The quick charge mode conversion circuit of the rechargeable battery (charge charge mode)

摘要

The present invention relates to a rapid charge mode conversion circuit for a chargeable battery that compensates for the influence of a leakage current by using a chargeable battery voltage difference detection method. A voltage difference compensating unit for compensating for a voltage difference that is increased by a leakage current by using a voltage output from the voltage difference amplifying unit as an input; A comparator for comparing a voltage output from the voltage difference amplifier with a voltage output from the voltage compensator and a voltage output from the voltage difference amplifier and the voltage compensator to sense a normal operation of the voltage compensator, Normal operation detection and initial pulse elimination for eliminating and outputting the initial pulse before the buffer generated in the output voltage And, it is configured to include the comparison unit and the parts of the normal operation sense, and by the signal outputted from the initial pulse removing the input logic to the output of the final output voltage only when the voltage compensation addition normal operation.
