Abstract

An electronic device and method for power management in an electronic device is provided. In an embodiment, the electronic device includes the functionality of a personal digital assistant, wireless email paging and a camera with a flash that is operated via self-contained power supply in the form of a battery. The device also includes a supervisor circuit which causes the device to enter sleep mode, or disables the device, or certain features of the device, if the battery level falls below a certain threshold. A method in accordance with an embodiment performs, in response to a request to fire the flash, a pre-flash test which is selected so as to not trip the supervisor circuit. The battery level is examined as a consequence of performing the pre-flash test and, if the battery level as so examined meets certain criteria, then the full flash is either permitted to proceed. If the battery level does not meet the criteria, the full flash is not permitted to proceed.

Description

technical field [0001] The present application relates generally to electronic devices, and more particularly to methods and apparatus for power management in electronic devices, such as multifunctional portable electronic devices including camera flashes and the like. Background technique [0002] Electronic devices are getting smaller and containing more functions. Combining the functionality of a conventional personal digital assistant (PDA) with the capabilities of wireless e-mail in a single device is well known, such as the Blackberry from RIM of Waterloo, Canada. TM is an example of such a device. It is also known to incorporate wireless voice functionality, music and video players into such devices. Gradually, cameras are being incorporated into such devices. [0003] With integration comes increased device complexity. Power management in such devices needs to reflect this complexity. For example, due to the portable nature of these devices, robust rechargeable ...
