DESCRIPTION
The ASPM (Audio System Power Module) is an
integration of three high side drivers and five
regulators developed to provide the power for an
audio system.
The outputs of the IC are controlled via the I
bus and the Enable input.
External protection must be provided for reverse
battery protection.
