System Basis Chips

タイトルまたは説明

The devices of the SBC family are monolithic integrated circuits in an enhanced power package with identical software functionality and hardware features except for the number of LIN cells and the number of Limp Home Outputs. The devices are designed for CAN-LIN automotive applications e.g. body controller, gateway applications. To support these applications, the System Basis Chip (SBC) provides the main functions, such as HS-CAN transceiver for data transmission, low dropout voltage regulators (LDO) for an external 5 V supply, and a **-bit Serial Peripheral Interface (SPI) to control and monitor the device. Also implemented are a Time-out or a Window Watchdog circuit with a reset feature, Limp Home circuitry output, and an undervoltage reset feature. The devices offer low power modes in order to support application that are connected permanent to the battery. A wake-up from the low power mode is possible via a message on the buses or via the bi-level sensitive monitoring/wake-up as well as from the SPI command. Each wake-up source can be inhibited. The device is designed to withstand the severe conditions of automotive applications.
