  • Patent number: 10491023
    Abstract: A driver circuit includes two high-side switches and a single low-side switch, output inductor, and output capacitor. By having multiple high-side switches, the driver can regulate power from multiple charging devices. The high-side switches share a channel with an input capacitor for that channel and the channels are connected to the low-side switch at a common node. When the capacitor for one of the channels becomes charged quickly, the capacitor of the other channel will balance itself with the charged capacitor. To avoid damaging the high-side switches, a low-impedance bridge and driver circuit is connected between the channels.

  • Patent number: 9146282
    Abstract: Systems and methods are disclosed for detecting whether a battery in an electronic device is counterfeit or defective. An actual battery characteristic profile is generated by recording the performance of the battery during use of the battery by the device. This profile is then compared to its corresponding expected characteristic profile. If the profiles are not substantially similar (i.e. if the error between the two curves exceeds a given error threshold), the battery is determined to be counterfeit or defective and responsive action is taken.
