Infineon BTS4141NHUMA1 High-Side Power Switch: Features, Applications, and Technical Overview
The Infineon BTS4141NHUMA1 is a robust and highly integrated intelligent high-side power switch designed using advanced PROFET™ (Protected MOSFET) technology. This device is engineered to deliver efficient and reliable power control for a wide range of automotive and industrial applications, combining protection features, diagnostic capabilities, and high performance in a single package.
Key Features
Built with a vertical N-channel power MOSFET, the BTS4141NHUMA1 offers a continuous current rating of up to 180 mA and can handle a load voltage of up to 42 V. Its low on-state resistance (RDS(on)) ensures minimal power dissipation, enhancing energy efficiency and thermal performance. The device incorporates comprehensive protection functions, including over-load and short-circuit protection, over-temperature shutdown, and over-voltage clamp. It also provides diagnostic feedback through a status output pin, enabling real-time monitoring of the switch condition—such as open-load detection in on and off states—which is critical for system reliability and debugging.
Primary Applications
Thanks to its robust design and diagnostic features, the BTS4141NHUMA1 is widely used in automotive systems, such as body control modules, seat and window control units, and other mechatronic applications. It is also suitable for industrial automation, where it drives solenoids, actuators, and small motors. Its ability to operate in harsh electrical environments makes it ideal for 12 V and 24 V DC systems that require safe and intelligent switching.
Technical Overview
Housed in a TO-252-4 (DPAK) package, the device supports reverse battery protection and features very low standby current. The built-in charge pump allows efficient control of the high-side switch with a CMOS-compatible input. Its ESD robustness ensures durability in demanding conditions. The combination of protection mechanisms and diagnostic intelligence simplifies system design while improving safety and longevity.
ICGOOODFIND: The Infineon BTS4141NHUMA1 stands out as a highly reliable and feature-rich high-side switch, offering an optimal blend of performance, integration, and protection for modern electronic systems.
