Infineon BTS7012-1EPA: 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, the Infineon BTS7012-1EPA stands out as a premier high-current PROFET™ (Protected FET) smart switch, engineered specifically for the rigorous demands of modern vehicles.

This device integrates a single N-channel vertical power MOSFET with a sophisticated CMOS control chip, creating a compact yet immensely powerful solution. Its primary function is to act as an intelligent switch, capable of driving a wide array of high-current loads—from LED lighting modules and heaters to DC motors and solenoids—with precision and protection.

Key features and benefits include:

High-Current Handling: With a continuous current rating of up to 23 A per channel, it effortlessly manages the substantial power requirements of various automotive actuators.

Advanced Diagnostic and Protection: A cornerstone of the PROFET™ family is its integrated intelligence. The BTS7012-1EPA provides comprehensive diagnostic feedback to the microcontroller, including precise current sense (IS) signals, load open-circuit detection, and over-temperature warnings. It is also fully protected against short-circuits, over-voltage, electrostatic discharge (ESD), and reverse battery conditions, ensuring system longevity and safety.

Enhanced Reliability: Designed for the harsh automotive environment, it operates reliably over a wide temperature range and is qualified according to AEC-Q100 standards. Its robust design minimizes the need for external protective components, simplifying board layout and reducing total system cost.

Efficiency and Control: The device features a very low standby current and low on-state resistance (RDS(on)), which minimizes power dissipation and improves overall system efficiency. Control is achieved via a standard 3.3V/5V logic input, making it simple to interface with modern microcontrollers.

The BTS7012-1EPA is housed in a thermally enhanced PG-TO263-7-31 package, which provides excellent heat dissipation, crucial for maintaining performance under high-load conditions. Its target applications are vast, covering body control modules (BCMs), junction boxes, and any system requiring robust and intelligent power distribution.

ICGOODFIND: The Infineon BTS7012-1EPA PROFET™ smart switch is an exemplary solution for designers building next-generation automotive systems. It masterfully combines high power density, superior diagnostic capabilities, and robust protective features into a single package, enhancing reliability while simplifying design and ensuring safe operation in the challenging automotive electrical landscape.
