Infineon BTT6200-1ENA: High-Side Switch for Automotive and Industrial Applications
The Infineon BTT6200-1ENA is a highly integrated, protected single-channel high-side switch designed to meet the rigorous demands of automotive and industrial applications. Manufactured using Infineon’s proprietary Smart Power Technology (SPT), this device combines robust performance with diagnostic intelligence, making it an ideal solution for driving resistive, inductive, and capacitive loads such as valves, motors, lamps, or heaters.
A standout feature of the BTT6200-1ENA is its exceptional diagnostic and protection capabilities. The device offers comprehensive feedback through a proportional load current sense pin, enabling precise real-time monitoring of the output current. This is critical for detecting faults such as short circuits, overloads, and open loads—even when the switch is off. Built-in protections include overload current limitation, active short-circuit protection, and over-temperature shutdown, which ensure reliable operation and enhance system longevity by preventing catastrophic failures.
The device operates with a wide supply voltage range from 5.5 V to 40 V, accommodating load-dump conditions common in automotive environments. Its very low standby current and minimized electromagnetic interference (EMI) make it suitable for energy-efficient and noise-sensitive applications. Additionally, the BTT6200-1ENA is AEC-Q100 qualified, guaranteeing its performance and reliability under the extreme temperatures and harsh conditions typical of automotive electronics.
With a low on-state resistance (RDS(on)), the switch minimizes power dissipation, improving overall system efficiency. The inclusion of an enable pin and a diagnosis pin allows for straightforward interfacing with microcontrollers, facilitating smarter power management and system diagnostics.
In industrial settings, the BTT6200-1ENA can be used in PLCs, factory automation systems, and power distribution units, where its robustness and diagnostic features help reduce maintenance costs and downtime.
The Infineon BTT6200-1ENA sets a high standard for high-side power switches, offering a rare blend of durability, diagnostic intelligence, and efficiency—perfect for modern automotive and industrial systems where reliability is non-negotiable.
