Infineon BTS780GP: High-Performance Smart High-Side Power Switch for Automotive and Industrial Applications
The demand for robust, efficient, and intelligent power switching solutions continues to grow across automotive and industrial sectors. Addressing this need, Infineon Technologies introduces the BTS780GP, a high-performance smart high-side power switch designed to deliver superior reliability, precision control, and system integration in demanding environments.
Engineered to excel in 12V and 24V DC systems, the BTS780GP integrates advanced functionalities that simplify design while enhancing protection. Its high-current capability (up to 40A) makes it suitable for a wide range of resistive, inductive, and capacitive loads, such as motors, heaters, and lamps. A key highlight is its extremely low standby current, which is critical for automotive applications where energy efficiency directly impacts battery life and compliance with modern energy standards.
The device incorporates comprehensive diagnostic and protection features, ensuring safe operation under fault conditions. These include overload protection, short-circuit protection, overtemperature shutdown, and overvoltage clamping. Additionally, the current sense pin provides a proportional load current feedback signal, enabling precise monitoring without external shunts—a significant advantage for closed-loop control systems.
The BTS780GP also supports reverse battery protection through its integrated body diode, safeguarding the system from incorrect polarity connections. Its ESD robustness and low electromagnetic emission (EME) characteristics further ensure compliance with stringent automotive and industrial electromagnetic compatibility (EMC) requirements.
With its compact PG-DSO-12 package, the BTS780GP offers excellent thermal performance and power density, making it ideal for space-constrained applications. Its combination of high switching performance, diagnostic intelligence, and ruggedness positions it as a versatile solution for modern power management challenges.
The Infineon BTS780GP stands out as a highly integrated, intelligent power switch that merges high current handling with advanced diagnostics and protection. It is an optimal choice for designers seeking to improve system efficiency, reliability, and miniaturization in automotive and industrial power systems.
