Product details

Overview

IR2235J 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 1200V offset voltage, ±420 mA/±200 mA output current, 750 ns/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 stages in industrial AC drives.

For engineers reviewing the IR2235J datasheet, IR2235J pinout, IR2235J application, or IR2235J equivalent, key selection considerations include its 1200V floating channel capability, matched propagation delays across all six drivers, 2.5V logic compatibility, integrated current trip function, and fault-clear input for safe restart in high-reliability 3-phase power conversion systems.

Technical Context

The IR2235J implements a monolithic high-voltage IC (HVIC) architecture with three isolated floating channels, each supporting bootstrap operation up to +1200V VS offset and dV/dt immunity. Its logic inputs accept CMOS/LSTTL signals down to 2.5V, and outputs are out-of-phase with inputs to simplify PWM control.

An integrated operational amplifier provides real-time analog feedback of bridge current via an external sense resistor, while a dedicated ITRIP input triggers simultaneous shutdown of all six drivers upon over-current detection. Fault status is reported via an open-drain FAULT pin cleared by FLT-CLR.

Key Specifications

Parameter	Value and Actual Design Meaning
VS Offset Max	1200 V - Enables direct high-side driving of IGBTs/MOSFETs in 690VAC industrial motor drives without external level shifters.
IO+ / IO−	200 mA / 420 mA - Sustains fast gate charging/discharging for ≤1000 pF loads at high switching frequencies.
ton / toff (typ.)	750 ns / 700 ns - Ensures precise timing alignment across all six channels for <100 kHz PWM inverter operation.
Deadtime (typ.)	250 ns - Prevents shoot-through in complementary half-bridge pairs without external timing circuitry.
VCC Range	10–20 V - Supports wide-input auxiliary supplies and tolerates transient overvoltage up to 25 V.
Logic Threshold	2.5 V compatible - Interfaces directly with microcontrollers and DSPs without level-shifting buffers.
UVLO Hysteresis	1 V (VBS/VCC) - Provides robust supply monitoring with noise margin against false lockout during line transients.

Pinout & Package

IR2235J is housed in a 28-lead SOIC (wide body) package with gull-wing leads, optimized for thermal dissipation and creepage in high-voltage PCB layouts.

Pin/Terminal	Circuit Role	Design Meaning
HIN1,2,3	High-side logic input	Inverts input signal to drive HO1–HO3; enables synchronous 3-phase PWM with phase-shifted control.
LIN1,2,3	Low-side logic input	Direct-drive input for LO1–LO3; complements HIN for complementary half-bridge switching.
HO1,2,3	High-side gate output	Floating N-channel driver output referenced to VS1–VS3; delivers ±200 mA peak to gate capacitance.
LO1,2,3	Low-side gate output	Ground-referenced driver output delivering ±420 mA peak; supports fast turn-off of low-side switches.
VB1,2,3	High-side bootstrap supply	Connects to bootstrap capacitor per phase; powers floating driver stage up to 1200 V above COM.
VS1,2,3	High-side floating return	Reference node for VB1–VB3 and HO1–HO3; tracks switching node voltage in each half-bridge leg.
ITRIP	Over-current trip input	Analog input accepting voltage from external sense resistor; triggers full six-output shutdown when threshold exceeded.
FAULT	Open-drain fault indicator	Active-low signal indicating UVLO or over-current event; requires external pull-up for system-level fault reporting.
FLT-CLR	Fault clear input	Negative-logic input that resets FAULT latch and re-enables outputs after fault condition is removed.
CA+, CA−, CAO	Current amplifier terminals	Differential input pair and single-ended output for real-time analog current sensing and closed-loop protection.

Key Features

Feature	Design Value
Floating channel HVIC	Monolithic 1200V-rated isolation enables compact, reliable high-side gate drive without discrete level shifters.
Matched propagation delay	≤±50 ns channel-to-channel skew ensures synchronized switching across all three phases for balanced torque and low EMI.
Integrated current sense amplifier	Provides 5–10 V/µs slew rate and 70 dB CMRR for accurate analog current feedback without external op-amps.
Independent 3 half-bridge drivers	Enables full 3-phase inverter control with programmable deadtime and per-leg fault management.
2.5V logic interface	Eliminates need for level translators when interfacing with modern low-voltage MCUs and FPGAs.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR2233J	600V VS offset rating; identical pinout and feature set except lower high-side voltage tolerance.	Suitable only for 400VAC or lower motor drives; not rated for 690VAC industrial systems.	Select IR2233J where cost sensitivity outweighs 1200V requirement and system voltage remains ≤600V.
IRS2336JD	Integrated bootstrap diodes; 600V rating; no internal current amplifier; uses external op-amp for current sensing.	Lacks analog current feedback path; requires additional components for over-current protection.	Choose IRS2336JD when board space permits external sensing and 600V operation suffices.

Compared with IR2233J and IRS2336JD, the IR2235J uniquely combines 1200V capability, integrated current amplifier, and matched propagation delays-making it optimal for high-voltage industrial inverters requiring minimal external components and deterministic fault response.

FAQ

What is the maximum allowable dV/dt at the VS pins of the IR2235J?

The IR2235J is explicitly designed to be dV/dt immune, with no specified maximum limit in the datasheet. Its proprietary HVIC process and internal level-shifting architecture allow stable operation under rapid voltage transients common in IGBT-based inverters-verified up to 50 V/ns in test conditions per Absolute Maximum Ratings table.

Can the IR2235J drive SiC MOSFETs directly?

Yes-the IR2235J's 200 mA source / 420 mA sink peak output current, 750 ns/700 ns propagation delays, and 10–20 V VCC range support direct gate driving of most 650V–1200V SiC MOSFETs with ≤1000 pF total gate charge. Layout must minimize loop inductance and ensure adequate bootstrap capacitor sizing for high-frequency switching.

How does the ITRIP blanking time prevent false over-current trips?

The IR2235J incorporates a fixed 400 ns ITRIP blanking time after each PWM edge, during which the current-sense comparator is disabled. This suppresses false triggering from gate-drive-induced current spikes and parasitic ringing at switch transitions-ensuring only sustained over-current events initiate shutdown.

Is the CAO output rail-to-rail, and what is its load capability?

The CAO output is not rail-to-rail: it sources up to 7 mA and sinks up to 1 mA, with VOL ≤20 mV and VOH = 5.2 V (typ.) at VCC = 15 V. It drives standard ADC inputs or comparator thresholds directly but requires buffering for loads >10 kΩ or capacitive loads >100 pF to maintain stability and slew rate.
