Abstract
A battery management chip which controls charging and discharging currents of a rechargeable battery. In a portable module, the battery manager chip controls the charging and discharging of the rechargeable battery which powers the whole module, and is therefore connected directly to the battery and to the source of charging current. The chip is also connected to draw very small amounts of current from a third, stable battery, preferably a lithium battery, which is not necessarily rechargeable.
