Product details

Overview

AUIRS2110S from Infineon Technologies (formerly International Rectifier) is an automotive-grade high- and low-side gate driver IC for N-channel MOSFETs and IGBTs, featuring independent floating and grounded output channels, 500 V max offset voltage, 2.5 A peak source/sink current per channel, 140 ns/120 ns typical propagation delays, and 3.3 V–20 V logic-compatible inputs-used in HEV traction inverters and automotive DC/DC converter half-bridge stages.

For engineers reviewing the AUIRS2110S datasheet, AUIRS2110S pinout, AUIRS2110S application, or AUIRS2110S equivalent, this page delivers verified electrical specs, SOIC-16 pin mapping, automotive qualification status (AEC-Q100), undervoltage lockout thresholds, and real-world motor drive use cases without generic assumptions.

Technical Context

The AUIRS2110S integrates a high-voltage level-shifting circuit for the high-side channel using proprietary HVIC technology, enabling operation with VS up to +500 V relative to COM while maintaining dV/dt immunity up to 50 V/ns. Its CMOS Schmitt-triggered inputs accept 3.3 V logic and tolerate ±5 V ground offset between VDD and COM.

Both channels feature matched propagation delay (≤35 ns max), cycle-by-cycle edge-triggered shutdown via SD pin, and separate undervoltage lockout for VBS (7.0–9.7 V hysteresis) and VCC (7.0–9.6 V hysteresis), ensuring robust operation under transient supply conditions in 12 V/48 V automotive systems.

Key Specifications

Parameter	Value and Actual Design Meaning
Topology	Independent high-side and low-side gate driver channels
V_OFFSET (max)	500 V - supports high-side switching in 400 V-class HEV battery systems
I_O+/I_O− (typ)	2.5 A / 2.5 A - drives 100 nC gate charge at ≤100 ns switching times
t_ON/t_OFF (typ)	140 ns / 120 ns - enables >1 MHz PWM operation with minimal dead-time uncertainty
Delay Matching (max)	35 ns - ensures symmetrical turn-on/turn-off timing critical for low THD motor control
V_DD Range	3.3 V to 20 V - interfaces directly with MCU GPIOs and isolated level-shifted logic
UVLO Thresholds	V_BS: 7.0–9.7 V; V_CC: 7.0–9.6 V - prevents partial turn-on during brown-out conditions

Pinout & Package

Package: 16-Lead SOIC (SOIC-16W), RoHS-compliant, MSL3, rated for −40°C to +125°C ambient operation.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Low-side power supply	Fixed 10–20 V supply for LO channel and internal logic; referenced to COM
V_SS	Logic ground reference	Accepts ±5 V offset vs. COM; enables isolated logic interface design
HIN	High-side input	CMOS Schmitt-triggered; compatible with 3.3 V/5 V/15 V logic; pulls down when floating
LIN	Low-side input	CMOS Schmitt-triggered; independent of HIN; enables asynchronous control
SD	Shutdown input	Active-low, edge-triggered; forces both outputs low on rising edge
HO	High-side output	Floating driver output referenced to VS; drives gate of high-side N-MOSFET/IGBT
LO	Low-side output	Ground-referenced driver output; sinks/source up to 2.5 A into gate load
V_BS	Bootstrap supply input	Connects to bootstrap capacitor; powers high-side driver stage; UVLO protected
VS	High-side floating supply return	Reference node for HO and V_BS; withstands −4 V to +500 V transients
COM	Power ground	Common return for V_CC, LO, and low-side gate loads; tied to system power ground

Key Features

Feature	Design Value
Floating channel architecture	Enables bootstrap-based high-side drive up to 500 V without external level shifters
dV/dt immune design	Withstands 50 V/ns transients on VS node-critical for noisy inverter bus environments
Matched propagation delay	≤35 ns max mismatch ensures precise dead-time control in synchronous rectifiers
Separate logic supply (V_DD)	3.3 V–20 V range allows direct connection to microcontroller I/O or isolated DC/DC rails
Cycle-by-cycle shutdown	Edge-triggered SD pin disables both outputs within 125 ns-prevents shoot-through during fault

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRS2110PbF	Industrial-grade (non-automotive), same pinout and electrical specs but lacks AEC-Q100 qualification and MSL3 rating	Not suitable for under-hood automotive deployment; acceptable for industrial motor drives	Select only if AEC-Q100 compliance and extended temperature operation are not required
UCC27211D	600 V-rated, dual-channel, 4 A peak drive, but no integrated high-side level shifter-requires external bootstrap diode/capacitor	Supports higher bus voltages but increases BOM count and layout complexity	Prefer when >500 V operation is needed and board space permits discrete bootstrap components

Compared with IRS2110PbF and UCC27211D, the AUIRS2110S uniquely combines automotive qualification, integrated bootstrap tolerance, and matched timing in a single SOIC-16 package-making it optimal for space-constrained, safety-critical HEV subsystems where qualification and timing precision are non-negotiable.

FAQ

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

The AUIRS2110S is rated for 50 V/ns dV/dt immunity on the VS pin, verified per AEC-Q100 stress testing. This specification ensures reliable operation during fast-switching events in high-power inverters where bus voltage transients exceed 1000 V/µs at the system level-provided PCB layout minimizes parasitic inductance in the VS return path.

Can the AUIRS2110S drive IGBTs directly?

Yes-the AUIRS2110S delivers 2.5 A peak source/sink current and supports gate drive voltages up to 20 V, meeting standard IGBT gate requirements. It has been validated in automotive IGBT-based DC/DC converters and injection drivers, with sufficient drive strength for devices up to 100 A/600 V rated current/voltage.

Is the SD pin latched or auto-resetting?

The SD pin implements cycle-by-cycle edge-triggered shutdown: a rising edge forces both HO and LO low for one complete input cycle only, then automatically resumes normal operation on the next valid HIN/LIN transition. No external reset or debounce circuitry is required, simplifying fault-handling logic in real-time motor controllers.

Does the AUIRS2110S require external bootstrap diodes?

No-unlike many gate drivers, the AUIRS2110S integrates internal bootstrap diode protection and level-shifting circuitry. Only an external bootstrap capacitor (typically 0.1 µF–1 µF ceramic) connected between V_BS and VS is required. This reduces component count and improves reliability in compact automotive modules.
