Product details
Overview
AUIRS2004S 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 and low-side configurations. It operates with floating channel up to +200 V offset, supports 10–20 V gate drive supply, features internally set 520 ns deadtime, undervoltage lockout, and 3.3/5/15 V logic compatibility - used in motor/pump drives and DC-DC converters.
For engineers reviewing the AUIRS2004S datasheet, AUIRS2004S pinout, AUIRS2004S application, or AUIRS2004S equivalent, key selection criteria include VS tolerance (200 V), matched propagation delay (≤150 ns), cross-conduction prevention logic, shutdown input behavior, and AEC-Q100 qualification for automotive power stages.
Technical Context
The AUIRS2004S integrates a high-side floating channel using HVIC technology with latch-immune CMOS, enabling robust operation under fast dV/dt transients (up to 50 V/ns). Its dual-channel architecture provides in-phase high-side output and complementary low-side output with internal deadtime generation and matched turn-on/turn-off delays.
Logic inputs (IN, SD) accept 3.3 V to 15 V signals with defined thresholds (VIH ≥2.5 V, VIL ≤0.8 V), while undervoltage lockout triggers at VCCUV+ = 8.9 V (typ.) and releases at VCCUV− = 8.2 V (typ.). Output drive capability is rated at 130 mA (HO) and 270 mA (LO) pulsed short-circuit current.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VS Offset Voltage | 200 V max - enables high-side switching in buck, half-bridge, and 3-phase inverter topologies with 200 V bus rails |
| VCC Supply Range | 10–20 V - supports standard gate drive voltage levels for Si and SiC power devices |
| IO+ / IO− Drive Current | 130 mA / 270 mA - sufficient to charge/discharge typical 1–3 nF gate capacitances within nanosecond timing constraints |
| tON / tOFF | 680 ns / 150 ns - ensures precise PWM edge placement and minimal shoot-through risk in high-frequency switching |
| Deadtime (DT) | 520 ns typ. - fixed internal deadtime prevents simultaneous conduction of high- and low-side switches |
| Logic Compatibility | 3.3 V, 5 V, 15 V - interoperable with microcontrollers, DSPs, and FPGA I/O without level-shifting |
| UVLO Thresholds | VCCUV+ = 8.9 V, VCCUV− = 8.2 V - hysteresis prevents oscillation during marginal supply conditions |
Pinout & Package
Package: 8-Lead SOIC (Small Outline Integrated Circuit), RoHS-compliant, MSL3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Logic input for both HO and LO outputs | In-phase signal controls high-side output directly and low-side output complementarily via internal logic |
| SD | Shutdown input (active-low) | Pulls both HO and LO low when asserted; enables system-level fault recovery and safe power-down |
| VB | Floating high-side supply rail | Connects to bootstrap capacitor; supplies gate drive for high-side N-channel device referenced to VS |
| HO | High-side gate drive output | Drives gate of high-side MOSFET/IGBT; referenced to VS, capable of +200 V offset operation |
| VS | Floating high-side return / source node | Reference point for HO output and VB supply; tracks switching node voltage in half-bridge configuration |
| VCC | Fixed low-side and logic supply | Provides bias for internal logic, low-side driver, and level-shift circuitry; 10–20 V range |
| LO | Low-side gate drive output | Drives gate of low-side N-channel device; referenced to COM, synchronous with IN but inverted |
| COM | Low-side ground reference | Common return for VCC, LO, IN, and SD; forms logic ground and low-side source connection |
Key Features
| Feature | Design Value |
|---|---|
| Floating channel with dV/dt immunity | Rated for 50 V/ns transient immunity - suppresses false triggering during fast-switching transitions in noisy power stages |
| Internally set deadtime | 520 ns typ. - eliminates need for external timing components and reduces PCB layout complexity |
| Cross-conduction prevention logic | Hardware-enforced non-overlap between HO and LO - guarantees safe commutation without software or external logic |
| Matched propagation delay | ≤150 ns mismatch between HO and LO paths - maintains precise PWM duty cycle fidelity across temperature and supply variation |
| AEC-Q100 qualified | Automotive Grade 0 (−40°C to +125°C TJ) - validated for engine bay, transmission, and EV traction auxiliary systems |

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 |
|---|---|---|---|
| IRS2004S | Industrial-grade version; same pinout and electrical specs but not AEC-Q100 qualified; MSL1 vs MSL3 | Lacks automotive qualification and extended temperature validation; unsuitable for under-hood deployment | Select only for non-automotive industrial DC-DC or motor control where cost sensitivity outweighs qualification requirements |
| UCC27211D | TI part with 4 A peak drive, no integrated deadtime, requires external deadtime circuit; 120 V VS rating | Higher drive strength but lower VS rating and no internal safety logic; needs additional components for shoot-through protection | Prefer when >270 mA drive is required and board space allows discrete deadtime implementation |
Compared with IRS2004S and UCC27211D, AUIRS2004S uniquely combines AEC-Q100 qualification, 200 V VS tolerance, and hardware-enforced deadtime - making it optimal for automotive half-bridge power stages where reliability, integration, and qualification are mandatory.

FAQ
What is the maximum allowable dV/dt at the VS pin?
The AUIRS2004S is specified to tolerate up to 50 V/ns dV/dt on the VS pin under recommended operating conditions. This rating is verified per AEC-Q100 stress testing and ensures reliable operation during fast-switching transients in half-bridge topologies without false triggering or latch-up.
Does the AUIRS2004S require external bootstrap diode and capacitor?
Yes - the AUIRS2004S requires an external bootstrap diode and capacitor connected between VB and VS to generate the floating high-side supply. The bootstrap capacitor must be sized to maintain >10 V on VB during high-side conduction, typically 0.1–1 µF ceramic with low ESR, and the diode must support reverse voltage >200 V and forward current >10 mA.
How does the shutdown (SD) pin behave during fault conditions?
When SD is pulled low (≤0.8 V), both HO and LO outputs are forced low immediately, independent of IN state. The internal logic holds outputs disabled until SD returns high (>2.5 V); no automatic recovery occurs. This behavior supports fail-safe system design in automotive applications requiring deterministic fault response.
Is the AUIRS2004S compatible with silicon carbide (SiC) MOSFETs?
Yes - the AUIRS2004S supports 10–20 V gate drive and delivers 130 mA/270 mA peak output current, aligning with typical SiC MOSFET gate charge requirements (Qg ≈ 10–30 nC). Its 200 V VS rating and fast propagation delays (680 ns/150 ns) enable reliable switching of 650 V SiC devices in hard-switched topologies.
