Infineon BTS5010-1EKA: High-Performance Smart High-Side Power Switch

The Infineon BTS5010-1EKA is a state-of-the-art smart high-side power switch designed to deliver superior performance, reliability, and diagnostic capabilities for a wide range of automotive and industrial applications. As part of Infineon’s PROFET™ (Protected MOSFET) family of products, this device integrates advanced protection features and intelligent control in a compact package, making it an ideal solution for driving resistive or inductive loads such as motors, lamps, and heaters.

One of the standout features of the BTS5010-1EKA is its high current handling capability, supporting continuous currents up to 140 mA with a very low typical on-state resistance (RDS(on)). This ensures minimal power dissipation and high energy efficiency, which is critical for battery-operated systems and applications where thermal management is a concern. The device operates over a broad voltage range, from 5.5 V to 40 V, providing flexibility for 12 V and 24 V DC systems commonly found in automotive environments.

The BTS5010-1EKA excels in providing robust protection and diagnostic functions. It includes built-in safeguards such as overload protection, short-circuit protection, over-temperature shutdown, and over-voltage clamp. These features enhance system reliability by preventing damage under fault conditions. Additionally, the device offers precise current sensing via a dedicated sense pin, enabling real-time load monitoring and diagnostics—key for predictive maintenance and fault detection in modern electronic systems.

Another significant advantage is its enhanced electromagnetic compatibility (EMC) performance, which minimizes electromagnetic interference and ensures stable operation in noisy environments. The device also features a logic-level input compatible with microcontrollers, simplifying interface design and reducing external component count.

Housed in a TO-263-7 (D2PAK) package, the BTS5010-1EKA offers excellent thermal performance and mechanical durability, making it suitable for harsh operating conditions. Its combination of high integration, diagnostic intelligence, and ruggedness positions it as a top choice for applications in body control modules, power distribution units, and industrial automation systems.
