DESCRIPTION
An external resistor sets the magnitude of the charge current. Charge is terminated based on minimum current. An internal charge timer provides a backup safety for charge termination. The device automatically restarts the charge if the battery voltage falls below an internal threshold. The device automatically enters sleep mode when the ac adapter is removed.
