AUIRS2003S

Gate Driver Overview

The AUIRS2003S is an automotive-grade, high-voltage half-bridge gate driver IC designed for driving power MOSFETs and IGBTs. It features a voltage class of 600 V with functional level-shift isolation. The device provides independent high-side and low-side reference outputs. Key electrical parameters include a supply voltage range (VCC) of 10 V to 20 V, a source output current of 0.2 A, and a sink output current of 0.35 A. Propagation delays are specified as 220 ns for turn-on and 200 ns for turn-off. Undervoltage lockout thresholds are set at 4.1 V (On) and 3.8 V (Off) for the bootstrap supply (VBS), and 8.9 V (On) and 8.2 V (Off) for the main supply (VCC).

Gate Driver Feature Summary

• Automotive qualification ensuring reliability in harsh environments.
• Integrated bootstrap functionality for high-side drive support.
• Independent high-side and low-side reference outputs.

Gate Driver Applications

• High-voltage motor control systems.
• Industrial power conversion stages.
• Inverter bridge circuits.

Gate Driver Procurement Notes

Verify the specific suffix 'A' indicates automotive grade compliance when sourcing. Confirm package integrity for the 8-Lead SOIC form factor. Ensure documentation matches the official Infineon datasheet specifications for UVLO and delay times. Cross-reference part numbers to distinguish from non-automotive variants like IRS2003S.

Gate Driver Selection Notes

Select this component for applications requiring 600 V blocking capability with automotive reliability standards. The 0.2 A source and 0.35 A sink currents suit moderate gate charge requirements. Verify that the control logic levels align with the 10 V to 20 V VCC operating range. Consider thermal dissipation limits of 625 mW during design.

Gate Driver Part Context

The AUIRS2003S belongs to Infineon's high-voltage gate driver family, specifically tailored for automotive and industrial markets. It serves as the automotive-qualified counterpart to standard industrial drivers, offering identical functional topology but with enhanced durability and certification for vehicle-grade environments.

Gate Driver Replacement Considerations

The IRS2003S is a non-automotive equivalent with similar electrical characteristics. Substitution requires verifying that automotive qualification is not mandatory for the target application. Check pin compatibility and ensure UVLO thresholds meet system startup requirements.
