Infineon BTS5235-2G: A Dual Channel Smart High-Side Power Switch

In the realm of automotive and industrial electronics, efficient and reliable power management is paramount. The Infineon BTS5235-2G stands out as a highly integrated solution, engineered to meet the rigorous demands of modern applications. This device is a dual-channel smart high-side power switch fabricated using Infineon’s proprietary Smart SIPMOS technology, offering robust performance, comprehensive diagnostic capabilities, and enhanced protection features in a compact package.

The BTS5235-2G is designed to drive resistive or inductive loads, such as lamps, motors, or solenoids, with each channel capable of handling a continuous current of up to 230 mA. Its integrated design combines two channels with protective and diagnostic functions, making it an ideal choice for reducing system complexity and board space. Key features include overload protection, short-circuit protection, and over-temperature shutdown, which safeguard both the switch and the connected loads from potential damage. Additionally, the device offers reverse battery protection up to -40 V, a critical requirement in automotive environments where voltage transients are common.

One of the most significant advantages of the BTS5235-2G is its diagnostic feedback capability. The status pin provides real-time information on fault conditions, such as open-load detection in both on and off states, short-circuit events, and over-temperature warnings. This enables proactive system maintenance and enhances overall reliability. The device operates with a low standby current and features low quiescent current consumption, making it suitable for battery-powered applications where energy efficiency is crucial.

The BTS5235-2G is housed in a PG-DSO-14 package, ensuring both thermal performance and mechanical durability. Its automotive-grade qualification (AEC-Q100 compliant) underscores its suitability for use in harsh environments, including under-the-hood automotive systems, body control modules, and industrial automation controls.
