Product details
Overview
AUIRS20302S from Infineon Technologies (formerly International Rectifier) is an automotive-grade, monolithic three-phase high- and low-side gate driver IC for BLDC motor control up to 600W. It integrates pre-regulated VPR supply generation, cross-conduction prevention logic, matched 530 ns propagation delays per channel, 200 V floating offset capability, and current-sense comparator with 6 µs blanking time - deployed in 24V–200V battery-powered HVAC and pump drives.
For engineers reviewing the AUIRS20302S datasheet, AUIRS20302S pinout, AUIRS20302S application, or AUIRS20302S equivalent, key selection criteria include its 200 V high-side offset rating, 3.3 V logic compatibility, latched fault detection with FRST-controlled reset, bootstrap UVLO monitoring per phase, and pre-regulator MOSFET integration enabling stable 8–17 V gate drive under load dump conditions.
Technical Context
The AUIRS20302S implements a dedicated HVIC-based architecture with independent high-side floating channels (VB1–VB3/VS1–VS3), each featuring integrated level-shifting, dead-time insertion (700 ns typ.), and shoot-through protection. Its pre-regulator loop actively controls an external MOSFET via VCP to maintain VPR at 13–15 V across 6–17 V input range.
Current sensing uses differential CAN/CAP inputs with ±33 mV offset and 7 µA bias current, feeding a comparator that triggers a latched FAULT output within 1.2 µs. Logic inputs (HIN/LIN/EN/FRST) include 270 ns noise-filtering and operate down to 1.9 V threshold, supporting direct interfacing with 3.3 V microcontrollers.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Topology | Three-phase high- and low-side gate driver with independent bootstrap channels |
| VOFFSET (max) | 200 V - enables operation with VS up to COM + 200 V, covering automotive load dump transients |
| VOUT (HO/LO) | 8.0–17 V - regulated gate drive voltage range, enforced by internal pre-regulator loop |
| tON / tOFF (typ.) | 530 ns / 530 ns - matched propagation delay ensures synchronous switching and precise timing control |
| Io+ / Io− (typ.) | 0.20 A / 0.35 A - peak source/sink current sufficient to drive 1000 pF gate loads at <100 ns rise/fall |
| Deadtime (typ.) | 0.7 µs - hardware-enforced minimum off-time prevents shoot-through during commutation |
| tBLANK (typ.) | 6 µs - synchronized over-current blanking window avoids false triggering during switching transitions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar three-phase gate driver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| IRS2007STRPBF | Lacks integrated pre-regulator; requires external 12 V supply; no VPR output; lower 100 V offset rating | Suitable for 12 V industrial BLDC drives without load dump stress; not qualified to AEC-Q100 | Select when cost sensitivity outweighs automotive qualification and VPR system integration needs |
| UCC27211D | Single-channel, non-isolated driver; no bootstrap or floating channel support; 120 V max VBS | Requires external high-side level shifters and discrete dead-time control; limited to low-voltage (<40 V) motor drives | Choose only for custom multi-chip 3-phase designs where layout control and thermal separation are prioritized |
Compared with IRS2007STRPBF and UCC27211D, the AUIRS20302S uniquely integrates pre-regulation, 200 V offset, AEC-Q100 qualification, and per-phase UVLO - making it the only single-package solution for automotive 24 V–200 V BLDC drives requiring functional safety-aware fault management.

FAQ
What is the maximum allowable high-side floating voltage (VOFFSET) for AUIRS20302S?
The AUIRS20302S supports a maximum high-side offset voltage of 200 V, defined as the potential difference between VBx and VSx. This rating is validated per AEC-Q100 and allows reliable operation during automotive load dump events up to 36 V battery transients while maintaining 200 V headroom for VS node swing.
How does the VPR pre-regulator function, and what external components are required?
The VPR pre-regulator uses an external N-channel MOSFET controlled by the internal VCP charge pump to regulate the VPR pin to 13–15 V across 6–17 V input. Only one external MOSFET and its gate resistor are required; no external feedback network or LDO is needed. VPR can supply up to 100 mA to external logic or sensors.
What is the correct sequence to clear a latched FAULT condition?
To clear a latched FAULT, first pull EN low (0 V), then apply a >20 µs pulse to FRST, and finally re-enable EN high (≥1.9 V). The FAULT pin remains low until this full sequence completes; attempting FRST pulsing with EN high has no effect and may cause undefined behavior per datasheet truth table.
Does AUIRS20302S support independent current sensing per motor phase?
No - the AUIRS20302S provides a single differential current sense input pair (CAN/CAP) shared across all three phases. It is intended for single-shunt or DC-link sensing, not per-phase shunt measurement. For phase-resolved current feedback, external amplifiers or multiplexed sensing must be added upstream of CAN/CAP.
