Infineon BTS70015-1ESP: A High-Performance Smart High-Side Power Switch

In the rapidly evolving world of automotive, industrial, and consumer electronics, the demand for efficient, reliable, and intelligent power management solutions is higher than ever. The Infineon BTS70015-1ESP stands out as a premier solution, engineered to meet these rigorous demands as a state-of-the-art smart high-side power switch.

This device integrates a plethora of advanced features into a single, compact package. At its core, it boasts a robust 15 mΩ N-channel MOSFET, enabling it to handle high-load currents with exceptional efficiency and minimal power dissipation. This low on-state resistance is crucial for applications where thermal management and energy savings are paramount.

A key differentiator of the BTS70015-1ESP is its integrated smart functionality. It provides comprehensive diagnostic and protection features that are essential for designing resilient systems. These include precise current sensing via a dedicated output pin (IS), which allows for real-time load monitoring without significant power loss. Furthermore, it is equipped with protection against overload conditions, short circuits, and overtemperature, actively shutting down to prevent damage to both itself and the connected load. The inclusion of undervoltage lockout (UVLO) and overvoltage clamp ensures stable operation even in electrically noisy environments, such as automotive power networks.

The device also features a very low standby current, making it ideal for battery-powered applications that require always-on functionality. Its control is simplified through a 3.3 V and 5 V logic-compatible input, allowing for direct interfacing with microcontrollers without the need for additional level-shifting circuitry. Housed in a PG-TO263-7-31 package, it offers an excellent power-to-size ratio and is designed for enhanced thermal performance, facilitating effective heat dissipation.

Typical applications are vast and include but are not limited to: LED lighting modules, solenoid and actuator control, power distribution units, and heavy-duty automotive loads. Its robustness makes it perfectly suited for 12 V and 24 V DC systems common in trucks, industrial machinery, and advanced driver-assistance systems (ADAS).

ICGOOODFIND Summary: The Infineon BTS70015-1ESP is a highly integrated, intelligent power switch that sets a high standard for performance and protection. Its combination of extremely low RDS(on), accurate diagnostics, and a suite of embedded safety features makes it an superior choice for designers seeking to enhance system reliability, efficiency, and intelligence in demanding power control applications.
