Overview of BTS4140N

The BTS4140N is a high-side power switch from the automotive computer power systems (CPOS) family designed for industrial applications. It is ideal for driving resistive, capacitive, and inductive loads such as lamps, solenoids, relays, valves, heating elements, motors, and more. This power switch can handle a continuous output current of up to 4.8A and supports short-circuit protection, over-temperature protection, overload protection, and open-load detection. It has a wide input voltage range from 4.75V to 40V, making it suitable for a variety of industrial applications. The BTS4140N is housed in a PG-TO252-5-11 package, which provides a compact and thermally efficient solution. It operates at a temperature range of -40°C to 150°C, ensuring reliable performance in harsh environments. The switch is controlled through a logic-level input signal, making it easy to interface with microcontrollers and other control circuits.
