BTS70802EPAXUMA1

The Infineon BTS70802EPAXUMA1 is a smart high-side power switch from the PROFET™ +2 12V family, built using SMART7 technology. It provides integrated protection and diagnostic functions, making it suitable for automotive applications. This device is qualified according to AEC-Q100 Grade 1.

Key electrical specifications include a minimum operating voltage of 4.1V and a maximum operating voltage of 28V. It features a maximum ON-state resistance of 39.6 mΩ at 150°C and a nominal load current of 3A at 85°C. The switch also includes overvoltage protection with a clamping voltage of 35V (at TJ ≥ 25°C) and a low sleep mode current of 0.5 µA (at TJ ≤ 85°C).

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 features consist of proportional load current sense, open load detection in ON and OFF states, and short circuit detection to ground and battery.

The BTS70802EPAXUMA1 is housed in a PG-TSDSO-14 package. It is suitable for resistive, inductive, and capacitive loads, and can replace electromechanical relays, fuses, and discrete circuits. The device is capable of driving 3A loads and high inrush current loads, such as P21W lamps or equivalent electronic loads like LED modules.
