The Infineon Technologies BTS409L1 is a monolithic N-channel vertical power FET integrated into a Smart SIPMOS technology. It functions as a 12V and 24V compatible power switch with diagnostic feedback, suitable for various DC grounded loads. This device replaces traditional electromechanical relays, fuses, and discrete circuits.
Key electrical specifications include an operating voltage range of 5.0V to 34V, a maximum output current of 1.8A, and a typical on-state resistance of 160mOhm. The BTS409L1 incorporates comprehensive protection functions such as overload protection, current limitation (fixed at 4A), short circuit protection, thermal shutdown, and overvoltage protection (up to 43V). It also features open load detection in the ON-state and reverse battery protection.
Designed for ease of integration, the BTS409L1 has a CMOS compatible input and an open-drain diagnostic output (ST) that signals failures. It is housed in a TO-220-5 package suitable for through-hole mounting. The operating temperature range is -40°C to +150°C (TJ), making it suitable for demanding environments. This AEC qualified component is ideal for automotive applications and general-purpose power switching.
Applications include µC compatible power switching with diagnostic feedback for 12V and 24V DC grounded loads, and driving all types of resistive, inductive, and capacitive loads. Its integrated protection and diagnostic capabilities simplify system design and enhance reliability.
