The SCT41080Q device is fully protected singlechannel smart high-side switch with four integrated 75mΩ NMOS power FETs. For version A, the device implements the digital fault report with an open-drain structure. For version B, the device achieves high-precision current detection, making diagnosis more accurate. The SCT41080Q provides current limit, thermal shutdown protection. Full diagnostics and highaccuracy current sense enable intelligent control of the load. The device is available in a 14-pin ETSSOP-14 package.
APPLICATIONS：
• High-Side Relay Drivers
• Power Switch for Sub-Module Power Supply
• Low Wattage Lamp Power Switch
• General Resistive, Inductive, and Capacitive Loads
