The Driver SBCs Family
The driver SBC is the first family of the new generation of
Infineon SBC in an exposed pad PG-VQFN-48 (7mm x
7mm) power package. The family oers several variants
to meet the dierent application requirements. The
devices are designed for various CAN-LIN automotive body
applications as a main supply for the microcontroller
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 microcontroller
supply, a 5V low-dropout voltage regulator with short
circuit protection against supply voltage V
S
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 oers 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.
