Product details
Overview
AUIRS2301S from Infineon Technologies (formerly International Rectifier) is an automotive-grade high- and low-side gate driver IC for N-channel MOSFETs and IGBTs, featuring independent floating high-side and grounded low-side output channels, 600V offset voltage rating, 220ns/200ns typical propagation delays, and 3.3V–20V logic-compatible inputs-used in three-phase inverter stages of electric power steering and HVAC compressor drives.
For engineers reviewing the AUIRS2301S datasheet, AUIRS2301S pinout, AUIRS2301S application, or AUIRS2301S equivalent, key selection criteria include bootstrap-enabled high-side operation up to +600V, matched channel timing (≤50ns delay mismatch), undervoltage lockout on both VCC and VBS supplies, and AEC-Q100 qualification for under-hood automotive environments.
Technical Context
The AUIRS2301S integrates a high-voltage level-shifting circuit with latch-immune CMOS logic to enable robust high-side drive referenced to a floating VS node. Its HVIC process supports dV/dt immunity up to 50 V/ns and withstands negative transients during switching transitions.
Both HIN and LIN inputs accept standard CMOS/LSTTL logic levels down to 3.3V, with separate undervoltage lockout thresholds (4.1V rising, 3.8V falling) for VCC and VBS supplies. Output drivers deliver 200mA source / 350mA sink peak current into capacitive loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET Max | 600V - Enables high-side drive in bridge configurations with bus voltages up to 600V DC without external level shifters |
| tON / tOFF Typ | 220ns / 200ns - Ensures tight timing control in high-frequency PWM inverters (e.g., >20 kHz motor control) |
| Delay Matching | ≤50ns - Minimizes shoot-through risk in complementary half-bridge switching by synchronizing HO/LO edge alignment |
| IO+ / IO− Typ | 200mA / 350mA - Sufficient gate charge delivery for 1–2 µC gate capacitance at ≤100 ns rise/fall times |
| VIN Logic Range | 3.3V–20V compatible - Supports direct interface with microcontrollers, DSPs, and isolated gate drivers without level translation |
| UVLO Thresholds | VCC/VBS: 4.1V (rising), 3.8V (falling) - Prevents erratic output behavior during brown-out or bootstrap capacitor discharge |
| AEC-Q100 Grade | Qualified - Validated for automotive applications including temperature cycling (−40°C to +125°C ambient), ESD (HBM ±2kV), and latch-up (Class II) |
Pinout & Package
8-Lead SOIC (Small Outline Integrated Circuit) package with exposed thermal pad; RoHS-compliant, MSL3, lead temperature rated to 300°C for 10 seconds.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side and logic supply input | Provides regulated 5–20V bias for internal logic and LO driver; decoupling required near pin |
| COM | Ground reference for low-side outputs and logic | Common return path for LO, LIN, and internal circuitry; must be low-inductance connection to PCB ground plane |
| LO | Low-side gate drive output | Drives N-channel MOSFET/IGBT source-connected to COM; 350mA sink capability minimizes turn-off delay |
| HIN | High-side logic input | CMOS/LSTTL-compatible signal controlling HO; referenced to COM, not VS or VB |
| LIN | Low-side logic input | Directly controls LO; enables independent or complementary PWM control when paired with HIN |
| HO | High-side gate drive output | Floating output referenced to VS; drives gate of high-side N-channel device in bootstrap configuration |
| VS | Floating source reference for high-side channel | Return node for HO; swings from −5V to +600V relative to COM; critical for bootstrap capacitor placement |
| VB | Bootstrap supply input for high-side driver | Accepts charged bootstrap capacitor (typically 0.1–1 µF); regulates internal high-side supply for HO stage |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel architecture | Enables self-contained high-side drive without external level shifters or isolated supplies in half-bridge topologies |
| dV/dt immune design | Withstands 50 V/ns transient voltage slew rates on VS node-prevents false triggering during fast switching transitions |
| Matched propagation delay | ≤50ns difference between HO and LO turn-on/turn-off edges-reduces dead-time uncertainty and improves PWM fidelity |
| Lower di/dt gate drive | Controlled output edge rates reduce EMI generation and improve noise immunity in noisy automotive harness environments |
| 3.3V–20V input logic compatibility | Eliminates need for external level translators when interfacing with modern MCU GPIOs or isolated digital isolators |
Applications
| Electric Power Steering (EPS) | HVAC Compressor Drive |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar high- and low-side gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS21844S | Higher peak output current (600mA/600mA), no integrated UVLO hysteresis on VBS, same 8-SOIC package | Preferred for higher gate charge loads (>2.5 µC) and non-automotive industrial inverters | Select when higher drive strength is needed and AEC-Q100 is not required |
| UCC27211A | 600V-rated but single high-side + single low-side (non-integrated bootstrap), 4A peak drive, thermally enhanced SOIC-8 | Suited for designs requiring independent bootstrap management or higher thermal margin | Choose when board-level thermal design permits discrete bootstrap control and higher current is critical |
Compared with IRS21844S and UCC27211A, the AUIRS2301S uniquely combines AEC-Q100 qualification, matched timing, and integrated bootstrap supply monitoring-making it optimal for safety-critical automotive inverters where timing predictability and qualification compliance outweigh raw drive strength.

FAQ
What is the maximum allowable dV/dt on the VS pin?
The AUIRS2301S is rated for dV/dt immunity up to 50 V/ns on the VS pin, verified per AEC-Q100 stress testing. This specification ensures reliable operation during fast-switching events in 400V–600V bus applications without false triggering of the high-side driver stage.
Can the AUIRS2301S drive SiC MOSFETs?
The AUIRS2301S can drive low-to-mid gate charge SiC MOSFETs (Qg < 1.5 nC) in 600V-class topologies, provided external gate resistors limit di/dt and layout minimizes parasitic inductance. It is not optimized for the higher gate drive voltage requirements (≥15V) typical of high-power SiC devices.
Is a bootstrap diode required, and what type is recommended?
Yes-a fast recovery or Schottky bootstrap diode is mandatory between VCC and VB. A 1N4148W or PMEG4010AEB is recommended: reverse voltage ≥40V, forward current ≥100mA, trr < 4ns, and low forward voltage to minimize bootstrap capacitor recharge losses.
Does the AUIRS2301S support 50% duty cycle high-side operation?
No-due to bootstrap architecture limitations, continuous 100% high-side duty cycle is not supported. For sustained high-side conduction, a charge pump or isolated DC-DC supply is required. The device supports >95% duty cycle only with periodic low-side conduction to refresh the bootstrap capacitor.
