplifier; includes UVLO (7.2–9.6 V thresholds).
VSS	Logic ground reference	Return for VCC, inputs, and amplifier; isolated from COM to maintain noise immunity in mixed-signal operation.
COM	Low-side power return	Common return for LO outputs and current-sense amplifier; connects to system power ground or shunt resistor low side.

Key Features

Feature	Design Value
Floating channel architecture	Supports +1200 V high-side operation with dV/dt immunity - eliminates need for external level-shifters in high-voltage inverter designs.
Matched propagation delay	≤50 ns inter-channel skew (750/700 ns typ.) - ensures consistent timing across all three phases for balanced torque and reduced EMI.
Integrated current-sense amplifier	DC-coupled, rail-to-rail output (0–5.4 V), 70 dB CMRR - enables accurate real-time motor phase current measurement without external op-amps.
Independent UVLO per supply	Separate thresholds for VCC (7.2–9.6 V) and VB (7.2–9.6 V or 8.3–10.5 V depending on variant) - prevents erratic switching during brown-out conditions.
Programmable over-current shutdown	ITRIP input with 400 ns blanking window - rejects switching noise while responding to true over-current events within <1 µs.

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
IR2235PBF	Higher VBS UVLO threshold (9.2–11.6 V vs. 7.2–9.6 V); identical pinout and functionality.	Better suited for systems with tighter VBS regulation or higher ambient temperature operation where lower UVLO hysteresis improves stability.	Select IR2235PBF when VBS supply ripple exceeds ±0.5 V or junction temperature routinely exceeds 100 °C.
IRS2330JPbF	Single 8-pin SOIC package; integrates bootstrap diodes; lacks current-sense amplifier and ITRIP input.	Targeted at cost-sensitive, lower-power (<2 kW) inverters where external current sensing is acceptable.	Choose IRS2330JPbF only if analog current feedback is not required and board space constraints favor smaller footprint.

Compared with IR2233PBF, IR2235PBF offers enhanced supply noise immunity at the expense of slightly reduced low-VB margin, while IRS2330JPbF trades integrated protection features for compactness and lower cost - making IR2233PBF optimal for mid-to-high-power industrial drives requiring full analog current monitoring and robust fault management.

FAQ

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

The IR2233PBF is rated for up to 50 V/ns dV/dt on VS1–VS3 pins under normal operating conditions. This specification ensures immunity to fast voltage transients common in IGBT-based inverters. Exceeding this rate may cause false triggering of high-side logic or latch-up; layout best practices (short traces, local decoupling, ground plane separation) are essential to maintain margin.

Can the CA amplifier be used for both over-current protection and closed-loop current control?

Yes - the CA amplifier (CA+, CA−, CAO) provides a buffered, low-offset analog output directly proportional to shunt voltage, usable for real-time current loop control in field-oriented control (FOC) algorithms. Its 70 dB CMRR and 5–10 V/µs slew rate support bandwidths up to ~100 kHz, while the dedicated ITRIP comparator enables fast (<1 µs) hardware-level over-current shutdown independent of MCU intervention.

Is IR2233PBF pin-compatible with IR2133PBF?

No - although functionally similar, IR2233PBF and IR2133PBF differ in high-side voltage rating (1200 V vs. 600 V), UVLO thresholds, and absolute maximum ratings. Their pinouts are identical in 28-lead SOIC, but substituting one for the other without verifying voltage stress margins, bootstrap capacitor sizing, and supply sequencing risks catastrophic failure in 1200 V applications.

How does the FLT-CLR function interact with SD and ITRIP signals?

FLT-CLR is an asynchronous, active-low input that resets the internal fault latch regardless of ongoing SD assertion or ITRIP state. However, if SD remains high or ITRIP stays above threshold after FLT-CLR deassertion, the FAULT output will immediately reassert. True recovery requires removal of the root cause (e.g., clearing over-current condition or restoring VCC/VB supply) before issuing FLT-CLR.
