Product details

Overview

IR2135J from Infineon Technologies (formerly International Rectifier) is a high-voltage, high-speed 3-phase bridge driver IC with independent high-side and low-side gate drive channels, 600V offset rating, 200 mA/420 mA peak output current, 750 ns/700 ns typical propagation delay, and integrated current-sense amplifier for over-current protection-used in motor inverters for industrial AC drives and servo systems.

For engineers reviewing the IR2135J datasheet, IR2135J pinout, IR2135J application, or IR2135J equivalent, key selection criteria include floating channel dV/dt immunity, matched propagation delays across all six drivers, 2.5V logic compatibility, undervoltage lockout per supply rail, and fault-clear functionality via FLT-CLR pin.

Technical Context

The IR2135J integrates three independent half-bridge drivers using HVIC monolithic technology, enabling robust operation up to +600V VS offset with dV/dt immunity. Each high-side channel uses bootstrap-supplied VBx pins referenced to VSx, while low-side outputs reference VSS/COM.

It features an internal operational amplifier with CA+, CA−, and CAO terminals for analog current feedback, plus dedicated ITRIP input for fast over-current shutdown (850 ns typical response), and open-drain FAULT output with active-low assertion on UVLO or over-current events.

Key Specifications

Parameter	Value and Actual Design Meaning
VS Offset Max	600 V - Enables direct high-side driving of N-channel MOSFETs/IGBTs in 3-phase bridges up to 400 VAC line-to-line systems.
IO+/IO−	200 mA / 420 mA - Sufficient peak gate drive current to switch 1–2 µF total gate charge at >20 kHz without external buffers.
ton/toff (typ.)	750 ns / 700 ns - Supports PWM frequencies up to 200 kHz with minimal deadtime-induced distortion.
Deadtime (typ.)	250 ns - Internally generated minimum interval prevents shoot-through during HS/LS switching transitions.
VCC Range	10–20 V - Allows use with standard 12 V or 15 V auxiliary supplies; transient tolerance to 25 V improves system robustness.
Logic Threshold	2.2 V VIH / 0.8 V VIL - Fully compatible with 2.5 V, 3.3 V, and 5 V microcontrollers without level-shifting.
UVLO Hysteresis	1.0 V - Prevents oscillation near undervoltage trip points for VCC and VBx supplies.

Pinout & Package

IR2135J is packaged in a 28-lead SOIC (wide body) surface-mount package with exposed thermal pad (not electrically connected). Pin assignments are validated per IRF PD60107 revX datasheet and match the 28-lead DIP and PLCC variants in functional layout.

Pin/Terminal	Circuit Role	Design Meaning
HIN1,2,3	High-side logic input	Inverted control signal for HO1,2,3; enables complementary PWM with LINx for half-bridge operation.
LIN1,2,3	Low-side logic input	Inverted control signal for LO1,2,3; synchronized with HINx to enforce deadtime via internal logic.
HO1,2,3	High-side gate drive output	Floating output referenced to VS1,2,3; drives gates of high-side N-MOS/IGBT with ±200 mA/±420 mA capability.
LO1,2,3	Low-side gate drive output	Ground-referenced output; directly drives low-side device gates with fast rise/fall times (90 ns/40 ns typ.).
VB1,2,3	High-side floating supply	Bootstrap capacitor connection point; supplies gate drive voltage for respective HOx channel (10–20 V range).
VS1,2,3	High-side floating return	Source/emitter node of high-side power device; defines local ground for VBx and HOx circuitry.
ITRIP	Over-current trip input	Analog input accepting voltage from external sense resistor; triggers shutdown when ≥570 mV (typ.) is detected.
CA+, CA−, CAO	Current amplifier interface	Dedicated op-amp inputs/outputs for closed-loop current sensing; supports gain-setting resistors and filtering.
FAULT	Open-drain fault indicator	Active-low signal asserted during UVLO or over-current; requires external pull-up for system-level fault reporting.
FLT-CLR	Fault clear input	Negative-logic input; deasserts FAULT after over-current event when held low for ≥850 ns (typ.).
SD	Global shutdown input	Asynchronous disable of all six outputs; overrides PWM inputs and holds HOx/LOx low until cleared.
VCC	Fixed logic supply	Primary power for logic core, low-side drivers, and internal amplifiers; regulated 10–20 V required.
VSS	Logic ground reference	Return path for VCC and all logic-level signals; must be tightly coupled to COM for noise immunity.
COM	Low-side power return	Common return for LOx outputs and current-sense amplifier; connects to system power ground plane.

Key Features

Feature	Design Value
Floating channel architecture	Enables bootstrap-based high-side drive up to +600 V VS offset without external level shifters or isolated supplies.
Matched propagation delay	≤50 ns max skew between any HO/LO pair ensures precise timing alignment critical for vector-controlled motor drives.
Integrated current-sense amplifier	Provides rail-to-rail output (0–5 V) with 70 dB CMRR, eliminating need for external op-amp in shunt-based phase current measurement.
Independent UVLO per supply	Dual undervoltage lockout (VCC and VBx) prevents partial drive activation and ensures safe startup/shutdown sequencing.
Programmable blanking time	400 ns internal ITRIP blanking window suppresses false trips during switching transients without external RC networks.

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
IR2133J	Same pinout and function but rated for 600 V VS offset only; lacks enhanced UVLO hysteresis (0.4 V vs. 1.0 V in IR2135J).	Lower-cost option for 230 VAC systems where tighter UVLO margin is not required.	Select IR2133J only if operating VCC/VBx supplies are highly stable and system-level fault recovery is handled externally.
IRS2336JD2	Monolithic 3-phase driver with integrated bootstrap diodes; 600 V rating; no integrated current-sense amplifier or ITRIP input.	Reduces external component count for bootstrap but requires separate current sensing and protection circuitry.	Choose IRS2336JD2 when board space is constrained and current monitoring is implemented digitally via ADC sampling.

Compared with IR2133J and IRS2336JD2, the IR2135J uniquely combines 600 V robustness, integrated analog current sensing, and programmable fault management-making it optimal for safety-critical, high-reliability motor control where analog loop integrity and fast over-current response are mandatory.

FAQ

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

The IR2135J is specified as dV/dt immune up to 50 V/ns under normal operating conditions. This immunity is achieved through proprietary level-shifting circuitry within the HVIC process, allowing stable operation even during fast-switching transients in 600 V bridge configurations without false turn-on of high-side drivers.

Can the CA+ and CA− inputs be used with bidirectional current sense resistors?

Yes-the CA+ and CA− inputs accept differential voltage across a bidirectional shunt resistor. The internal amplifier has rail-to-rail output and supports both unidirectional and bidirectional current sensing; polarity is preserved in CAO output, enabling full-wave current reconstruction for FOC algorithms.

Is external bootstrap diode required when using VB1,2,3 pins?

Yes-an external fast-recovery or Schottky diode is required between VCC and each VBx pin to charge the bootstrap capacitor during low-side conduction. The IR2135J does not integrate bootstrap diodes; omission causes insufficient high-side gate drive voltage and potential shoot-through.

How does the ITRIP blanking time interact with PWM frequency and minimum pulse width?

The internal 400 ns ITRIP blanking window is fixed and non-adjustable. It ensures that current-sense faults are ignored during the first 400 ns after any switching edge, preventing false trips during gate-drive ringing. At 20 kHz PWM, this represents <0.8% of the period-well below minimum controllable on-time in most motor control implementations.
