ABSTRACT:
A battery management chip which controls charging and discharging currents of a rechargeable battery. Another significant teaching of the presently preferred embodiment is a battery manager integrated circuit which includes an on-chip bandgap voltage reference. The circuitry for bandgap voltage references is conventional, and a variety of circuit configurations are very well-known, but bandgap voltage references normally have a significant power consumption. However, the precise voltage reference derived from such a circuit is extremely useful in performing precise and optimal control of battery function.
