Infineon BTS70082EPAXUMA1: High-Performance Intelligent High-Side Power Switch
In the realm of automotive, industrial, and consumer electronics, the demand for robust, efficient, and intelligent power management solutions is ever-increasing. Addressing this need, the Infineon BTS70082EPAXUMA1 stands out as a premier high-performance intelligent high-side power switch. This device integrates advanced functionalities that are critical for modern electronic systems, offering a blend of power, protection, and diagnostic capabilities in a single package.
The BTS70082-2EPA is a dual-channel high-side switch based on Infineon's proven Smart High-Side (SHS) technology. Each channel can deliver a continuous current of up to 420 mA, making it suitable for driving a wide array of loads, including LEDs, solenoids, motors, and resistive elements. Its construction using p-channel power MOSFETs ensures low standby current and high efficiency, which is paramount for battery-operated applications where energy conservation is crucial.
A key hallmark of this device is its comprehensive suite of integrated protection features. These include overload protection, short-circuit protection, overtemperature shutdown, and overvoltage protection (including load-dump resilience). These safeguards not only ensure the longevity and reliability of the switch itself but also protect the connected load and the broader system from potential damage due to fault conditions. The overtemperature protection is particularly sophisticated, utilizing a precise temperature sensor to shut down the device before critical junction temperatures are reached, automatically restarting once it has cooled down.
Furthermore, the BTS70082EPAXUMA1 excels in its diagnostic and control intelligence. It provides proportional load current sense feedback for each channel, allowing a microcontroller to monitor the operational status and health of the connected load in real-time. This enables the detection of open-load conditions (both in on and off-state) and short circuits to ground or battery, facilitating predictive maintenance and enhancing system safety. The very low current consumption in the off-state is a critical feature for applications requiring minimal quiescent current, such as in always-on systems.
The device operates from a wide supply voltage range of 3 V to 40 V, making it exceptionally versatile for 12 V and 24 V automotive systems, as well as various industrial environments. It is housed in a PG-DSO-14-47 EP package, which offers excellent thermal performance and is designed for surface-mount assembly, catering to the industry's trend towards miniaturization.
ICGOOODFIND: The Infineon BTS70082EPAXUMA1 is a superior solution for designers seeking a reliable, feature-rich, and intelligent power switch. Its robust integration of power handling, advanced protection mechanisms, and detailed diagnostic feedback makes it an ideal choice for enhancing system reliability and intelligence in demanding automotive and industrial applications.
