Infineon BTS6144B: A High-Current Power Switch for Demanding Automotive and Industrial Applications

The Infineon BTS6144B represents a significant advancement in the field of high-side power switches, engineered to meet the rigorous demands of both automotive and industrial environments. This intelligent switch integrates a vertical power MOSFET with a sophisticated CMOS control circuit on a single chip, offering a robust and compact solution for controlling high-current loads with precision and protection.

At its core, the BTS6144B is designed to handle a continuous current of up to 32A, making it an ideal choice for driving a wide array of high-power actuators. In the automotive sector, it is perfectly suited for applications such as electric power steering (EPS) systems, engine management modules, and advanced driver-assistance systems (ADAS) that require reliable and efficient power distribution. Its robust design ensures stable operation under the harsh conditions typical of automotive environments, including significant temperature fluctuations and electrical transients.

A key feature of this device is its comprehensive suite of integrated protection functions. These include protection against over-load, short-circuit, over-voltage, and over-temperature conditions. The inclusion of a diagnostic feedback pin with current sense capability is particularly critical. This feature allows for real-time monitoring of the load current, enabling predictive maintenance and immediate system response to any fault conditions, thereby enhancing overall system safety and reliability.

For industrial applications, the BTS6144B excels in controlling heavy-duty solenoids, motors, and heaters. Its very low standby current and high energy efficiency contribute to reduced power consumption in always-on systems. The device's ability to be directly driven by a microcontroller simplifies circuit design, reduces component count, and saves valuable board space.
