摘要： A flexible dual mode battery charger that charges a battery in two different modes, depending on the difference between the adapter voltage and the battery voltage, with a smooth transition between these two modes and the charging current remains relatively constant during the transition is provided in this application. At a lower battery level, the dual mode battery charger charges the battery as a LDO charger and when battery voltage is very close to the adapter voltage, the charger migrates its operating mode from the LDO mode to the boost mode and charges the battery as a boost charger. This flexible battery charger uses one common control circuit for controlling the operations of the LDO charger and the boost charger. The switching operation from one operation mode to other operation mode is smooth.

摘要： A method for diagnosing a control system for a stacked battery is disclosed. The control system comprises a plurality of processors, a plurality of controllers, and a monitoring unit (control unit). The method comprises sending a diagnostic information from the central unit to a top processor of the plurality of processors, transmitting a return information from the top processor of the plurality of processors to the central unit, comparing the diagnostic information sent from the central unit with the return information received by the central unit, and indicating a communication problem if the diagnostic information sent from the central unit is different from the return information received by the central unit. The steps are repeated by eliminating the top processor from a previous cycle and assigning a new top processor if there is no problem with the reconfigurable communication system.

摘要： Battery protection circuitry and method are disclosed. A battery is protected from a large current overdrawn condition by setting a discharge switch into a controllable conduction state. After the discharge switch is in the controllable conduction state, a tickle discharge current is gradually generated under control of a switch control signal. The trickle discharge current can be used to determine whether the large current overdrawn condition still exists. When the large current overdrawn condition is removed, the discharge switch is turned back on.
