Infineon BTS50902EKAXUMA1: High-Side Power Switch for Automotive and Industrial Applications
The demand for robust, efficient, and intelligent power switching solutions continues to grow across the automotive and industrial sectors. Addressing this need, Infineon Technologies introduces the BTS50902EKAXUMA1, a state-of-the-art high-side power switch engineered to deliver superior performance in demanding environments. This device exemplifies the integration of power, protection, and intelligence into a single compact package, providing system designers with a reliable and efficient solution for controlling a wide range of resistive, capacitive, and inductive loads.
As a PROFET™ (Protected MOSFET) device, the BTS50902EKAXUMA1 is designed to handle high-load current switching up to 7.5 A from a standard logic-level signal provided by a microcontroller. Its core is built upon a vertical N-channel power MOSFET, which offers a very low typical on-state resistance (RDS(on)) of just 50 mΩ. This low resistance is critical for minimizing conduction losses, leading to higher system efficiency and reduced heat generation, which in turn allows for more compact designs with less need for large heat sinks.
A key strength of this power switch lies in its comprehensive suite of embedded protection and diagnostic features. These are essential for ensuring operational safety and reliability, particularly in automotive applications where conditions can be harsh and unpredictable. The device includes protection against overload, short-circuit, and overtemperature conditions. Furthermore, it offers advanced diagnostics such as current sense feedback with a proportional (KILIS) output pin, which allows the microcontroller to monitor the load current accurately. It also provides status feedback for open-load detection (both in on and off-state) and overtemperature warnings, enabling predictive maintenance and swift fault response.
The BTS50902EKAXUMA1 is particularly suited for a vast array of applications. In the automotive domain, it is ideal for driving various loads, including body control modules (e.g., seat heaters, window lifters, lighting systems) and powertrain systems. Its robust design ensures compliance with stringent automotive standards. In the industrial sphere, it finds use in PLCs (Programmable Logic Controllers), motor controls, and actuator drives, where its diagnostic capabilities contribute to higher system uptime and safety.
Packaged in a PG-TDSO-14-3 (SSOP14), the device offers a small footprint while still effectively dissipating heat. Its ability to be controlled directly by a microcontroller simplifies circuit design and reduces the total component count, contributing to lower overall system costs and enhanced reliability.
ICGOOODFIND: The Infineon BTS50902EKAXUMA1 stands out as a highly integrated and intelligent high-side switch. Its combination of low power dissipation, robust protective features, and detailed diagnostic capabilities makes it an exceptional choice for designers seeking to build more efficient, safe, and reliable automotive and industrial systems.
