POWER MANAGEMENT Description
The SC905A is a power management integrated circuit (PMIC) designed for the latest CDMA chip sets.
The device provides four general purpose low dropout
regulators (LDOs), and five low noise LDOs designed for analog circuits.
The VMOT LDO can be used as a general purpose
regulator or as an adjustable motor drive output that can supply up to 150mA to drive a vibrator motor.
Each LDO’s enable and output voltage are controlled via the I2C bus.
The VTCXO output has an external enable pin that can be used instead of the register bit when timing is critical for minimizing sleep current.
The VMOT also has an ext...
