Product details
Overview
IR2131JTR from Infineon Technologies is a high-voltage, high-speed 3-phase gate driver IC with independent high-side and low-side outputs. It integrates six drivers (3 high-side, 3 low-side), supports up to 600 V offset voltage, delivers ±160 mA / +360 mA peak output current, operates with 10–20 V gate supply, and features matched 1.3 µs / 0.6 µs typical propagation delays. It is used in 3-phase motor inverters for industrial AC drives.
For engineers reviewing the IR2131JTR datasheet, IR2131JTR pinout, IR2131JTR application, or IR2131JTR equivalent, key selection criteria include floating channel dV/dt immunity, integrated over-current shutdown via ITRIP, undervoltage lockout per channel, 2.5 V logic compatibility, and SOIC-28 package thermal performance.
Technical Context
The IR2131JTR employs proprietary HVIC (High-Voltage IC) technology enabling monolithic integration of level-shifted high-side drivers tolerant to −5 V to +600 V VS transients and immune to >50 V/ns dV/dt. Each high-side channel uses bootstrap operation with dedicated VBx/VSx terminals and internal UVLO thresholds at 8.2–9.2 V.
All six logic inputs (HIN1–3, LIN1–3, SD, FLT-CLR, ITRIP) are CMOS/LSTTL-compatible down to 2.5 V, with input filtering (310 ns) and independent shutdown paths. The FAULT pin provides open-drain indication of UVLO or over-current events, while matched propagation delays simplify PWM dead-time design in high-frequency 3-phase topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET max | 600 V - enables direct driving of N-channel MOSFETs/IGBTs in high-side legs of 3-phase bridge inverters up to 400 VAC line-to-line systems |
| IO+ / IO− | 160 mA / 360 mA - sufficient peak current to charge/discharge 1 nF gate capacitance in <100 ns, supporting 100 kHz+ switching in motor control |
| VCC range | 10–20 V - compatible with standard 12 V or 15 V gate drive supplies; includes UVLO with hysteresis (8.3 V ±0.5 V) |
| ton / toff typ | 1.3 µs / 0.6 µs - tightly matched across all six channels, minimizing phase skew in synchronized 3-phase PWM |
| Input logic threshold | VIH ≥ 2.2 V, VIL ≤ 0.8 V - ensures reliable interfacing with 3.3 V microcontrollers without level-shifting |
| ITRIP threshold | 400–600 mV - allows precise current-sense resistor selection (e.g., 10 mΩ yields 40–60 A trip point) for fast over-current protection |
| Thermal resistance RthJA | 78 °C/W (SOIC-28) - limits junction temperature rise to ≤45 °C at 1.6 W dissipation under still-air conditions |
Pinout & Package
IR2131JTR is packaged in a 28-lead wide-body SOIC (MS-013AE) with exposed pad thermal enhancement. Pin assignments follow JEDEC MS-013AE outline and support board-level layout per IRF Design Tip DT97-3 for noise immunity and bootstrap stability.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| HIN1,2,3 | Logic input for HO1,2,3 | Inverted control signal path; enables complementary PWM generation without external inverters |
| LIN1,2,3 | Logic input for LO1,2,3 | Direct-drive low-side outputs; synchronized with HIN but non-inverted |
| VB1,2,3 | High-side floating supply | Bootstrap capacitor connection point; must be ≥10 V above VSx to enable high-side output |
| VS1,2,3 | High-side floating return | Source/negative terminal of high-side power device; referenced to COM for level-shifting |
| HO1,2,3 | High-side gate drive output | Capable of sourcing 160 mA into gate capacitance; rated for 600 V offset relative to COM |
| LO1,2,3 | Low-side gate drive output | Sinks 360 mA; referenced to COM; supports fast turn-off of low-side switches |
| ITRIP | Over-current sense input | Analog input monitoring external shunt; triggers shutdown within 700 ns of fault detection |
| FAULT | Open-drain fault indicator | Pulled low on any UVLO or ITRIP event; requires external pull-up for system-level fault signaling |
| SD | Shutdown control input | Active-high logic input; forces all six outputs low and asserts FAULT when asserted |
| FLT-CLR | FAULT clear input | Active-low asynchronous reset; clears FAULT latch after fault condition is removed |
| VCC | Logic & low-side supply | Primary 10–20 V supply for internal logic, low-side drivers, and level-shift circuitry |
| VSS | Logic ground reference | Common reference for all logic inputs and low-side outputs; isolated from COM in PCB layout |
| COM | Power ground return | Return path for all output currents; must be low-inductance connection to minimize ground bounce |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables bootstrap-based high-side drive up to 600 V offset without external level shifters or isolated supplies |
| Matched propagation delay | 1.3 µs (ton) / 0.6 µs (toff) across all six channels ensures <50 ns phase skew in 3-phase PWM timing |
| Integrated over-current protection | ITRIP input with 400–600 mV threshold and 700 ns response enables cycle-by-cycle current limiting |
| Independent UVLO per supply | Dual UVLO (VBS and VCC) prevents partial operation; hysteresis avoids chatter near threshold |
| 2.5 V logic compatibility | Supports direct interface with 3.3 V MCUs and DSPs without external translators or resistive dividers |

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 |
|---|---|---|---|
| IR2130JTR | No ITRIP input; over-current protection requires external comparator and latch; lacks FAULT pin | Suitable only where current sensing is implemented externally or not required | Select when cost sensitivity outweighs integrated protection needs and board space permits discrete fault logic |
| IRS2330JPbF | Higher 650 V offset rating; 250 mA/650 mA output drive; no SD or FLT-CLR pins; different pinout | Better suited for higher bus voltages (e.g., 600 VDC systems); less flexible control interface | Choose for 650 V-class inverters needing higher drive strength, accepting reduced control granularity |
Compared with IR2130JTR and IRS2330JPbF, IR2131JTR uniquely combines integrated ITRIP-based over-current shutdown, active fault clearing (FLT-CLR), and full six-channel independence in SOIC-28 - making it optimal for compact, safety-conscious 3-phase motor drives below 600 V bus.

FAQ
What is the maximum allowable dV/dt at the VS pins?
The IR2131JTR is rated for up to 50 V/ns dV/dt at the VS1–3 pins under recommended operating conditions. This specification ensures reliable level-shifting during fast-switching transients in 3-phase bridges. Exceeding this rate may cause false triggering or temporary loss of high-side output. Layout best practices-such as minimizing loop area between VS and COM, using local ceramic decoupling, and routing VS traces away from noisy nodes-are essential to maintain immunity.
Can IR2131JTR drive SiC MOSFETs?
Yes, IR2131JTR can drive SiC MOSFETs provided gate drive voltage (10–20 V) and current (±160/360 mA) requirements are met, and switching speed is adjusted for gate resistance. However, its 1.3 µs turn-on delay and lack of negative gate drive limit hard-switching performance above 50 kHz. For high-frequency SiC applications, consider drivers with faster propagation (<100 ns), active Miller clamp, and programmable dead time.
How does the ITRIP input function during normal operation?
The ITRIP pin monitors voltage across an external current-sense resistor. When voltage exceeds the 400–600 mV threshold, the internal comparator triggers a 700 ns propagation delay before disabling all six outputs and asserting FAULT. During normal operation, ITRIP remains high-impedance (bias current <150 nA) and draws negligible power. No external pull-up or pull-down is required unless used for diagnostic voltage monitoring.
Is the SOIC-28 package of IR2131JTR lead-free compliant?
Yes, the IR2131JTR is manufactured in a lead-free (PbF) SOIC-28 package compliant with RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3. The device undergoes standard reflow profiles (peak 260 °C, 10 s), and the package marking includes "(PbF)" per Infineon's datasheet PD60032 rev P.
