摘要： A method, an apparatus, and a computer program product for booting the apparatus with a low-energy battery are provided. In a first configuration, the apparatus monitors a level of the battery while the battery is charging. The apparatus attempts a boot of the apparatus when the level is greater than or equal to a dynamic boot threshold. The apparatus increases the dynamic boot threshold when the boot is unsuccessful and repeating the monitoring and the attempting based on the increased dynamic boot threshold. In a second configuration, the apparatus detects a connection to an external power source. The apparatus attempts a boot using an FLCB protocol that is based upon power drawn directly from the external power source upon detecting the connection to the external power source. The apparatus attempts the boot as part of an ATC protocol when the boot using the FLCB protocol is unsuccessful.

摘要： A method and apparatus for current drain switching with a replica loop. The method comprises the steps of: matching a voltage across a current sense resistor with a voltage created by a reference current across a matched reference resistor; replicating an operating point of an output transistor using a scaled matched replica of the output transistor and the current sense resistor. The method then shifts a feedback voltage from the output sense resistor to the matched replica sensor and shifts the output of a gate from an output transistor to the replica transistor. A first switch is then actuated in order to preserve the gate charge of the output transistor. A second switch is actuated to sample and hold a drain voltage in the buffer in order to bias the drain of the replica transistor. The third switch is then activated to stop the output current.
