BTS7040-1EPA Description

Short technical summary and product information.

The Infineon BTS7040-1EPA is a smart high-side power switch featuring integrated protection and diagnostic functions. It is part of the PROFET™ +2 12V family and is suitable for resistive, inductive, and capacitive loads.

This device is designed to replace electromechanical relays, fuses, and discrete circuits. It can drive loads up to 4.5A and handle high inrush currents, making it suitable for applications like P27W + R5W lamps or equivalent electronic loads such as LED modules. The switch operates within a voltage range of 3.1V to 28V, with a minimum operating voltage of 4.1V at switch ON.

Key protection features include absolute and dynamic temperature limitation with controlled restart, overcurrent protection with intelligent 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.

The BTS7040-1EPA is qualified for automotive applications according to AEC-Q100 Grade 1. It comes in a PG-TSDSO-14 package.
