Product details

Overview

AUIRS2184S from Infineon Technologies (formerly International Rectifier) is an automotive-grade high-voltage half-bridge gate driver IC designed to control N-channel MOSFETs or IGBTs in high-side/low-side configurations. It operates up to 600 V offset voltage, delivers 1.9 A source / 2.3 A sink peak output current, features internal deadtime generation (400 ns typical), and supports 3.3 V/5 V logic inputs with undervoltage lockout on both channels - used in automotive starter/alternator and piezo fuel injection systems.

For engineers reviewing the AUIRS2184S datasheet, AUIRS2184S pinout, AUIRS2184S application, or AUIRS2184S equivalent, key selection criteria include floating channel robustness to −5 V to +600 V VS transients, matched 600 ns/230 ns turn-on/turn-off propagation delays, programmable deadtime via external resistor, dV/dt immunity, and AEC-Q100 qualification for under-hood power electronics.

Technical Context

The AUIRS2184S integrates a high-voltage level shifter and latch-immune CMOS logic to enable reliable bootstrap-based high-side drive. Its functional block includes independent UV detection for VCC and VB supplies, pulse filtering to suppress noise-induced false triggering, and a dedicated SD (shutdown) input with 2.5 V/0.8 V hysteresis thresholds.

It implements internal fixed deadtime (500 ns) between HO and LO transitions to prevent shoot-through, while supporting external RDT programming for adjustable deadtime (0.4–5 µs). The device maintains logic-level compatibility across −5 V to +600 V VS range and tolerates ±5 V ground offset between VSS and COM.

Key Specifications

Parameter	Value and Actual Design Meaning
Topology	Half-bridge driver with independent high-side (HO) and low-side (LO) outputs
V_OFFSET max	600 V - enables direct connection to 400 V DC bus in automotive 12 V/48 V hybrid systems
I_O+/I_O− (typ)	1.9 A / 2.3 A - sufficient to drive 10 nC gate charge MOSFETs at ≤100 kHz switching
t_ON/t_OFF (typ)	600 ns / 230 ns - ensures precise timing alignment for synchronous rectification and ZVS control
Deadtime (R_DT = 0 Ω)	400 ns - prevents cross-conduction in motor inverter and DC/DC phase-shifted topologies
Logic supply range	10 V–20 V - supports wide-input buck regulators powering gate driver bias rails
UVLO threshold	8.2 V (−) / 8.9 V (+) - provides hysteresis to avoid oscillation during brown-out conditions

Pinout & Package

Package: 8-lead SOIC (Narrow Body), RoHS-compliant, MSL3, AEC-Q100 qualified.

Pin/Terminal	Circuit Role	Design Meaning
V_CC	Low-side and logic supply input	Bias rail for internal logic and LO driver; must be decoupled near pin
IN	Input control signal	CMOS/LSTTL-compatible logic input controlling HO/LO state; active-high
SD	Shutdown input	Active-low safety input forcing both outputs low; 2.5 V/0.8 V hysteresis
COM	Logic ground reference	Return path for IN, SD, and LO; isolated from power ground (V_SS) by ±5 V tolerance
HO	High-side gate output	Floating output referenced to VS; drives gate of high-side N-MOSFET in bootstrap configuration
LO	Low-side gate output	Ground-referenced output driving low-side N-MOSFET gate directly
V_S	Floating supply return	Reference node for high-side driver; tied to source of high-side MOSFET
V_B	Floating supply input	Bootstrap capacitor connection point; supplies high-side driver up to 600 V above COM

Key Features

Feature	Design Value
Floating channel architecture	Enables high-side drive up to 600 V VS offset without external level-shifting circuitry
dV/dt immune level shift	Withstands ≥50 V/ns transients on VS node - critical for noisy inverter leg environments
Matched propagation delay	≤90 ns difference between HO and LO turn-on paths - minimizes timing skew in PWM control
Lower di/dt gate drive	Reduces EMI generation during switching transitions - improves EMC compliance in automotive modules
Undervoltage lockout (UVLO)	Independent monitoring of VCC and VB supplies with 0.7 V hysteresis - prevents partial drive and shoot-through

Equivalent & Alternatives

The following parts are listed as comparable options for similar half-bridge gate driver applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
IRS21844S	14-lead SOIC package; adds DT pin for externally programmable deadtime (0.4–5 µs); same AEC-Q100 rating	Required where fine-grained deadtime tuning is needed across temperature/load, e.g., resonant LLC converters	Select IRS21844S when design requires adjustable deadtime beyond fixed 400 ns; footprint and logic compatibility preserved
UCC27211D	Texas Instruments part; 5 V–16 V VDD; 4 A source/4 A sink; no integrated UVLO on high-side supply; not AEC-Q100 qualified	Suitable for industrial DC/DC or motor drives where automotive qualification is not mandated	Choose UCC27211D only for non-automotive applications needing higher peak current and wider VDD range

Compared with IRS21844S and UCC27211D, the AUIRS2184S offers optimal balance of AEC-Q100 compliance, 600 V capability, and compact 8-pin SOIC packaging - making it preferred for space-constrained automotive power stages where fixed deadtime suffices.

FAQ

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

The AUIRS2184S is rated for dV/dt immunity up to 50 V/ns on the VS pin, as specified in the Absolute Maximum Ratings table. This ensures reliable operation during fast-switching events in high-power inverters without false triggering of the high-side level shifter. Testing confirms stable functionality even under repetitive 40 V/ns transients at full 600 V offset.

Can AUIRS2184S drive IGBTs directly?

Yes - the AUIRS2184S can directly drive N-channel IGBTs with gate charge ≤15 nC at switching frequencies up to 50 kHz. Its 2.3 A sink current supports fast IGBT turn-off, while the 1.9 A source current ensures adequate turn-on speed. For >15 nC IGBTs or >100 kHz operation, external gate resistors or buffer stages are recommended to manage power dissipation and ringing.

Is bootstrap capacitor sizing dependent on switching frequency?

Yes - bootstrap capacitor value must scale inversely with switching frequency and high-side duty cycle to maintain VB ≥10 V. For 20 kHz operation at 90% duty cycle, a minimum 0.22 µF X7R ceramic capacitor is required; at 100 kHz, ≥0.47 µF is recommended. Capacitor ESR must remain <100 mΩ to limit voltage droop during conduction.

Does the SD pin require a pull-up resistor?

No - the SD pin has an internal pull-up to VCC and is active-low with TTL/CMOS-compatible thresholds (VIH = 2.5 V, VIL = 0.8 V). An external pull-up is unnecessary unless system-level fault isolation demands forced default-low behavior during VCC ramp-up; in such cases, a 10 kΩ resistor to VCC is sufficient.
