Product details

Overview

AUIRS2336S from Infineon Technologies (formerly International Rectifier) is an automotive-grade 3-phase high- and low-side gate driver IC designed to control six N-channel IGBTs or MOSFETs in motor inverter stages. It features matched 530 ns propagation delays, integrated 275 ns deadtime, 600 V offset capability, 200 mA/350 mA peak output drive, and operates from –40°C to 125°C for HVAC compressor and brushless automotive traction inverters.

For engineers reviewing the AUIRS2336S datasheet, AUIRS2336S pinout, AUIRS2336S application, or AUIRS2336S equivalent, key selection criteria include bootstrap-compatible high-side floating operation up to 600 V, 3.3 V logic compatibility, over-current trip via external resistor, fault reporting with RC-programmable clear timing, and AEC-Q100 qualification for under-hood deployment.

Technical Context

The AUIRS2336S integrates three independent high-side and three low-side drivers in a single monolithic HVIC structure using latch-immune CMOS technology. Each channel delivers 200 mA sink / 350 mA source current with <530 ns tON/tOFF and built-in shoot-through prevention via hardware-enforced minimum deadtime.

It supports bootstrap power supplies for high-side operation with VB–VS ≤ 600 V and tolerates –50 V transient VS offsets. Logic inputs (HIN/LIN/EN/ITRIP) are 3.3 V compatible, and fault signaling uses an open-drain FAULT output with RCIN-programmable auto-clear delay.

Key Specifications

Parameter	Value and Actual Design Meaning
Topology	3-phase bridge driver with 3 high-side + 3 low-side outputs
V_OFFSET max	600 V - enables direct connection to 400 V DC bus with margin for transients
I_O+/I_O− (typ)	200 mA / 350 mA - sufficient to charge/discharge 1000 pF gate capacitance in <100 ns
t_ON/t_OFF (typ)	530 ns / 530 ns - matched delays simplify PWM timing alignment across all six channels
Deadtime (typ)	275 ns - hardware-enforced minimum prevents cross-conduction in IGBT/MOSFET half-bridges
Logic supply	3.3 V compatible - interfaces directly with automotive microcontrollers without level-shifting
Operating temp	–40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood motor control

EN	Global enable/disable	Active-high input disabling all six outputs simultaneously; 2.5 V threshold ensures noise immunity
FAULT	Open-drain fault indicator	Asserted low during UVLO, over-temperature, or over-current; requires external pull-up

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
IRS2336PbF	Industrial-grade variant (non-AEC-Q100); identical electrical specs but rated for –40°C to +105°C only	Not qualified for automotive under-hood use; suitable for industrial HVAC or white goods	Select when AEC-Q100 is not required and cost sensitivity outweighs extended temperature range
IR2136S	Legacy 3-phase driver with 600 V rating but no integrated ITRIP comparator or RCIN fault clear; requires external sensing circuitry	Lacks built-in over-current trip and programmable fault recovery; higher system-level design effort	Choose only if legacy design reuse or pin compatibility with older IR2136-based layouts is mandatory

Compared with IRS2336PbF and IR2136S, the AUIRS2336S uniquely combines AEC-Q100 qualification, integrated current-sense trip, and RC-programmable fault recovery-reducing external component count and qualifying for ASIL-B–aligned motor control systems without additional safety mechanisms.

FAQ

What is the maximum allowable dV/dt on the VS pin?

The AUIRS2336S is rated for up to 50 V/ns dVS/dt on the VS pin, ensuring reliable operation during fast-switching transients in high-frequency inverter applications. This specification is verified per AEC-Q100 stress testing and applies across the full –40°C to +125°C operating range with proper PCB layout and gate loop inductance control.

How is over-current protection implemented?

Over-current protection uses the ITRIP pin to monitor voltage across an external shunt resistor. When the sensed voltage exceeds 0.46 V (typical), the IC immediately disables all six outputs and asserts the FAULT pin low. Recovery occurs automatically after the RCIN-programmed delay once the fault condition clears and UVLO thresholds are re-established.

Can the AUIRS2336S drive SiC MOSFETs?

Yes-the AUIRS2336S can drive SiC MOSFETs provided gate drive voltage remains within 10–20 V and gate loop inductance is minimized. Its 350 mA sink current and 530 ns propagation delay meet typical SiC gate requirements, though layout optimization and external gate resistors may be needed to manage dv/dt and ringing in high-speed switching.

What is the purpose of the separate VSS and COM pins?

VSS serves as the reference for all logic inputs (HIN/LIN/EN/ITRIP/FAULT/RCIN), while COM is the power ground for low-side drivers and VCC. This separation prevents noise coupling from high-current switching paths into sensitive logic circuits, improving noise immunity and enabling clean signal integrity in noisy automotive ECU environments.
