Product details

Overview

IR2131J from Infineon Technologies is a high-voltage, high-speed 3-phase gate driver IC with independent floating high-side and grounded low-side output channels. It delivers ±160 mA / ±360 mA peak output current, supports up to 600 V offset voltage, operates with 10–20 V gate drive supply, and features matched 1.3 µs / 0.6 µs typical turn-on/turn-off propagation delays-designed for driving N-channel MOSFETs or IGBTs in motor inverter stages.

For engineers reviewing the IR2131J datasheet, IR2131J pinout, IR2131J application, or IR2131J equivalent, key selection criteria include high-side floating channel robustness (dV/dt immune), integrated over-current shutdown via external sense resistor, undervoltage lockout per channel, 2.5 V logic compatibility, and fault reporting via open-drain FAULT output.

Technical Context

The IR2131J integrates six independent drivers-three high-side channels with bootstrap-referenced floating supplies (VB1–VB3, VS1–VS3) and three low-side channels referenced to VSS/COM-enabling full-bridge or 3-phase inverter topologies. Each high-side channel tolerates VS transients up to 600 V and dV/dt up to 50 V/ns without false triggering.

It implements dual protection: an ITRIP input accepts voltage from an external current-sense resistor to trigger simultaneous shutdown of all six outputs within 700 ns, while separate UVLO thresholds (8.3 V nominal) monitor both VBS and VCC supplies. The FAULT pin asserts low on any UVLO or over-current event and clears only after FLT-CLR pulse.

Key Specifications

Parameter	Value and Actual Design Meaning
VOFFSET max	600 V - enables direct high-side drive of 600 V-class power switches without level-shifting circuitry
IO+ / IO−	160 mA / 360 mA - sufficient peak current to charge/discharge gate capacitance of medium-power MOSFETs/IGBTs at high frequency
VOUT range	10–20 V - configurable gate drive voltage supporting both logic-level and standard-threshold power devices
ton / toff (typ.)	1.3 µs / 0.6 µs - tightly matched propagation delays across all six channels simplify dead-time control in 3-phase PWM
Logic threshold	2.2 V VIH / 0.8 V VIL - compatible with 2.5 V, 3.3 V, and 5 V CMOS/LSTTL logic without level translation
ITRIP threshold	485 mV (typ.) - precise analog over-current detection point enabling fast, repeatable trip response using small-value sense resistors
FAULT output	Open-drain, active-low - allows wired-OR fault bus implementation across multiple drivers in multi-phase systems

Pinout & Package

IR2131J is packaged in a 28-lead PDIP (Plastic Dual In-line Package) with wide-body outline (MS-011AB), suitable for through-hole prototyping and industrial PCB assembly. Thermal resistance R_thJA is 83 °C/W under still-air conditions.

Pin/Terminal	Circuit Role	Design Meaning

VCC	Logic & low-side supply	10–20 V input powering internal logic, low-side drivers, and level-shift circuitry
VSS	Logic ground reference	Reference for all logic inputs (HIN/LIN/SD/FLT-CLR/ITRIP); tied to COM in most layouts
COM	Power ground return	Common return for low-side outputs (LO1–LO3); must be low-inductance path to system ground
ITRIP	Over-current sense input	Analog input accepting voltage from external shunt; triggers global shutdown when >485 mV (typ.)
SD	Shutdown control input	Active-high digital input forcing all outputs low; threshold 1.8 V (typ.), hysteresis 0.3 V
FLT-CLR	Fault clear input	Pulse-driven reset for FAULT latch; requires >100 ns low pulse to release FAULT output
FAULT	Fault status output	Open-drain, active-low signal indicating UVLO or over-current event on any channel

Key Features

Feature	Design Value

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IR2130J	Omits FAULT output and FLT-CLR input; no open-drain fault reporting capability	Not suitable for systems requiring centralized fault bus or automatic fault clearing	Select IR2131J when coordinated fault signaling across multiple drivers is required
IRS2136D	Includes built-in bootstrap diode per high-side channel; higher VCC UVLO (11.4 V)	Reduces external component count but less tolerant of low-VCC brown-out conditions	Prefer IRS2136D for cost-sensitive designs where board space is constrained and VCC stability is assured

Compared with IR2130J and IRS2136D, the IR2131J uniquely combines full fault visibility (open-drain FAULT), programmable fault clearing (FLT-CLR), and tight propagation matching-making it optimal for safety-critical 3-phase inverters requiring deterministic fault handling and timing consistency.

FAQ

What is the maximum allowable dV/dt on the VS pins of the IR2131J?

The IR2131J is rated for up to 50 V/ns dV/dt on its VS1–VS3 pins under recommended operating conditions. This specification ensures immunity to fast transient coupling in high-power switching environments, preventing false turn-on of high-side drivers during commutation events. Testing per Figure 2 in the datasheet confirms stable operation without spurious output transitions at this rate.

Can the IR2131J drive SiC MOSFETs directly?

The IR2131J can drive SiC MOSFETs provided gate voltage requirements fall within its 10–20 V output range and gate charge is compatible with its ±160 mA/±360 mA peak output capability. However, due to SiC's faster switching and stricter Miller immunity needs, external negative gate turn-off or active Miller clamp circuits may be required-IR2131J does not integrate these functions.

How is the ITRIP threshold calibrated, and what is its temperature drift?

The ITRIP threshold is internally trimmed to 485 mV (typ.) at 25 °C, with min/max values of 250 mV and 600 mV across temperature and process variation. Datasheet Figure 5 shows ±10% drift over −40 °C to +125 °C ambient, making it suitable for industrial-grade current sensing without external compensation.

Is the IR2131J pin-compatible with the IR2131S or IR2131PbF variants?

Yes-the IR2131J (28-lead PDIP), IR2131S (28-lead SOIC), and IR2131PbF (lead-free versions) share identical pinouts and electrical specifications. Mechanical differences exist only in package type and RoHS compliance; no layout or schematic changes are needed when substituting between these variants.
