Claim 9:
10. A system, comprising:
a first battery cell;
a second battery cell coupled to the first battery cell; and
an integrated circuit (IC) coupled to the first and second battery cells, the IC comprising:
a multiplexer (MUX) having a pair of MUX outputs, multiple MUX battery cell inputs, and a MUX control input, the multiple MUX battery cell inputs coupled to each of the first and second battery cells;
a comparator having a comparator output, a pair of comparator battery cell inputs, and a comparator threshold input, the pair of comparator battery cell inputs coupled to the pair of MUX outputs, the comparator threshold input adapted to be coupled to a threshold voltage source; and
a digital control circuit comprising:
a set of registers, each register in the set of registers having a register output, a register input, and a register clock input, the register clock inputs adapted to be coupled to a clock source;
a register controller having a set of register controller outputs, a register controller input, and a register controller clock input, each register controller output in the set of register controller outputs coupled to a different data register input, the register controller input coupled to the comparator output, the register controller clock input adapted to be coupled to the clock source;
a MUX controller having a MUX controller output and MUX controller clock input, the MUX controller output coupled to the MUX control input, the MUX controller clock input adapted to be coupled to the clock source; and
a logic AND gate having an AND gate output and a set of AND gate inputs, each AND gate input in the set of AND gate inputs coupled to a different register output.
