Infineon BSL316CH6327XTSA1: High-Performance Smart High-Side Switch for Automotive and Industrial Applications
Modern automotive and industrial systems demand robust, efficient, and intelligent power management solutions. The Infineon BSL316CH6327XTSA1 stands out as a premier smart high-side power switch engineered to meet these rigorous requirements. Combining advanced protection features, diagnostic capabilities, and high efficiency in a single package, this device is designed to drive resistive, capacitive, and inductive loads with exceptional reliability.
A key strength of the BSL316CH6327XTSA1 is its integration of three independent channels in a compact PG-TSDSO-14 package. Each channel can handle continuous currents up to 160 mA, with a maximum operating voltage of 42 V, making it suitable for a wide range of 12 V and 24 V systems commonly found in automotive environments. The device is built using Infineon’s proprietary SMART7 technology, which enables precise analog current sensing, load current feedback, and comprehensive diagnostic reporting via a dedicated status output pin.
Protection and reliability are central to its design. The switch features embedded safeguards including over-load and short-circuit protection, over-temperature shutdown, and over-voltage clamp. Crucially, it also provides reverse battery protection down to -18 V, a critical requirement in automotive applications where jump-starting or incorrect battery connection can occur. The open-drain status flag provides real-time feedback on fault conditions such as overtemperature or short circuits, enabling swift system responses to prevent damage.
The device’s efficient operation is underscored by its very low typical on-state resistance (RDS(on)) of just 1.8 Ω per channel. This minimizes power dissipation and reduces heat generation, contributing to higher system efficiency and reliability. Furthermore, its ability to withstand high in-rush currents makes it ideal for controlling lamps, LEDs, or small motors that exhibit high startup current demands.
In application, the BSL316CH6327XTSA1 excels in driving a variety of loads. In the automotive sector, it is perfect for body control modules (BCMs), lighting systems, and comfort electronics. In industrial settings, it reliably manages solenoids, actuators, and PLC output modules. Its compatibility with microcontrollers via a simple logic-level input simplifies design-in, while its diagnostic capabilities support functional safety goals, aligning with standards like ISO 26262.
ICGOOODFIND: The Infineon BSL316CH6327XTSA1 is a highly integrated, robust, and intelligent triple-channel high-side switch. Its blend of advanced protection, detailed diagnostics, and high efficiency makes it an superior solution for enhancing the reliability and performance of modern automotive and industrial power systems.
