Abstract
A battery protection chip, a polling detection method and a polling detection circuit based on a battery protection chip are provided. The circuit includes: a polling signal generator generating first and second selection signals based on a basic clock signal, a plurality of state signals and a priority of a plurality of detection items. An input array selector selects one of a plurality of reference signals and one of a plurality of feedback signals to output to a comparator based on the first selection signal; the comparator compares the feedback reference signals and outputs an indication signal. An output sampler samples the indication signal according to the second selection signal and updates the plurality of state signals according to a sampling result.
