Method and Apparatus for Handling a Charging State in a Mobile Electronic Device
First Claim
1. A mobile device comprising:
- a voltage supervisor and reset (VSAR) module configured to detect an input voltage, start a timer set to a predetermined time period responsive to detecting the input voltage, and output a low signal responsive to detecting the input voltage;
a battery charger module configured to receive the input voltage, receive the low signal, output a power signal, and charge a battery;
a processing module configured to receive the power signal, and attempt enumeration responsive to receiving the power signal,the VSAR module further configured to output a high signal to the battery charger module when the timer expires and enumeration has not been completed.

Abstract
Disclosed is a mobile device comprising a voltage supervisor and reset (VSAR) module configured to detect an input voltage, start a timer set to a predetermined time period responsive to detecting the input voltage, and output a low signal responsive to detecting the input voltage. The mobile device also comprises a battery charger module configured to receive the input voltage, receive the low signal, output a power signal, and charge a battery. The mobile device also comprises a processing module configured to receive the power signal, and attempt enumeration responsive to receiving the power signal, wherein the VSAR module is further configured to output a high signal to the battery charger module when the timer expires and enumeration has not been completed.
