Product details

Overview

AUIRS2117S from Infineon Technologies (formerly International Rectifier) is a single-channel high-side gate driver IC designed for bootstrap-based N-channel MOSFET/IGBT control in automotive and industrial power stages. It operates with floating channel 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 - used in BLDC motor inverters and direct fuel injection systems.

For engineers reviewing the AUIRS2117S datasheet, AUIRS2117S pinout, AUIRS2117S application, or AUIRS2117S equivalent, key selection criteria include its 600 V VS tolerance, dV/dt immunity, dual UVLO (VBS/VCC), CMOS Schmitt-trigger input with pull-down, and SOIC-8 automotive qualification per AEC-Q100.

Technical Context

The AUIRS2117S integrates a high-voltage level shifter and latch-immune CMOS logic to enable robust high-side switching in half-bridge topologies. Its floating channel references VS (not ground), allowing operation with VB up to 625 V and VS offset up to 600 V while maintaining logic integrity across -5 V to +600 V transient ranges.

It implements independent undervoltage lockout on both VBS and VCC rails (thresholds 7.2–9.6 V), features 140 ns typical propagation delay at VS = 600 V, and uses internal pulse filtering to suppress false triggering from noise or fast dV/dt transients up to 50 V/ns.

Key Specifications

Parameter	Value and Actual Design Meaning
Topology	Single high-side gate driver - drives external N-channel MOSFET/IGBT in high-side configuration only
V_OFFSET (VS)	600 V max - enables use in 400 V DC bus systems with margin for transients
I_O+/I_O−	290 mA / 600 mA - sufficient to charge/discharge 1000 pF gate capacitance in <150 ns
t_ON/t_OFF	140 ns / 140 ns typical - ensures matched switching timing critical for BLDC commutation
V_CC Range	10 V – 20 V - compatible with standard 12 V/15 V logic supplies and tolerant of rail variation
UVLO Thresholds	V_BS: 7.2–9.6 V, V_CC: 7.2–9.6 V - prevents partial turn-on during bootstrap capacitor discharge
ESD Rating	HBM Class H1B (±1000 V), CDM Class C4 (±1000 V) - meets automotive ESD robustness requirements

Pinout & Package

Package: 8-Lead SOIC (SOIC-8N), RoHS-compliant, MSL3, automotive-qualified per AEC-Q100.

Pin/Terminal	Circuit Role	Design Meaning
1 VCC	Logic and low-side supply input	Provides power to internal logic and level-shifter; referenced to COM
2 IN	CMOS Schmitt-trigger input	In-phase logic control signal (AUIRS2117); pull-down ensures default-low state
3 COM	Logic ground reference	Common return for VCC, IN, and internal logic; isolated from VS/HO domain
4 NC	No connection	Internally unconnected; must remain unpopulated or floating
5 NC	No connection	Internally unconnected; must remain unpopulated or floating
6 VS	Floating supply return	Reference node for high-side output HO; tracks switching node voltage up to 600 V
7 HO	High-side gate drive output	Drives gate of external N-MOSFET/IGBT; swings from VS to VB (up to 600 V above COM)
8 VB	Floating supply input	Connects to bootstrap capacitor top; supplies gate drive energy for HO stage

Key Features

Feature	Design Value
Floating channel architecture	Enables high-side gate driving without optocouplers or isolated supplies in bootstrap configurations
dV/dt immune level shifting	Withstands 50 V/ns transients on VS node - prevents false turn-on during hard-switching events
Dual independent UVLO	Separate monitoring of VBS and VCC ensures gate drive remains disabled if either supply drops below safe threshold
Automotive qualification	AEC-Q100 Grade 0 (–40°C to +125°C ambient), MSL3, and full ESD/latch-up compliance
CMOS Schmitt-trigger input	Hysteresis reduces sensitivity to noise; pull-down guarantees known state during power-up or open input

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	Industrial-grade (non-automotive), identical electrical specs, same SOIC-8 pinout	Lacks AEC-Q100 qualification, lower ESD ratings (HBM ±500 V), not rated for automotive temperature range	Select when cost-sensitive industrial designs do not require automotive reliability or extended temperature operation
UCC27712DR	TI part with 600 V capability, 4 A peak output, but requires external level shifter; no integrated UVLO on floating supply	Higher drive strength but increased BOM count and layout complexity; no native bootstrap support	Choose when >600 mA sink current is required and system-level UVLO can be implemented externally

Compared with IRS2117PbF and UCC27712DR, the AUIRS2117S uniquely combines automotive qualification, integrated dual UVLO, and bootstrap-ready architecture in a single SOIC-8 package - reducing design risk in safety-critical motor and powertrain systems.

FAQ

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

The AUIRS2117S is specified to tolerate up to 50 V/ns on the VS pin under recommended operating conditions. This dV/dt immunity is achieved via proprietary level-shifter design and internal pulse filtering, preventing false triggering during fast switching transitions in high-power inverters and SMPS applications.

Can AUIRS2117S drive SiC MOSFETs?

Yes - the AUIRS2117S supports gate drive for 650 V-class SiC MOSFETs when used within its 600 V VS rating and 10–20 V VCC range. Its 290 mA source / 600 mA sink capability and 140 ns propagation delay meet typical SiC gate drive requirements, though external gate resistors may be needed to limit di/dt.

Is pin 4 (NC) electrically isolated inside the IC?

Yes - pins 4 and 5 are confirmed as no-connect terminals in the die layout and bonding structure. They are not bonded to any internal circuitry and must remain unconnected on the PCB; routing traces or vias to these pins may compromise creepage/clearance or induce parasitic coupling.

How does the dual UVLO function during bootstrap capacitor charging?

The AUIRS2117S monitors VBS and VCC independently. During startup, if VBS falls below 7.2 V (negative-going threshold), HO is forced low regardless of IN state - preventing partial turn-on of the high-side switch before the bootstrap capacitor reaches minimum operational voltage.
