BTS5010-1E Automotive Single High-Side Power Switch for BCM, Headlamps & Lighting Control (DSO-14)
The BTS5010-1E is a single-channel smart high-side power switch engineered for demanding automotive body control applications. This chip is specifically designed for body control modules (BCMs) to drive high-power lighting loads including H4/H7 headlamps, as well as LED arrays, in the harsh automotive environment. It serves as a critical component in modern vehicle electrical systems, providing reliable switching and protection for exterior lighting functions.
This driver IC is housed in a compact PG-DSO-14 package with an exposed pad for superior thermal dissipation. The device operates across a wide automotive voltage range of 5V to 28V, making it suitable for 12V electrical architectures. Its robust design ensures reliable performance under extreme temperature conditions from -40°C to 150°C typical of vehicle applications. The output channel features a very low on-resistance of 16 mΩ, minimizing power losses and heat generation during operation.
The BTS5010-1E is built on advanced Smart6 technology, featuring an N-channel vertical power MOSFET with charge pump. It integrates comprehensive protection features to ensure long-term durability, including over-temperature protection, over-current protection, and short-circuit protection. The chip also provides electrostatic discharge (ESD) protection on all pins. The logic ground is independent from the load ground, simplifying system design and improving noise immunity.
The device features logic-level inputs compatible with 3.3V and 5V microcontrollers, simplifying system integration without requiring external level shifters. The chip's very low standby current helps preserve battery life during ignition-off periods. Its optimized switching characteristics reduce electromagnetic interference, easing compliance with automotive EMC standards. The BTS5010-1E is AEC-Q100 qualified, meeting stringent reliability requirements for automotive-grade components.
This single-channel driver is widely used as a direct replacement part for failed headlamp and lighting driver circuits on body computer boards in European and American vehicle models. It is equally suitable for OEM manufacturing, professional repair services, and aftermarket upgrades. The BTS5010-1E simplifies BCM designs by integrating high-power switching into a single compact package, reducing board space and component count.
