Method and apparatus for managing power-up of a portable communication device

A battery operated portable communication device (100) provides improved power up of converged functionality managed by a power arbitration module (PAM) (104), a baseband processor (BP) (108), and an applications processor (AP) (104). In response to a control switch (120) being turned on, the baseba...

More Information
Summary:A battery operated portable communication device (100) provides improved power up of converged functionality managed by a power arbitration module (PAM) (104), a baseband processor (BP) (108), and an applications processor (AP) (104). In response to a control switch (120) being turned on, the baseband processor generates a time delay and asserts a boot-line to the applications processor which prevents full power up of the applications processor and during which a battery impedance is read, thereby preventing simultaneous power up of the AP and BP. The boot-line from the baseband processor to the applications processor is released once the BP power up is complete and battery impedance is read.
