The SC905 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 LDOs enable and output
voltage are controlled via the I2C bus.
An optional three-wire interface compatible with Semtech battery charger ICs is also controlled via the I2C bus.
Initial power-on is achieved by activating either the ON ...
