Product details

Overview

AUIRS2003S 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 with floating channel up to +200V offset, supports 10–20V gate drive supply, delivers 290mA high-side and 600mA low-side peak output current, and features internal deadtime (520ns typ.) for shoot-through prevention-used in pre-charge switch drives and DC-DC converters.

For engineers reviewing the AUIRS2003S datasheet, AUIRS2003S pinout, AUIRS2003S application, or AUIRS2003S equivalent, key selection criteria include its AEC-Q100 qualification, dV/dt immunity, matched propagation delays (680ns/150ns), 3.3V/5V/15V logic compatibility, and SOIC-8N package with bootstrap-enabled high-side drive capability.

Technical Context

The AUIRS2003S integrates a high-voltage level shifter and latch-immune CMOS logic to enable robust floating-channel operation up to 200V VS offset. Its internal deadtime generator and cross-conduction prevention logic ensure safe complementary switching between HO and LO outputs.

It features independent undervoltage lockout on VCC (8.2V threshold) and bootstrap supply monitoring, with logic inputs tolerant to -5V to +200V VS transients. Propagation delays are tightly matched (≤60ns skew) between channels, and output rise/fall times are specified at 70ns/35ns (typ.) under 1000pF load.

Key Specifications

Parameter	Value and Actual Design Meaning
Topology	Half-bridge driver with independent high-side and low-side outputs
V_OFFSET max	200V - enables direct control of high-side N-MOSFETs in buck, half-bridge, or pre-charge circuits
I_O+/I_O− (peak)	290mA / 600mA - sufficient to rapidly charge/discharge gate capacitance of medium-power MOSFETs
t_ON/t_OFF (typ.)	680ns / 150ns - ensures precise timing control and minimal overlap in PWM-driven topologies
Deadtime (typ.)	520ns - hardwired internal delay prevents simultaneous conduction of high- and low-side switches
Logic compatibility	3.3V, 5V, and 15V CMOS/LSTTL - simplifies interface with microcontrollers, DSPs, and FPGA PWM generators
Qualification	AEC-Q100 Grade 0 (−40°C to +125°C ambient) - validated for under-hood automotive power systems

Internal deadtime insertion	520ns typ. fixed delay prevents shoot-through during HO/LO transition without external timing components
Matched propagation delay	≤60ns skew between HO and LO paths ensures symmetrical PWM edge alignment
Undervoltage lockout (UVLO)	Independent UVLO on V_CC (8.2V threshold) and bootstrap supply prevents erratic switching during brownout

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
IRS2003S	Industrial-grade version; same pinout and electrical specs but not AEC-Q100 qualified	Lacks automotive temperature range (−40°C to +125°C) and qualification test reporting	Select when cost-sensitive non-automotive designs require identical functionality without qualification overhead
IR2103S	Lower V_OFFSET (600V vs. 200V), no internal deadtime, requires external timing network	Used in higher-voltage industrial inverters where bootstrap stability at 200V is not required	Choose only if system VS swing exceeds 200V and external deadtime control is acceptable

Compared with IRS2003S and IR2103S, the AUIRS2003S uniquely combines automotive qualification, integrated 520ns deadtime, and guaranteed 200V dV/dt immunity-making it the sole choice for AEC-Q100-compliant pre-charge and EPS auxiliary supply designs where timing precision and transient robustness are non-negotiable.

FAQ

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

The AUIRS2003S is rated for up to 50 V/ns dV/dt on the VS pin under all operating conditions. This specification is verified per AEC-Q100 stress testing and ensures reliable operation during fast-switching transients in motor drive and converter applications without false triggering or latch-up.

Can the AUIRS2003S drive both MOSFETs and IGBTs?

Yes-the AUIRS2003S is explicitly characterized to drive both N-channel power MOSFETs and IGBTs. Its 290mA high-side source and 600mA low-side sink currents meet gate drive requirements for devices up to ~50A I_LOAD in typical automotive half-bridge configurations.

Is an external bootstrap diode required?

Yes-a fast recovery or Schottky bootstrap diode (e.g., 1N4148W or equivalent) must be placed between V_CC and V_B to charge the bootstrap capacitor during LO conduction. The AUIRS2003S does not integrate this diode; omission will cause high-side drive failure after initial startup.

Does the AUIRS2003S support 3.3V-only microcontroller interfaces?

Yes-its logic inputs (HIN/LIN) are fully compatible with 3.3V CMOS levels, with VIH(min) = 2.5V at V_CC ≥ 10V. No level-shifting circuitry is needed when interfacing directly with 3.3V MCUs such as Infineon's AURIX™ or STMicroelectronics' SPC5 series.
