10.2.1 Design Requirements

Use the following for the design requirements:

  • Power Supplies

    • The device needs 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, it is still possible to use the device, but only with the default settings. Diagnostic information is limited to the discrete reporting FAULT pin.

  • External Components

    • Table 9 lists the components required for the device.
