Product details

Overview

AUIRS2336STR from Infineon Technologies (formerly International Rectifier) is an automotive-grade 3-phase bridge gate driver IC designed to control six N-channel IGBTs or MOSFETs in high-voltage motor drive inverters. It features 600 V offset capability, matched 530 ns propagation delays, integrated shoot-through and deadtime protection, and operates from –40°C to 125°C for HVAC compressor and brushless DC motor control.

For engineers reviewing the AUIRS2336STR datasheet, AUIRS2336STR pinout, AUIRS2336STR application, or AUIRS2336STR equivalent, this device delivers verified 200 mA high-side and 350 mA low-side peak output current, 275 ns programmable deadtime, 3.3 V logic compatibility, and fault reporting via open-drain FAULT output - all critical for robust inverter design under automotive thermal and EMI constraints.

Technical Context

The AUIRS2336STR integrates three independent high-side and three low-side gate drivers using HVIC technology with latch-immune CMOS, enabling direct bootstrap-based high-side operation up to 600 V VS offset. Its floating channel architecture supports negative transient tolerance down to –50 V on VS with 50 ns pulse width.

It implements hardware-level protections including over-current detection via external ITRIP resistor, over-temperature shutdown input, dual undervoltage lockout (VCC and VBS), and enable-controlled global output disable. Fault clearing is externally adjustable via RCIN with 3–10 µs timing range.

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 - supports high-side switching in 400 V DC bus inverters
I_O+/I_O− (typ)	200 mA / 350 mA - sufficient to drive 100 nC gate charge at ≥10 kHz switching
t_ON/t_OFF (typ)	530 ns / 530 ns - matched delays reduce phase skew in PWM control
Deadtime (typ)	275 ns - prevents shoot-through during cross-conduction transitions
Logic supply	3.3 V compatible - interfaces directly with MCU GPIO without level-shifting
Operating temp	–40°C to +125°C - qualified per AEC-Q100 Grade 1 for under-hood use

Pinout & Package

Supplied in a 28-lead SOIC wide-body package (body width 7.6 mm, pitch 1.27 mm), thermally enhanced for automotive power applications. Pin assignments are validated per IR datasheet Rev. A (Oct 2010), page 12.

EN	Global enable/disable	Active-high input disabling all six outputs simultaneously
FAULT	Open-drain fault indicator	Asserted low on UVLO, over-temp, or over-current; requires external pull-up
RCIN	Fault clear timing input	RC network sets auto-clear delay (3–10 µs); hysteresis = 3 V
VCC	Low-side supply	10–20 V supply for logic and low-side drivers; clamped at 25 V
COM	Low-side ground	Power ground reference for VCC and LO outputs
VB1–VB3	Bootstrap supply inputs	Each connects to individual bootstrap capacitor for high-side floating supply
VS1–VS3	High-side floating returns	Each tied to source of corresponding high-side switch; handles –50 V to +600 V transients
VSS	Logic ground	Separate ground for logic inputs; isolated from COM to suppress noise coupling

Key Features

IC Role / Device Role / Timing Role: High-current gate driver delivering 350 mA sink current to rapidly discharge low-side MOSFET gates during torque transients.

Use Value: Supports fast torque response (<5 ms step response) with matched propagation delays minimizing phase error across motor windings.

Brushless DC Traction Motor Control

Onboard Charger (OBC) PFC + Inverter Stage

Use Scenario: Inverter stage in 48 V mild-hybrid traction systems powering rear-axle BLDC motors.

IC Role / Device Role / Timing Role: 600 V-rated bridge driver managing high-side switching with bootstrap supplies and VS transient immunity.

Use Value: Sustains reliable operation during load dump events (ISO 7637-2 Pulse 5a) due to –50 V VS tolerance and internal clamps.

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
IRS2336SPBF	Same die, lead-free SOIC-28 but non-automotive grade (no AEC-Q100 qualification)	Lacks automotive temperature range guarantee and stress test validation	Select only for industrial or consumer designs where –40°C to +105°C suffices
BD63002MUV	600 V 3-phase driver with integrated current sensing; no RCIN fault clear adjustment	Includes analog current monitor output; fixed 1 µs fault clear time	Prefer when real-time current feedback is required and programmable fault recovery is not needed

Compared with IRS2336SPBF, AUIRS2336STR adds AEC-Q100 qualification and extended 125°C junction rating; versus BD63002MUV, it trades integrated sensing for field-adjustable fault recovery and higher peak output current (350 mA vs. 250 mA).

FAQ

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

The AUIRS2336STR is rated for up to 50 V/ns dV/dt on VS pins relative to VSS, verified per absolute maximum ratings table. This enables reliable operation during fast-switching transitions in 600 V bus applications without false triggering or latch-up, provided PCB layout minimizes parasitic inductance in the high-side return path.

Can the FAULT pin be used to trigger a hardware reset of the MCU?

Yes - the open-drain FAULT pin can directly interface with an MCU's interrupt-capable GPIO configured with external pull-up. When asserted low (e.g., during over-current or UVLO), it delivers a deterministic, sub-microsecond response enabling immediate PWM disable and safe shutdown sequencing without software polling delay.

Is bootstrap operation mandatory, or can V_B be supplied from an isolated DC/DC converter?

Bootstrap operation is optional. The VB pins accept any floating 10–20 V supply referenced to their respective VS nodes. An isolated DC/DC converter may replace bootstrap capacitors to eliminate duty-cycle limitations and improve reliability in 100% duty-cycle or high-frequency (>100 kHz) applications.

How is propagation delay matching maintained across temperature?

Propagation delays are matched within ±15 ns over –40°C to +125°C due to monolithic HVIC process integration and matched transistor sizing in the driver core. This is verified in the "Parameter Temperature Trends" section (pages 14–29 of datasheet) and ensures <0.5° phase error at 20 kHz PWM in motor control loops.
