Infineon released Driver SBC is the first family in a new generation of System Basis Chips (SBS) from Infineon. It is a monolithic integrated circuit in an exposed pad VQFN-48 (7mm × 7mm) power package. This new family includes several variants to suit all application needs.
The Driver SBC is designed to function as a main supply for the microcontroller and an interface for a CAN-LIN bus network (supporting CAN partial networking if required) in various CAN-LIN automotive body applications. The feature set includes a 5V low-dropout voltage regulator (LDO) to supply the microcontroller, a 5V low-dropout voltage regulator with short-circuit protection against supply voltage (Vs) to supply the sensor, a HS CAN transceiver and LIN transceiver for data transmission, fully protected low- and high-side switches and a 16-bit serial peripheral interface (SPI) for device monitoring and control.
Driver SBC also comes with a window watchdog circuit with a reset feature as well as a fail output and an undervoltage reset feature. The device features low-power modes for applications that are permanently connected to a battery. It can be woken up from low-power mode by means of a bus message, bi-level sensitive monitoring/wake-up inputs or a cyclic wake function. Driver SBC is designed to withstand the harsh automotive environment.
A demo board is available to simplify device evaluation and speed up the design-in phase. The demo board can be connected to the “XC2000 power easy kit” and controlled via USB using a powerful and intuitive graphical user interface (GUI) installed on a computer.
Additional SBC families will be released in the upcoming months to fulfill different automotive ECU requirements. All SBC families in this new generation are software-compatible and, whenever possible, hardware-compatible to reduce the effort involved in software and hardware development.
