ABSTRACT:
A system and method for implementing a multi-voltage multi-battery power management integrated circuit. Various aspects of the present invention provide a power management integrated circuit. The power management IC may comprise a first regulator module that receives a first battery power signal from a first battery characterized by a first battery voltage and outputs a first regulated power signal, based at least in part on the first battery power signal. The power management IC may also comprise a second regulator module that receives a second battery power signal from a second battery characterized by a second battery voltage and outputs a second regulated power signal, based at least in part on the second battery power signal. The second battery voltage may, for example, be substantially different than the first battery voltage. The power first and second regulated power signals may, for example, correspond to substantially different power supply voltages.
