摘要: A method, apparatus, and non-transitory computer readable medium are provided for high current battery charging using IR dropout compensation. The method first measures a battery current value and then multiplies that battery current value by an effective resistance of the battery to produce an effective dropout voltage value. The effective battery voltage value is then compared with a desired battery top off voltage value. The switch mode battery charger output setpoint is adjusted based on the setpoint voltage. Battery current and terminal current are then compared. Charging is terminated if the battery current is less than the terminal current. If the battery current is greater than the terminal current the battery current value is measured again and the charging process continues until the condition is met.

摘要: An apparatus for discontinuously operating a receiver (302) includes a receive data circuitry (304) and processor circuitry (306). The apparatus and receiver (302) are incorporated in a communication device (104). The receiver (302) receives a communication signal (106) having a plurality of frames (200, 214, 224). Each of the frames has a synchronization field (202, 217, 222) followed by a data field (204, 218, 228). The receive data circuitry (304) synchronizes the communication device (104) with the communication signal (106) received by the receiver (302) according to an initial synchronization field (202). The receive data circuitry (304) decodes the following data field (204). The processor (306) evaluates the decoded data field. If the decoded data field indicates that the receiver (302) is locked, the processor (306) powers off the receiver (302) for the following synchronization fields (222).
