Infineon BTS7002-1EPP: High-Current PROFET™ Smart Switch for Robust Automotive Applications

The increasing complexity of automotive electrical systems demands highly reliable, intelligent, and robust power management solutions. Addressing this need, Infineon Technologies introduces the BTS7002-1EPP, a second-generation High-Current PROFET™ (Protected MOSFET) smart switch designed to set a new benchmark for performance and durability in the most demanding automotive environments.

This single-channel high-side switch is engineered to control a wide range of resistive, capacitive, and inductive loads, such as heaters, motors, and LEDs, with a continuous current capability of up to 23 A. Its core strength lies in its exceptional level of integration, which consolidates protective functions that would traditionally require numerous discrete components. This not only simplifies board design but also enhances overall system reliability.

Key features that define the BTS7002-1EPP include:

Advanced Protection Mechanisms: The device is equipped with a comprehensive suite of built-in protective features, including protection against overload, short-circuit, over-voltage, and over-temperature. This ensures safe operation under fault conditions, preventing damage to both the switch and the load it controls.

Precise Diagnostic Feedback: A critical advantage for modern electronic control units (ECUs) is the detailed diagnostic information provided via the IS (sense) pin. This feature allows for real-time monitoring of the load current, detection of open-load conditions, and indication of overtemperature and short-circuit events, enabling predictive maintenance and enhanced system control.

Optimized Electromagnetic Compatibility (EMC): Designed to meet stringent automotive EMC requirements, the BTS7002-1EPP minimizes electromagnetic emissions, ensuring it does not interfere with other sensitive electronics in the vehicle.

Robustness and Quality: As an automotive-grade component, it is qualified in accordance with AEC-Q100. It offers very low standby current and is designed to handle harsh electrical transients, such as those described in the ISO 7637-2 standard, including load dump pulses.

The BTS7002-1EPP is particularly suited for a vast array of applications within the vehicle body domain, including sunroof control, window lifters, seat control modules, and various other comfort and convenience functions. Its high level of integration and diagnostic capabilities makes it an ideal choice for designers aiming to reduce system size, weight, and cost while simultaneously improving functionality and safety.
