AUIRS21811STR Description

Short technical summary and product information.

The AUIRS21811STR from Infineon Technologies is a high voltage, high speed power MOSFET and IGBT driver. It features independent high and low side referenced output channels, making it suitable for half-bridge configurations. The device is fully operational to 600V and tolerates negative transient voltage with dV/dt immunity.

Key electrical specifications include a gate drive supply range of 10V to 20V and logic voltage compatibility down to 3.3V. The output drivers provide a typical source current of 1.9A and a sink current of 2.3A. Matched propagation delays and a lower di/dt gate driver enhance noise immunity.

This component is housed in an 8-SOIC package with a surface mount type. It operates within a temperature range of -40°C to 150°C (TJ). The AUIRS21811STR is designed for applications such as electric power steering, fan and compressor control, and starter/alternator systems.
