Peripheral chip set

The chipset comprises two units. The first unit (1) has a power supply with different output voltages, three sensor supplies, a monitoring module (1g), a driver (1e) for bidirectional serial interfaces, a CAN-driver with wake-up function, a main relay controller (1c, a main relay output stage, a serial peripheral interface (SPI), and a stop/wakeup counter (1d). The second unit (2) includes an eighteen-way power output stage (2a) rated at 0.6 to 3 A, two low-level output stages (2b), and a five-volt monitor (2d). An independent claim is included for an engine control device.
