  • Low power enable circuit
    Patent number: 6144186
    Abstract: This invention is a system and method for causing a rechargeable battery pack to enter a low power mode. The system includes a resistive divider, a switch, a battery cell, and a safety integrated circuit. When an external voltage is applied to the resistive divider, the switch turns on. With the switch on, the safety integrated circuit senses only a fraction of the cell voltage and therefore puts the battery pack into a low power, or sleep mode. The battery is returned to normal mode by connecting a charger to the battery pack.
