Product details

Overview

AUIRS2332J from Infineon Technologies (formerly International Rectifier) is an automotive-grade 3-phase high- and low-side gate driver IC designed for N-channel MOSFET/IGBT half-bridge control in motor inverters. It features six independent drivers, integrated operational amplifier for current sensing, 600 V floating channel capability, 540 ns matched propagation delay, and over-current shutdown with FAULT flag. Used in automotive 3-phase brushless DC motor drives for pumps and fans.

For engineers reviewing the AUIRS2332J datasheet, AUIRS2332J pinout, AUIRS2332J application, or AUIRS2332J equivalent, key selection criteria include bootstrap-compatible high-side operation up to +600 V, 3.3 V logic compatibility, integrated current-sense amplifier with 490 mV ITRIP threshold, and automotive AEC-Q100 qualification with MSL3 moisture sensitivity rating.

Technical Context

The AUIRS2332J integrates three independent high-side and three low-side drivers in a single monolithic HVIC, each with matched t_ON/t_OFF (540 ns typ.) and built-in cross-conduction prevention logic. Its floating channels tolerate dV/dt transients up to 50 V/ns and operate with VS offset from –8 V to +600 V relative to VSO.

The embedded operational amplifier provides ground-referenced current feedback via external sense resistor, with 5 V/µs slew rate (+), 40 mV VOL,AMP, and 20 mV input offset. Over-current detection triggers simultaneous shutdown of all six outputs within 625 ns (t_ITRIP), signaled by open-drain FAULT output.

Key Specifications

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
IRS2336M	Same pinout and function but non-automotive grade; lacks AEC-Q100 qualification and tighter temp range (–40 °C to +105 °C)	Not suitable for safety-critical automotive modules; acceptable for industrial BLDC drives	Select only if AEC-Q100 is not required and ambient temperature stays below 105 °C
BD63001FV	Integrated 3-phase pre-driver with built-in charge pump (no external bootstrap diodes); lower max VOFFSET (450 V)	Requires no external bootstrap capacitors; limited to ≤400 V DC bus systems	Prefer when board space is constrained and 600 V capability is unnecessary

Compared with IRS2336M and BD63001FV, the AUIRS2332J uniquely combines AEC-Q100 qualification, 600 V floating capability, and integrated current-sense amplifier-making it the only choice for automotive 3-phase motor control where functional safety, high-voltage robustness, and analog feedback integration are jointly required.

FAQ

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

The AUIRS2332J is rated for 50 V/ns dV/dt immunity on its high-side floating channels (VS1–VS3), verified per AEC-Q100 stress testing. This ensures reliable operation during fast-switching transitions in 400 V DC bus inverters without false triggering or latch-up, even under worst-case parasitic inductance conditions.

Does the integrated operational amplifier require external compensation?

No external compensation is required. The amplifier is internally compensated for unity-gain stability with a 5 V/µs slew rate and 1 MHz gain-bandwidth product. It operates reliably with standard 1% tolerance shunt resistors and typical PCB trace capacitance (<10 pF) without oscillation or phase margin issues.

How does the FAULT output behave during undervoltage lockout?

During VCC or VBS undervoltage (below 7.9 V for VBS, 8.6 V for VCC), the FAULT pin pulls low and remains asserted until both supplies recover above their respective hysteresis thresholds (VBSUVH = 0.4 V, VCCUVH = 0.3 V). All six outputs are disabled simultaneously and remain off until FAULT clears.

Can the ITRIP input be used with a differential current sense amplifier?

No-the ITRIP input is a single-ended, ground-referenced comparator input with fixed 490 mV threshold. It accepts only the voltage drop across one side of a shunt resistor (typically low-side). Differential amplifiers must feed into the CA−/CA+ amplifier inputs instead; ITRIP is not compatible with differential signals.
