Infineon BTS442E2BKSA1: High-Current PROFET™ Smart High-Side Power Switch

In the realm of automotive and industrial electronics, robust and intelligent power management is critical. The Infineon BTS442E2BKSA1 stands out as a premier solution in this space, representing a key member of Infineon’s PROFET™ (PROtected Field Effect Transistor) family of smart high-side power switches. Designed to handle high-current loads up to 37A, this device integrates control, protection, and diagnostic functions into a single compact package, making it ideal for demanding applications.

The BTS442E2BKSA1 is engineered to drive resistive, inductive, and capacitive loads with high efficiency. Its low on-state resistance (typically 6.5 mΩ) ensures minimal power dissipation, which enhances thermal performance and overall system reliability. This feature is particularly valuable in automotive environments, where managing heat in confined spaces is crucial.

A standout attribute of this power switch is its comprehensive suite of built-in protection features. These include protection against overcurrent, overtemperature, short-circuit conditions, and overvoltage events like load-dump. Additionally, the device offers advanced diagnostic capabilities such as current sense feedback, open-load detection, and fault status reporting. These diagnostics allow system controllers to monitor operating conditions in real-time, enabling predictive maintenance and enhancing system safety.

The device is housed in a TO-263-7 package (DPAK), which offers excellent thermal performance and facilitates easy PCB mounting. Its automotive-grade qualification ensures it meets stringent standards for reliability and performance under harsh conditions, making it suitable for a wide range of applications including engine control units, power distribution systems, and heavy-duty motor drives.
