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 I2C bus and the Enable input.
External protection must be provided for reverse battery protection.
■ 5 REGULATORS10V (350mA); 8.5V (175mA);5V (350mA); 5V (250mA); 8V/10V (1A)
■ ALL REGULATORS ARE LOW DROPOUT OUPUTS
■ 3 HIGH SIDE DRIVERS:2A (HSD1), 0.45A (HSD2 & HSD3)
■ NO EXTERNAL CHARGE PUMP CAPACITORS ARE REQUIRED
