The Infineon BTS71040-4ESA is a Serial Interface Power Controller (SPOC™ +2) designed for automotive applications. It offers integrated protection and diagnosis functions, making it suitable for driving loads up to 3A.
Key electrical specifications include a minimum operating voltage of 3.1V and a maximum of 28V, with 3.3V or 5V compatible logic pins. The device features a low maximum ON-state resistance of 38 mΩ at 150°C and a typical current sense ratio of 2000. Protection features include absolute and dynamic temperature limitation, overcurrent protection with programmable restart control, undervoltage shutdown, and overvoltage protection with external components.
Diagnostic capabilities include proportional load current sensing, open load detection in both ON and OFF states, and short circuit detection to ground and battery. Feedback is provided via a daisy-chain capable SPI interface. The device also incorporates functional safety features like Limp Home mode and input pin status monitoring.
Packaged in a PG-TSDSO-24, this surface-mount component is qualified for automotive applications according to AEC-Q100 Grade 1. It is designed to replace electromechanical relays, fuses, and discrete circuits in various applications.
