Infineon BTS4160DGA: High-Side Smart Power Switch for Automotive and Industrial Applications

The Infineon BTS4160DGA is a robust and highly integrated high-side power switch designed to meet the demanding requirements of automotive and industrial applications. Manufactured using Infineon’s proprietary Smart SIPMOS technology, this device combines a vertical power MOSFET with advanced protection and diagnostic features in a single package. Its ability to handle high currents—up to 22 A continuous current—with very low typical on-state resistance (RDS(on) of just 16 mΩ, makes it exceptionally efficient, minimizing power losses and thermal stress in systems such as automotive body controllers, power distribution units, and industrial automation modules.

One of the key strengths of the BTS4160DGA is its comprehensive suite of embedded protection functions. These include protection against overload, short-circuit, over-temperature, and over-voltage conditions, enhancing system reliability and safety. The device also features reverse battery protection with a clamping circuit, which is critical in automotive environments where polarity reversals can occur during maintenance or jump-start events. Additionally, its current sense pin provides a proportional load current measurement, enabling precise diagnostics and control without the need for external shunt resistors.

The SO-8 package offers both compactness and excellent thermal performance, suitable for space-constrained applications. Diagnostic feedback via the status output pin allows for real-time fault monitoring, supporting predictive maintenance and system health checks. With its wide operating voltage range (up to 28 V) and AEC-Q101 qualification, the BTS4160DGA is engineered to perform reliably under harsh conditions, including significant temperature fluctuations and electrical transients.

ICGOO FIND: The Infineon BTS4160DGA stands out as a versatile and robust high-side switch, offering high efficiency, advanced protection, and diagnostic capabilities tailored for challenging automotive and industrial environments.
