Abstract: | A lithium-ion (Li-ion) battery protection IC with an average current of 0.99 muA (at a battery voltage of 3.6 V) and a standby current (after detecting over-discharge) less than 0.01 muA is presented. This low power performance is achieved via a power-on duty-cycle technique. The protection circuit samples the voltage of the battery periodically and powers down during the rest of time. This Li-ion battery protector provides overcharge, over-discharge, excess-current and short circuits protection. This protection IC was implemented in a 0.6-mum CMOS technology and the active area is 880 mum x 780 mum. |
