Infineon BTS70802-2EPAXUMA1: A High-Current PROFET™ Smart High-Side Switch for Demanding Automotive and Industrial Applications
The Infineon BTS70802-2EPAXUMA1 represents a significant advancement in power management technology, integrating robust protection, diagnostic capabilities, and high-current handling into a single, compact package. As part of Infineon's PROFET™ (Protected MOSFET) family of smart high-side switches, this device is engineered to drive resistive, capacitive, and inductive loads with exceptional reliability, making it a cornerstone for modern electronic systems in automotive and industrial environments.
At its core, the BTS70802-2EPAXUMA1 is a dual-channel smart switch, each channel capable of continuously handling up to 8 A. Its high-side configuration simplifies design by connecting the load between the switch output and ground, reducing wiring complexity and enhancing safety. The device operates from a wide supply voltage range of 5.5 V to 40 V, ensuring compatibility with 12 V and 24 V battery systems commonly found in vehicles and machinery, even under challenging conditions like load-dump events.
A key feature of this PROFET™ switch is its intelligent diagnostic and protection suite. It provides real-time feedback to a microcontroller on critical parameters such as load current (via a proportional current sense pin), output short to ground or battery, and overtemperature conditions. This allows for predictive maintenance and immediate system response to faults. Integrated protections include overcurrent limitation, overtemperature shutdown with automatic restart, and overvoltage clamp, safeguarding both the switch and the connected load from damage.
The device is housed in a thermally enhanced PG-DSO-20 EP package, which offers a very low RDS(on) of just 18 mΩ per channel. This high efficiency minimizes power dissipation, reduces heat generation, and eliminates the need for an external heatsink in most applications, saving valuable board space and lowering the total system cost.
Typical applications are extensive, ranging from automotive body electronics (e.g., seat heaters, window lifters, sunroof controls) to industrial automation systems (controlling solenoids, valves, and small motors). Its AEC-Q100 qualification ensures it meets the stringent reliability standards required for automotive use.
ICGOOODFIND: The Infineon BTS70802-2EPAXUMA1 PROFET™ Smart High-Side Switch stands out as a highly integrated, robust, and intelligent solution for high-current switching. Its combination of dual-channel high-current capability, comprehensive diagnostic feedback, and robust built-in protection makes it an superior choice for designers seeking to enhance system reliability, safety, and efficiency in demanding environments.
