Product details

Overview

AUIRS2113S from Infineon Technologies (formerly International Rectifier) is an automotive-grade high- and low-side gate driver IC designed to independently control N-channel MOSFETs or IGBTs in half-bridge configurations. It supports up to 600 V offset voltage, delivers ±2.5 A peak output current, features matched 140 ns / 120 ns propagation delays, and operates with 3.3 V–20 V logic supply and 10 V–20 V gate drive supply - used in HEV traction inverters and automotive DC/DC converters.

For engineers reviewing the AUIRS2113S datasheet, AUIRS2113S pinout, AUIRS2113S application, or AUIRS2113S equivalent, key selection criteria include its AEC-Q100 qualification, dV/dt immune floating channel, cycle-by-cycle shutdown logic, CMOS/Schmitt-triggered 3.3 V-compatible inputs, and ±5 V logic/power ground offset tolerance.

Technical Context

The AUIRS2113S integrates two independent HVIC channels: a high-side driver with bootstrap-referenced floating supply (VB/VS) capable of +600 V offset, and a low-side driver referenced to COM. Both channels feature undervoltage lockout (VBSUV: 7.0–9.7 V, VCCUV: 7.0–9.6 V) and edge-triggered shutdown (SD pin).

Its propagation delays are tightly matched (≤35 ns max difference), rise/fall times are 25 ns/15 ns typical, and it maintains logic compatibility across –4 V to +600 V VS range while tolerating ≥50 V/ns dV/dt transients - enabling robust operation in noisy high-voltage motor drive environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Max V_OFFSET	600 V - enables direct high-side driving of 600 V-class power switches in HEV inverters
I_O+/I_O− (typ)	±2.5 A - sufficient to rapidly charge/discharge gate capacitance of >100 nC MOSFETs at 100 kHz
t_ON/t_OFF (typ)	140 ns / 120 ns - supports switching frequencies up to 1 MHz with minimal dead-time uncertainty
Delay Matching (max)	35 ns - ensures symmetrical timing for complementary PWM, reducing shoot-through risk
V_DD Range	3.3 V–20 V - allows direct interface with 3.3 V microcontrollers without level-shifting
dV/dt Immunity	50 V/ns - prevents false triggering during fast high-side switching transitions
AEC-Q100 Grade	Qualified - certified for automotive powertrain applications per stress test requirements

Pinout & Package

Package: 16-Lead SOIC (Wide-body, 0.300" width), RoHS-compliant, MSL3, rated for –40°C to +125°C ambient operation.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Low-side gate supply	Provides 10–20 V bias for LO output stage; must be decoupled near pin
V_SS	Logic ground reference	Accepts ±5 V offset vs. COM - isolates logic domain from power noise
HIN	High-side input	CMOS/Schmitt-triggered; active-high, 3.3 V–20 V compatible
LIN	Low-side input	CMOS/Schmitt-triggered; active-high, independent of HIN timing
SD	Shutdown control	Active-low, edge-triggered; forces both outputs low on rising edge
HO	High-side gate output	Floating output referenced to VS; drives external N-MOSFET gate
LO	Low-side gate output	Ground-referenced output; drives N-MOSFET gate tied to COM
V_B	Floating supply top	Connects to bootstrap capacitor positive; supplies HO driver stage
V_S	Floating supply return	References HO output; tracks high-side switch source node
COM	Power ground	Reference for LO, V_CC, and all current-sense paths; connects to system ground

Key Features

Feature	Design Value
Floating channel with bootstrap operation	Enables high-side drive without isolated supplies - reduces BOM cost and board area in half-bridge designs
Separate logic supply (V_DD)	Decouples MCU I/O voltage (3.3 V) from gate drive rail (15 V), eliminating level shifters
Cycle-by-cycle edge-triggered shutdown	Prevents latch-up during fault events by forcing immediate, synchronized HO/LO disable
Matched propagation delay (≤35 ns)	Minimizes timing skew between channels - critical for precise dead-time control in SiC/GaN systems
CMOS Schmitt-triggered inputs with pull-down	Ensures deterministic startup state and noise immunity in automotive EMI environments

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
IRS21844SPBF	500 V max V_OFFSET, no separate V_DD supply, non-AEC-Q100	Targeted at industrial AC/DC SMPS, not automotive powertrain	Select only for cost-sensitive non-automotive designs where 600 V rating and AEC-Q100 are unnecessary
UCC27211D	600 V rating, single-input dual-output, no built-in UVLO on V_BS, non-AEC-Q100	Designed for high-efficiency server PSUs, lacks cycle-by-cycle shutdown	Use when simplified control interface suffices and automotive qualification is not required

Compared with IRS21844SPBF and UCC27211D, the AUIRS2113S uniquely combines AEC-Q100 qualification, independent logic supply (V_DD), and edge-triggered shutdown - making it the only option validated for ASIL-B–capable HEV/EV subsystems.

FAQ

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

The AUIRS2113S is specified to tolerate transient voltage changes at the VS pin up to 50 V/ns under recommended operating conditions. This immunity is achieved through proprietary HVIC layout and internal level-shifting design, preventing false turn-on during fast high-side switching in 600 V systems.

Does the AUIRS2113S require external bootstrap diode and capacitor?

Yes - the AUIRS2113S requires an external bootstrap diode and capacitor connected between V_B and V_S to generate the floating supply for the high-side driver. Typical values are a 10–22 nF ceramic capacitor and a fast-recovery 100 V Schottky diode placed adjacent to the IC for minimal loop inductance.

How does the shutdown (SD) pin function?

The SD pin is active-low and edge-triggered: a rising edge forces both HO and LO outputs immediately low and holds them until the next valid HIN/LIN transition. This cycle-by-cycle behavior provides deterministic fault response without latching, supporting ASIL-B diagnostic coverage in automotive safety architectures.

Can V_DD and V_CC be supplied from the same rail?

Yes - V_DD (logic supply) and V_CC (low-side gate supply) may share a common 12 V or 15 V rail if the MCU and gate driver operate at the same voltage. However, separating them allows 3.3 V MCU interfacing while maintaining 15 V gate drive, improving noise isolation and efficiency.
