Infineon BTS6143DAUMA1 High-Current PROFET™ Smart High-Side Power Switch

The Infineon BTS6143DAUMA1 is a state-of-the-art high-current PROFET™ (Protected FET) smart high-side power switch designed to deliver robust performance and advanced protection features for demanding automotive and industrial applications. As a key component in modern electronic systems, it integrates a vertical power MOSFET with comprehensive monitoring and safeguarding functionalities, enabling efficient control of high-current loads such as motors, heaters, and lamps with minimal external components.

One of the standout features of the BTS6143DAUMA1 is its high current handling capability, supporting continuous currents up to 32 A. This makes it suitable for applications requiring substantial power delivery while maintaining operational stability. The device operates with a low on-state resistance (RDS(on)), which minimizes power losses and improves overall system efficiency, reducing heat generation and enhancing reliability.

The PROFET™ technology incorporates multiple advanced diagnostic and protection mechanisms, including overcurrent protection, overtemperature shutdown, and overvoltage clamp. These features ensure safe operation under fault conditions, preventing damage to both the switch and the connected load. Additionally, the device offers precise current sensing with a proportional output pin, allowing for real-time load monitoring without disrupting the main current path. This is particularly valuable for systems implementing predictive maintenance or fault detection algorithms.

Designed for automotive environments, the BTS6143DAUMA1 complies with stringent industry standards, offering high immunity to electrostatic discharge (ESD) and transient voltage spikes. Its ability to operate in harsh conditions makes it ideal for use in body control modules, powertrain systems, and other critical vehicle functions. The device also features a reverse battery protection capability, safeguarding the circuit against accidental reverse polarity connection.

With its compact PG-DSO-14 package, the BTS6143DAUMA1 provides a space-efficient solution without compromising performance. The integration of protection and diagnostic functions simplifies PCB design and reduces bill-of-material costs, offering engineers a reliable and cost-effective power management solution.
