Intelligent power switch delivers current sensing in auto Apps
INTERNATIONAL RECTIFIER AUIR331x family of high-side intelligent power switch (IPS) devices with accurate current-sensing and built-in protection circuits for automotive applications. The current-sensing accuracy, particularly at low current, enables precise monitoring of load current in order to provide additional data to the microcontroller for diagnostic applications. Typical examples include open-load detection, early warning of overload conditions or stall motor condition. In addition, the AUIR3316S provides a slow-switching version of the AUIR3313S, which helps minimize noise in EMI-sensitive automotive applications.
