9.3.10 Power Supply

The device has three power supply inputs, VDD, PVDD, and VBAT, which are described as follows:

    VDDThis pin is a 3.3V supply pin that provides power to the low voltage circuitry.
    VBATThis pin is a higher voltage supply that can be connected to the vehicle battery or the regulated voltage rail in a boosted system within the recommended limits. For best performance, this rail should be 10 V or higher. See the Recommended Operating Conditions table for the maximum supply voltage. This supply rail is used for higher voltage analog circuits but not the output FETs.
    PVDDThis pin is a high-voltage supply that can either be connected to the vehicle battery or to another voltage rail in a boosted system. The PVDD pin supplies the power to the output FETs and can be within the recommended operating limits, even if that is below the VBAT supply, to allow for dynamic voltage systems.

Several on-chip regulators are included for generating the voltages necessary for the internal circuitry. The external pins are provided only for bypass capacitors to filter the supply and should not be used to power other circuits.

The device can withstand fortuitous open ground and power conditions within the absolute maximum ratings for the device. Fortuitous open ground usually occurs when a speaker wire is shorted to ground, allowing for a second ground path through the body diode in the output FETs.
