INFINEON Smart Power Switch, High Side, 1 Output, 36V 65A, TO-252-5
INFINEON high-side smart power switch (36V, 65A). AEC-Q100 qualified with integrated protection for automotive & industrial applications.
The INFINEON BTS443P is a sophisticated high-side power switch engineered with advanced Smart SIPMOS® chip-on-chip technology. It integrates a robust N-channel vertical power FET with a charge pump, a current-controlled input, and diagnostic feedback featuring load current sense. This design delivers exceptional power management capabilities with built-in intelligence and protection, making it a reliable choice for demanding electronic control applications.
This component excels in providing comprehensive embedded protective functions to ensure operational safety and longevity. These include short-circuit protection, precise current limitation, overload protection, and overvoltage protection. It also safeguards against system-level faults such as loss of ground and loss of Vbb (battery supply). The device is specifically designed to handle challenging loads, including charged inductive loads, while maintaining a very low standby current for energy efficiency. It features fast demagnetisation of inductive loads and is optimised for excellent static electromagnetic compatibility (EMC), minimising interference in sensitive circuits.
Housed in a compact TO-252-5 (DPAK) package, the switch is built for high-performance applications where space, reliability, and thermal management are critical. Its robust construction is qualified to the stringent AEC-Q100 automotive standard, ensuring it meets the high-reliability requirements for use in vehicles and other harsh environments.
Applications
This smart power switch is ideally suited for a wide range of automotive and industrial electronic systems. Key application areas include power management modules, heating, ventilation, and air conditioning (HVAC) controls, and various automotive body electronics and powertrain systems where reliable high-current switching is essential.
