    In the application shown, a conditioning phase slowly raises the voltage of a deeply discharged cell to a level suitable for fast-charging. After cell conditioning is complete, the microprocessor uses the GS64’S ADC converter to monitor the battery cell’s status and uses the power management block to control the charge-FET.
