AUIRS21271STR Description

Short technical summary and product information.

The AUIRS21271STR by Infineon Technologies is a high-voltage, high-speed power MOSFET and IGBT driver. It is designed for high-side or low-side configurations and operates up to 600V.

 

Key electrical specifications include a gate drive range of 9V to 20V for automotive applications, with output currents of 290mA and 600mA. It offers a fast turn-on time of 200ns and turn-off time of 175ns.

 

This driver is housed in an 8-SOIC package suitable for surface mounting. It includes features like undervoltage lockout and desaturation over-current protection, indicated by a FAULT lead.

 

Typical applications include motor drives for forklifts, hydraulic pumps, and general-purpose three-phase inverters requiring IGBT drive with desaturation detection.
