Use the following for the design requirements:

• Power supplies

  The device requires only a single power supply compliant with the recommended operation range. The device is designed to work with either a vehicle battery or regulated power supply such as from a backup battery.

• Communication

  The device communicates with the system controller with both discrete hardware control pins and with I²C. The device is an I²C slave and thus requires a master. If a master I²C-compliant device is not present in the system, the device can still be used, but only with the default settings. Diagnostic information is limited to the discrete reporting FAULT pin.

• External components

  Table 8-1 lists the components required for the device.
