Product details

Overview

IR2135 from Infineon (formerly International Rectifier) is a high-voltage, high-speed 3-phase bridge driver IC with three independent high-side and low-side gate drive channels. It supports up to 600V offset voltage, delivers ±200 mA / +420 mA peak output current, features 750/700 ns typical turn-on/turn-off propagation delay, 250 ns matched deadtime, and integrated current-sense amplifier for over-current protection - used in motor inverters for HVAC compressors and industrial AC drives.

For engineers reviewing the IR2135 datasheet, IR2135 pinout, IR2135 application, or IR2135 equivalent, key selection considerations include floating channel operation up to 600V, bootstrap-compatible high-side drive, undervoltage lockout per channel, analog current feedback via CA+/CA−, and fault-clear functionality via FLT-CLR.

Technical Context

The IR2135 integrates three isolated high-side drivers using proprietary HVIC technology, enabling robust monolithic construction for operation with VS offset up to 600V referenced to COM. Each high-side channel uses a floating supply (VB1–VB3) and return (VS1–VS3), with logic inputs compatible down to 2.5V CMOS/LSTTL levels.

It embeds a precision current-sense amplifier (CA+, CA−, CAO) with 5–10 V/µs slew rate and 50–70 dB CMRR/PSRR, plus dedicated ITRIP comparator with 470–670 mV threshold and 400 ns blanking time. Fault signaling is open-drain FAULT with active-low assertion and asynchronous clear via FLT-CLR.

Key Specifications

Parameter	Value and Actual Design Meaning
VOFFSET max	600 V - maximum allowable high-side floating supply offset vs. COM, defining safe operating range for N-channel MOSFET/IGBT high-side switching.
IO+ / IO−	200 mA / 420 mA - peak source/sink current per output, sufficient to drive gate capacitance of ≤1 nF power devices at ≥20 kHz PWM.
ton / toff (typ.)	750 ns / 700 ns - matched propagation delays across all six channels, enabling precise timing control in high-frequency 3-phase inverters.
Deadtime (typ.)	250 ns - built-in non-overlap interval between LS turn-off and HS turn-on, preventing shoot-through in half-bridge legs.
VOUT range	10–20 V - gate drive supply range for VBx and VCC, supporting standard 12 V or 15 V bootstrap designs with transient tolerance up to 25 V.
ITRIP threshold	470–670 mV - adjustable over-current detection level across external sense resistor, enabling scalable current limiting without external comparators.
Amplifier gain	Fixed unity-gain - CAO outputs differential voltage (CA+ − CA−) directly, simplifying closed-loop current feedback in servo and vector-control systems.

Pinout & Package

IR2135 is available in 28-lead SOIC (wide body), 28-lead PDIP, and 44-lead PLCC (12 leads omitted) packages. All variants share identical pin function mapping.

Pin/Terminal	Circuit Role	Design Meaning
HIN1, HIN2, HIN3	High-side logic input	Inverted-phase PWM inputs controlling HO1–HO3; 2.5 V–5 V compatible, with 310 ns internal filtering.
LIN1, LIN2, LIN3	Low-side logic input	Inverted-phase PWM inputs controlling LO1–LO3; synchronized with HIN for complementary drive.
HO1, HO2, HO3	High-side gate output	Floating high-current outputs referenced to VS1–VS3; capable of sourcing 200 mA into capacitive gate loads.
LO1, LO2, LO3	Low-side gate output	Ground-referenced outputs sourcing 420 mA; designed for fast turn-on of low-side switches in 3-phase bridges.
VB1, VB2, VB3	High-side floating supply	Bootstrap capacitor connection points for high-side gate drive; rated for 10–20 V DC with 25 V transient tolerance.
VS1, VS2, VS3	High-side floating return	Source nodes of high-side power devices; serve as local ground references for respective VB supplies and HO outputs.
ITRIP	Over-current trip input	Analog input tied to external shunt; triggers shutdown when voltage exceeds 470–670 mV, with 400 ns blanking window.
FAULT	Open-drain fault indicator	Active-low signal asserting on UVLO or over-current; requires external pull-up and is cleared only by FLT-CLR pulse.
FLT-CLR	Fault clear input	Negative-logic asynchronous reset; initiates recovery after fault condition is removed, with 600–1100 ns clear latency.
CA+, CA−, CAO	Current amplifier interface	Differential input pair and single-ended output for real-time motor phase current monitoring and closed-loop control.
VCC, VSS, COM	Fixed supply & grounds	VCC powers logic and low-side drivers (10–20 V); VSS = logic ground; COM = low-side power return common to all LO outputs.

Key Features

Feature	Design Value
Floating channel architecture	Enables direct bootstrap-based high-side drive up to +600 V offset without external level shifters or isolated supplies.
Matched propagation delay	≤±50 ns variation across all six outputs ensures consistent timing in space-vector PWM and field-oriented control algorithms.
Integrated current-sense amplifier	Eliminates need for external op-amp and comparator in over-current protection, reducing BOM count and PCB area in inverter designs.
Independent UVLO per supply	Dual undervoltage lockout (VCC and VBx) prevents erratic switching during brown-out, with hysteresis (1.0 V) ensuring clean restart.
Programmable shutdown	Global SD input disables all outputs immediately; combined with FAULT/FLT-CLR, enables fail-safe system-level protection sequencing.

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
IR2133	Same pinout and architecture but rated for 600 V offset only; lacks ITRIP hysteresis and has lower VBSUV thresholds (7.2–9.2 V).	Suitable for lower-voltage inverters (<400 V bus); not recommended where 600 V margin or tighter current-sense accuracy is required.	Select IR2133 only if cost sensitivity outweighs need for extended VBSUV hysteresis and higher ITRIP threshold stability.
IRS2330M	Monolithic 3-phase driver with integrated bootstrap diodes; 600 V rating, but no analog current amplifier - only digital ITRIP comparator.	Reduces external component count for bootstrap, but requires external op-amp for analog current feedback loops.	Choose IRS2330M when board space is constrained and analog current sensing is not required; IR2135 preferred for sensorless FOC or torque control.

Compared with IR2133 and IRS2330M, the IR2135 uniquely combines 600 V floating capability, matched timing, and integrated unity-gain current amplifier - making it optimal for applications demanding both protection fidelity and analog loop integration in compact inverter designs.

FAQ

What is the maximum bootstrap capacitor voltage rating supported by IR2135?

The IR2135 VBx pins tolerate up to 25 V transient voltage, with recommended steady-state operation between 10 V and 20 V. This allows use of standard 25 V X7R ceramic capacitors with 20 % derating, ensuring reliable charge replenishment during high-duty-cycle PWM operation without overstress.

Can IR2135 drive SiC MOSFETs directly?

Yes - its 200 mA source / 420 mA sink capability, 750 ns propagation delay, and 90 ns rise time meet gate drive requirements for 1200 V SiC MOSFETs up to ~30 A, provided external negative turn-off bias and Miller clamp are implemented per layout best practices in Infineon Design Tip DT97-3.

How does the ITRIP blanking time prevent false triggering during switching transients?

The IR2135 incorporates a fixed 400 ns blanking window after each PWM edge, during which the ITRIP comparator is disabled. This suppresses false over-current detection caused by parasitic current spikes during device commutation - critical for stable operation in hard-switched inverters.

Is the CA amplifier internally compensated for unity-gain stability?

Yes - the CA amplifier is internally compensated for stable unity-gain operation with capacitive loads ≤100 pF. No external compensation is required; however, PCB trace length to the current sense resistor must be minimized and guarded to preserve CMRR and avoid oscillation.
