Infineon BTS5200-1ENA: High-Side Power Switch with Diagnostic and Protection Features
The Infineon BTS5200-1ENA is a state-of-the-art high-side power switch engineered for robust performance in demanding automotive and industrial applications. As part of Infineon’s PROFET™ (Protected MOSFET) family of smart high-side switches, this device integrates a low-RDS(on) N-channel power MOSFET with advanced protection, diagnostic, and control features into a single compact package. It is designed to efficiently drive resistive, inductive, and capacitive loads—such as motors, valves, heaters, or lamps—with exceptional reliability and intelligence.
A key strength of the BTS5200-1ENA lies in its comprehensive suite of diagnostic and protection features. These include protection against overload, short-circuit, over-temperature, and over-voltage conditions, ensuring the switch and the connected load operate safely even under harsh electrical conditions. The device also provides precise current sense and diagnostic feedback via a dedicated analog sense pin (IS), which delivers a current proportional to the load current. This allows the microcontroller to monitor the status of the load in real-time, enabling detection of faults such as open loads, short-to-ground, or overtemperature shutdown.
The integration of these features significantly enhances system reliability while reducing both design complexity and board space. Operating with a wide supply voltage range and housed in a space-saving PG-SSO-4-1 (TO-252) package, the BTS5200-1ENA is an ideal solution for 12V or 24V DC systems where precision control, diagnostics, and robust protection are critical.
