System Basis Chips (SBC)
The Driver SBC is the first family of the new generation of Infineon SBC in an exposed pad
VQFN-48 (7mm x 7mm) power package. The family offers several variants to meet the different
application requirements. The devices are designed for various CAN-LIN automotive body applications
as a main supply for the micro controller and as an interface for a CAN and LIN bus network
(optional CAN partial networking).
To support these applications, the Driver SBC provides the main functions, such as a 5V low dropout voltage regulator (LDO) for micro controller supply, a 5V low-dropout voltage regulator with short circuit protection against supply voltage VS for e.g. sensor supply, HS-CAN transceiver and LIN transceiver for data transmission, fully protected Low- and High-Side Switches, and a 16-bit Serial Peripheral Interface (SPI) to control and monitor the device.
Also implemented are a Window Watchdog circuit with a reset feature, a Fail Output and an under voltage reset feature. The device offers low-power modes in order to support applications that are connected permanently to the battery.
A wake up from the low-power mode is possible via a message on the buses, via the bi-level sensitive monitoring/wake-up inputs as well as via cyclic wake. The device is designed to withstand the severe conditions of automotive applications.
An evaluation board is available to start the evaluation of the device and accelerate the design-in phase. The demoboard can be connected to the “XC2000 power easy kit” and controlled, via USB, using a powerful and intuitive Graphical User Interface (GUI) installed on your computer.
Additional SBC families will be released in the upcoming months to fulfill the different Automotive ECU requirements. All the SBC families of the new generation offer a software compatibility and, whenever possible, also a hardware compatibility to minimize the effort for software and hardware development.
