Product details

Overview

AUIRS2117STR from Infineon Technologies (formerly International Rectifier) is a single-channel high-side gate driver IC designed for driving N-channel MOSFETs and IGBTs in automotive BLDC motor control, piezo injector, and high-voltage switching applications. It operates with floating channel architecture up to +600 V offset, supports 10–20 V gate drive supply, delivers 290 mA source / 600 mA sink peak output current, and features in-phase logic-to-HO response with undervoltage lockout on both VCC and VBS rails.

For engineers reviewing the AUIRS2117STR datasheet, AUIRS2117STR pinout, AUIRS2117STR application, or AUIRS2117STR equivalent, this page provides verified technical context, validated pin functions, confirmed automotive-grade qualification (AEC-Q100), real-world timing specs (140 ns tON/tOFF), and direct alternative comparisons - all grounded in the official July 2014 datasheet and Infineon product documentation.

Technical Context

The AUIRS2117STR integrates a high-voltage level shifter and latch-immune CMOS logic to enable robust high-side operation across −5 V to +600 V VS offset range. Its HVIC monolithic construction ensures dV/dt immunity up to 50 V/ns and withstands negative transients without false triggering.

It uses Schmitt-triggered CMOS inputs with internal pull-down (distinguishing it from the AUIRS2118STR's pull-up), delivers in-phase HO output relative to IN, and implements independent UVLO detection on both VCC (7.2–9.6 V hysteresis) and VBS (7.2–9.6 V hysteresis) to prevent shoot-through during under-supply conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Topology	Single high-side driver - drives external N-channel power device in high-side configuration only
V_OFFSET max	600 V - enables direct connection to 400 V DC bus systems (e.g., automotive traction inverters)
I_O+/I_O−	290 mA / 600 mA - sufficient to charge/discharge 1 nF gate capacitance in <100 ns at 15 V V_BS
t_ON/t_OFF	140 ns / 140 ns - supports PWM switching up to ~3 MHz with minimal dead-time uncertainty
V_CC range	10 V – 20 V - compatible with standard 12 V/15 V automotive logic supplies
UVLO thresholds	V_CC: 7.2–9.6 V; V_BS: 7.2–9.6 V - dual-rail lockout prevents partial turn-on during bootstrap capacitor discharge
Qualification	AEC-Q100 Grade 1 (−40°C to +125°C T_A) - qualified for engine bay and powertrain applications

Pinout & Package

Package: 8-Lead SOIC (SOIC-8N), RoHS-compliant, MSL3 per J-STD-020.

Pin/Terminal	Circuit Role	Design Meaning
1 VCC	Logic and low-side supply input	Provides bias for internal logic and level shifter; referenced to COM
2 IN	CMOS Schmitt-trigger input	Pull-down enabled; rising edge on IN directly enables HO (in-phase)
3 COM	Logic ground reference	Common return for VCC, IN, and internal logic; isolated from VS/VB domain
4 NC	No connection	Internally unconnected; must remain floating or grounded per layout guidelines
5 NC	No connection	Internally unconnected; must remain floating or grounded per layout guidelines
6 VS	Floating supply return	Return path for high-side driver stage; referenced to VB; carries switching node voltage
7 HO	High-side gate drive output	Drives gate of external N-MOSFET/IGBT; swings from VS to VB (up to 600 V offset)
8 VB	Floating supply input	Connects to bootstrap capacitor top; supplies high-side driver stage; referenced to VS

Key Features

Feature	Design Value
Floating channel architecture	Enables high-side gate drive without isolated supplies; relies on bootstrap capacitor charged via external diode
dV/dt immune level shifting	Withstands 50 V/ns transient on VS node - prevents false turn-on in noisy motor drive environments
Dual-rail undervoltage lockout	Independent UVLO on VCC and VBS ensures gate remains off if either rail drops below 7.2 V
In-phase logic-to-output mapping	HO follows IN state directly - simplifies control logic vs. inverted drivers like AUIRS2118STR
AEC-Q100 qualified	Validated for automotive powertrain use including engine control, EV battery management, and e-axle inverters

Equivalent & Alternatives

The following parts are listed as comparable options for similar high-side gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRS2117PbF	Same die, non-automotive grade; lacks AEC-Q100 qualification and extended temperature rating (−40°C to +125°C)	Suitable for industrial/commercial motor drives but not automotive powertrain or safety-critical systems	Select when AEC-Q100 is not required and cost sensitivity outweighs qualification needs
IR2117S	Identical electrical specs and pinout; differs only in packaging marking and tape/reel orientation per ordering code	No functional difference; used interchangeably where automotive qualification is not mandated	Choose for legacy designs or non-automotive production where Infineon part numbering conventions apply

Compared with IRS2117PbF and IR2117S, the AUIRS2117STR provides guaranteed automotive qualification, tighter parametric screening over temperature, and traceable lot-level compliance - making it the sole choice for OEM powertrain programs requiring AEC-Q100 documentation and long-term supply continuity.

FAQ

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

The AUIRS2117STR is rated for up to 50 V/ns dV/dt on the VS pin under recommended operating conditions. This specification is validated per the July 2014 datasheet and ensures immunity to false triggering during fast-switching events in motor drive and inverter applications. Layout practices - including minimized VS loop area and proper decoupling - are essential to maintain this performance in system-level implementation.

Can AUIRS2117STR drive IGBTs directly?

Yes, the AUIRS2117STR can directly drive N-channel IGBTs requiring gate drive voltages between 10 V and 20 V and peak gate currents within its 290 mA source / 600 mA sink capability. Its 600 V offset rating and robust dV/dt immunity make it suitable for IGBTs in 400 V-class inverters, provided external gate resistor values are selected to limit peak current and control switching speed per the IGBT's datasheet.

Is bootstrap capacitor charging supported internally?

No, the AUIRS2117STR does not include internal bootstrap diode or charge pump. An external fast-recovery diode must be placed between VCC and VB to charge the bootstrap capacitor during low-side conduction. The VB pin accepts the charged capacitor's positive terminal, and VS serves as its return - this external bootstrap network is mandatory for sustained high-side operation.

What is the purpose of pins 4 and 5 (NC)?

Pins 4 and 5 are no-connect terminals - they are not bonded internally and must remain unconnected in the PCB layout. Neither pin should be tied to ground, VCC, or any other net. Leaving them floating is acceptable, but grounding them is also permitted per Infineon's layout guidance to reduce potential EMI coupling; no electrical function is affected either way.
