8 High-Current PROFET High-Current PROFET Current-Controlled First generation of low-ohmic smart power switches The High-Current (HiC) PROFET is a low-ohmic PROFET (PROtected FET) suitable for use in heating systems. Housed in different types of packages, these devices are single-channel high-side switches, assembled in chip-on-chip technology.

10 High-Current PROFET High-Current PROFET Voltage-Controlled BTS500x0-1EGA Scalable 5-8mΩ smart high-side switches family The current-controlled High-Current PROFET needs an external small signal transistor connected at the input (IN) pin to switch the current which turns the device on and off The latest High-Current PROFET devices are voltage-controlled. The input (IN) pin, which is COS-compatible, can be connected directly to a microcontroller, thereby reducing the external circuitry necessary to drive the device The first group of voltage-controlled devices is the BTS 500x0-1EGA family. It consists of four switches, with R DS(on) ranging from 5 to 8mΩ. Assembled in the same package (PG-DSO-12), the switches are pin and functionally compatible with each other and are scalable by R DS(on) and related parameters The products scalability offers great design flexibility the same board layout can be used for different loads, with minimum software changes In addition to the protection and diagnostic feature set embedded in the previous generation of High-Current PROFET, the BTS 500x0-1EGA family comes with Infineon Enhanced Sense, which improves the diagnostic capability on the current sense (IS) pin and has the potential to support open load and short-to-battery detection in the OFF state The DEN (Diagnostic ENable) pin enables the multiplexing of the diagnostic signal, as well as a reduction of the stand-by current Key Features Scalability by RDS(on) Pin, package and functionally compatible products Voltage-controlled with 3.3 and 5V COS-compatible inputs Benefits Simplified board design and layout; reduced qualification and software complexity; easy implementation of fallback solution Can be connected directly to a microcontroller ReverSave Reduced power dissipation in reverse battery condition Supports a multiplexed current sense signal One A/D converter shared among several devices Embedded protection features (e.g. latched overcurrent shutdown, latched overtemperature shutdown) Protection of both the load and the device Defined fault signal via sense pin (Infineon Enhanced Sense) AEC-qualified green packages (RoHS-compliant) Easy failure type detection via direct connection to the microcontroller Suitable for lead-free soldering in accordance with IPC/JEDEC J-STD
