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 REGULATORS 10V (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

■ STAND BY MODE CONTROLLED BY 3 INPUT PINS: ENABLE FOR REG2 AND REG3, I2C BUS FOR REG1, REG4, REG5, HSD1, HSD2, HSD3

■ INDIVIDUAL THERMAL SHUTDOWN

■ INDEPENDENT CURRENT LIMITING

■ SHORT CIRCUIT PROTECTION

■ LOAD DUMP PROTECTION AND OVERVOLTAGE SHUTDOWN

■ ESD PROTECTED
