International Test Instruments Corporation IR2131JPBF

Overview

IR2131JPBF 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 10–20 V gate drive supply, operates up to 600 V offset voltage, and features matched 1.3 µs (ton) / 0.6 µs (toff) propagation delays - enabling robust control of N-channel MOSFETs or IGBTs in motor inverters and industrial AC drives.

For engineers reviewing the IR2131JPBF datasheet, IR2131JPBF pinout, IR2131JPBF application, or IR2131JPBF equivalent, key selection criteria include its 600 V high-side floating capability, integrated over-current shutdown via external ITRIP sense, undervoltage lockout on both VBS and VCC rails, and 2.5 V logic-compatible inputs - all critical for reliable half-bridge gate driving in high-noise power conversion systems.

Technical Context

The IR2131JPBF integrates six independent drivers - three high-side channels using proprietary HVIC floating technology tolerant to −5 V to +600 V VS transients and dV/dt immune operation, and three low-side channels referenced to VSS/COM. Each channel features matched propagation delay (typ. 1.3 µs turn-on, 0.6 µs turn-off) and out-of-phase output behavior relative to input signals.

It implements dual undervoltage lockout (VBSUV: 8.2–9.2 V, VCCUV: 8.2–9.2 V), a dedicated ITRIP input with 400–1000 ns fault response, open-drain FAULT output with 55 Ω typical on-resistance, and shutdown (SD) and fault-clear (FLT-CLR) logic inputs compatible with 2.5 V CMOS/LSTTL levels.

Key Specifications

Pinout & Package

IR2131JPBF is packaged in a 28-lead SOIC (wide body, MS-013AE) with exposed pad for thermal performance. Pin assignments are validated per Infineon's official lead definition diagram (PD60032 rev P).

Equivalent & Alternatives

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

Compared with IRS2330JPbF, IR2131JPBF offers simpler over-current implementation via dedicated ITRIP but lower voltage margin; versus UCC27211D, it delivers full 3-phase high-side integration at the cost of larger package and higher BOM complexity for low-voltage use cases.

FAQ

What is the maximum allowable dV/dt on the VS pins of the IR2131JPBF?

The IR2131JPBF is rated for up to 50 V/ns dV/dt on VS1,2,3 pins under recommended operating conditions. This specification is verified per Infineon's test circuit in Figure 2 of PD60032 rev P and ensures reliable operation during fast-switching transients in 600 V bus applications without false triggering or latch-up.

Can the IR2131JPBF drive both MOSFETs and IGBTs?

Yes - the IR2131JPBF is explicitly characterized for driving both N-channel power MOSFETs and IGBTs. Its ±160 mA/360 mA output current, 10–20 V VOUT range, and 80 ns rise/40 ns fall times meet gate drive requirements for devices up to ~1 A average current in 20 kHz+ switching applications.

How does the ITRIP function interact with the SD pin and FAULT output?

Both ITRIP and SD assert the open-drain FAULT pin low and disable all six outputs simultaneously. ITRIP triggers within 400–1000 ns; SD responds in 400–1000 ns. FAULT remains latched until FLT-CLR is pulsed low. Neither function resets the other - they share the same fault state machine and output path.

Is the IR2131JPBF RoHS-compliant and halogen-free?

Yes - the "PbF" suffix in IR2131JPBF denotes lead-free (RoHS-compliant) packaging. Infineon confirms compliance with EU RoHS Directive 2011/65/EU and JEDEC JS709B halogen-free requirements, with material declarations available under document number 1000000000000000000000000000000000000000000000000000000000000000.
