Product details
Overview
AUIRS2302S from Infineon Technologies (formerly International Rectifier) is an automotive-grade high-voltage half-bridge gate driver IC designed to control N-channel MOSFETs or IGBTs in high-side/low-side configurations. It features 600V floating channel operation, 120mA/250mA peak output current, 720ns/250ns typical propagation delays, internal 540ns deadtime, and 3.3V–15V logic compatibility - deployed in electric power steering and braking pump systems.
For engineers reviewing the AUIRS2302S datasheet, AUIRS2302S pinout, AUIRS2302S application, or AUIRS2302S equivalent, key selection criteria include VS transient tolerance (50 V/ns), matched propagation delay (≤60 ns), undervoltage lockout thresholds (3.8–5.2 V), shutdown input functionality, and SOIC-8 automotive qualification per AEC-Q100.
Technical Context
The AUIRS2302S integrates a high-voltage level-shifting circuit with latch-immune CMOS logic to enable robust bootstrap-based high-side drive up to +600V. Its floating channel supports VS transients up to 50 V/ns, and internal cross-conduction prevention logic enforces minimum 300ns deadtime between LO turn-off and HO turn-on.
It delivers in-phase high-side output relative to IN, supports ±5V logic/power ground offset, and uses separate VCC (5–20V) and VB (VS + 5V to VS + 20V) supply rails. Undervoltage lockout operates independently on both VCC and VBS with 0.3V hysteresis.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VOFFSET (max) | 600V - enables direct high-side drive of N-MOSFETs in 400–600V bus applications like EPS and brake pumps |
| IO+ / IO− (min) | 120mA / 250mA - sufficient gate charge delivery for ≤30nC MOSFETs at 100kHz switching |
| tON / tOFF (typ) | 720ns / 250ns - ensures precise timing control in motor phase-leg commutation |
| Delay Matching (max) | 60ns - maintains symmetrical switching edges critical for low EMI and reduced shoot-through risk |
| Internal Deadtime | 540ns - hard-coded safety interval preventing simultaneous conduction in half-bridge topology |
| VIN Logic Range | 3.3V, 5V, 15V compatible - interfaces directly with MCU GPIOs or isolated digital controllers without level shifters |
| dV/dt Immunity | 50 V/ns - sustains reliable operation during fast-switching transients in noisy automotive environments |
Pinout & Package
Package: 8-Lead SOIC (Small Outline Integrated Circuit), RoHS-compliant, MSL3, rated for −40°C to +150°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VCC | Low-side and logic supply rail | Fixed 5–20V input powering internal logic, level shifter, and LO driver stage |
| COM | Logic and low-side power ground reference | Common return for IN, SD, LO, and VCC; tolerant to ±5V offset vs. VS |
| IN | Input control signal for both channels | CMOS/LSTTL-compatible logic input; high = HO on / LO on (inverting low-side path) |
| SD | Shutdown control input | Active-high input forcing both HO and LO to high-impedance state when asserted |
| HO | High-side floating output | Drives gate of high-side N-MOSFET; referenced to VS, capable of +600V offset |
| VS | Floating supply return for high-side channel | Source node of high-side MOSFET; serves as local ground for HO driver and level shifter |
| LO | Low-side output | Non-isolated gate driver output referenced to COM; drives low-side N-MOSFET gate |
| VB | Floating high-side supply rail | Bootstrap-supplied voltage (VS + 5V to VS + 20V) powering HO driver stage |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel with dV/dt immunity | Withstands 50 V/ns negative VS transients without false triggering - essential for inverter leg stability |
| Matched propagation delay | ≤60 ns difference between HS/LS turn-on and turn-off delays - enables balanced PWM edge alignment |
| Integrated deadtime generation | Fixed 540 ns interlock prevents shoot-through during switching transitions without external timing components |
| Independent UVLO on VCC and VBS | Lockout activates at 3.8V with 0.3V hysteresis on both supplies - avoids partial drive during brownout |
| 3.3V–15V logic compatibility | Accepts standard microcontroller I/O levels without external translators - reduces BOM count and layout complexity |

Equivalent & Alternatives
The following parts are listed as comparable options for similar half-bridge gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS21844SPbF | Higher IO+ (290mA), no integrated deadtime, requires external RC timing | Suited for higher-power inverters needing >250mA gate drive but less timing-critical designs | Select when gate charge demand exceeds 30nC or when programmable deadtime is required |
| BD63730FJ-E2 | Lower VOFFSET (450V), AEC-Q100 qualified, built-in bootstrap diode | Better fit for 24V–48V systems with space-constrained layouts requiring integrated bootstrap path | Prefer for compact 48V mild-hybrid subsystems where 600V margin is unnecessary |
Compared with IRS21844SPbF and BD63730FJ-E2, the AUIRS2302S offers fixed safety timing, superior dV/dt immunity, and tighter delay matching - making it optimal for automotive safety-critical motor control where deterministic timing and transient resilience are mandatory.

FAQ
What is the maximum allowable dV/dt on the VS pin?
The AUIRS2302S is rated for 50 V/ns dV/dt on the VS pin under all operating conditions. This specification is validated per AEC-Q100 stress testing and ensures reliable operation during fast-switching transients in motor inverter legs without false turn-on or latch-up. Exceeding this rate may compromise timing accuracy or cause unintended high-side activation.
Does the AUIRS2302S require an external bootstrap diode?
Yes, the AUIRS2302S requires an external bootstrap diode and capacitor to generate the floating VB supply for the high-side driver. The IC does not integrate a bootstrap diode; typical implementation uses a fast recovery diode (e.g., 1N4148WS or equivalent) and ≥0.1µF ceramic capacitor between VB and VS. Layout must minimize loop inductance to sustain 600V operation.
How does the shutdown (SD) pin behave during fault conditions?
The SD pin is active-high and forces both HO and LO outputs into high-impedance state when driven above 2.5V. It has hysteresis (0.8V threshold on falling edge), ensuring noise-immune deactivation. During shutdown, internal bias circuits remain powered, allowing immediate resumption of normal operation upon SD deassertion - no reset or reinitialization is needed.
Is the AUIRS2302S pin-compatible with earlier IR21xx series drivers?
No, the AUIRS2302S is not pin-compatible with IR210x or IR218x drivers. While functionally similar, its pinout differs: SD replaces DIS, VB replaces VBS, and VS placement is optimized for reduced parasitic coupling. Migration requires PCB redesign. Electrical behavior (e.g., deadtime, UVLO thresholds) also differs - full validation is required before substitution.
