The device is 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 To support these applications, the System Basis Chip (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 VS for e.g. sensor supply, HS-CAN transceiver and LIN transceiver for data transmission, Low- and High-Side switches providing protective functions, 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 permanently connected 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. |
