8.2.1 Design Requirements

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.
