Product details

Overview

AUIRS2301STR from Infineon Technologies (formerly International Rectifier) is an automotive-grade high- and low-side gate driver IC designed for driving N-channel MOSFETs or IGBTs in three-phase inverter half-bridge configurations. It supports 600V floating operation, delivers 200mA/350mA peak output current, features matched 220ns/200ns propagation delays, and operates with 5–20V gate supply voltage - used in automotive motor drives and servo inverters.

For engineers reviewing the AUIRS2301STR datasheet, AUIRS2301STR pinout, AUIRS2301STR application, or AUIRS2301STR equivalent, key selection criteria include bootstrap-compatible floating channel capability, dV/dt immunity up to 50 V/ns, AEC-Q100 qualification, undervoltage lockout on both channels, and 3.3V/5V/15V logic compatibility.

Technical Context

The AUIRS2301STR integrates a high-voltage level-shifting circuit and latch-immune CMOS logic to enable independent control of high-side (HO) and low-side (LO) outputs referenced to floating (VS) and ground-referenced (COM) domains. Its HVIC monolithic construction ensures robust operation under fast transient conditions.

It implements dual-channel undervoltage lockout (UVLO) with 4.1V turn-on and 3.8V turn-off thresholds for both VCC and VBS supplies, and maintains phase-aligned input-to-output timing with ≤50ns delay mismatch between channels across -40°C to +125°C ambient.

Key Specifications

Parameter	Value and Actual Design Meaning
VOFFSET Max	600V - Enables direct high-side drive in 400V DC-link automotive inverters without external level shifters.
I_O+/I_O− (typ)	200mA / 350mA - Sufficient gate charge delivery for <100nC MOSFETs at >20kHz switching frequencies.
t_ON/t_OFF (typ)	220ns / 200ns - Supports precise PWM timing control in servo and micro-inverter applications.
Delay Matching	≤50ns - Ensures symmetrical dead-time implementation and minimizes shoot-through risk in half-bridge topologies.
V_IN Logic Compatibility	3.3V, 5V, 15V - Interfaces directly with MCU GPIOs, FPGA outputs, and isolated gate drivers without level translation.
dV/dt Immunity	50 V/ns - Withstands rapid voltage transients during IGBT/MOSFET switching in noisy motor drive environments.
UVLO Thresholds	VCC/VBS: 4.1V (rising), 3.8V (falling) - Prevents partial turn-on during power-up/down and brownout conditions.

Pinout & Package

8-Lead SOIC (Small Outline Integrated Circuit) package with standard gull-wing leads, RoHS-compliant, MSL3 moisture sensitivity rating, and lead temperature tolerance up to 300°C for reflow soldering.

VCC	Low-side and logic supply input	Provides regulated 5–20V power for internal logic and LO driver stage.
COM	Ground reference for low-side and logic circuits	Common return path for VCC, LIN, LO, and internal bias networks.
LO	Low-side gate driver output	Drives N-channel MOSFET/IGBT source-connected to COM with 350mA sink capability.
HIN	High-side logic input	Accepts 3.3V/5V/15V logic signal; controls HO output via internal level shifter.
LIN	Low-side logic input	Directly controls LO output with CMOS/LSTTL-compatible thresholds.
HO	High-side gate driver output	Floats with VS node; delivers 200mA source current to drive high-side switch gate.
VB	High-side floating supply input	Connects to bootstrap capacitor; powers high-side driver stage referenced to VS.
VS	Floating source reference for high-side channel	Node tied to high-side switch source; defines offset domain for HO and VB operation.

Key Features

Feature	Design Value
Floating channel architecture	Enables bootstrap-based high-side drive up to +600V offset without external isolation components.
Matched propagation delay	≤50ns difference between HO and LO channel delays ensures precise synchronous switching in half-bridges.
Integrated UVLO per channel	Independent undervoltage protection on VCC and VBS prevents unreliable gate drive during supply sag or startup.
Lower di/dt gate driver design	Reduces EMI susceptibility and improves noise margin in high-power motor control PCB layouts.
AEC-Q100 qualified	Validated for automotive use including temperature cycling, HTOL, and ESD (HBM ±2kV, CDM ±1kV).

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
IRS21844STRPBF	Non-automotive grade; lacks AEC-Q100 qualification and tighter UVLO hysteresis (0.5V vs. 0.3V).	Approved for industrial inverters only; not suitable for EPS or brake actuator designs requiring ASIL compliance.	Select when cost sensitivity outweighs automotive qualification requirements and ambient temperature stays ≤105°C.
BD63730FJ-E2	Higher V_OFFSET (650V), but lower I_O− (250mA vs. 350mA); no dV/dt rating published.	Used in HVAC compressors; lacks documented ESD robustness data for automotive harness environments.	Prefer for higher DC-link voltage margin where gate charge demand is moderate and system-level EMC filtering is enhanced.

Compared with IRS21844STRPBF and BD63730FJ-E2, the AUIRS2301STR uniquely combines AEC-Q100 qualification, 50 V/ns dV/dt immunity, and matched 220/200 ns delays - making it the only choice for safety-critical automotive half-bridge drives requiring guaranteed timing symmetry and transient resilience.

FAQ

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

The AUIRS2301STR is rated for 50 V/ns dV/dt immunity at the VS pin under all operating conditions. This specification is verified per AEC-Q100 stress testing and ensures reliable operation during fast-switching events in 400–600V DC-link inverters without false triggering or latch-up.

Can the AUIRS2301STR drive SiC MOSFETs?

Yes - its 200mA/350mA peak output current, 220ns/200ns propagation delays, and 5–20V gate supply range support common 1200V SiC MOSFETs with Q_g ≤ 80nC. However, external negative gate voltage clamping is recommended for robust turn-off in high-dV/dt SiC applications.

Is bootstrap operation mandatory for the high-side channel?

No - while optimized for bootstrap configuration, the AUIRS2301STR's floating channel also supports isolated DC-DC supply for V_B, enabling operation in high-duty-cycle or 100% high-side conduction scenarios where bootstrap capacitor recharge is impractical.

Does the device include internal shoot-through protection?

No - the AUIRS2301STR provides independent HIN/LIN inputs without integrated logic-based dead-time insertion. Shoot-through prevention must be implemented externally via MCU-controlled PWM dead-time generation or dedicated gate driver controllers.
