ACE Technology ACE4722
The ACE4722(Note 1) is a PWM switch-mode battery charger controller that can be powered by photovoltaic cell with maximum power point tracking function. The ACE4722 is specially designed for charging 1 or multi-cell lithium ion batteries or LiFePO4 batteries with constant current and constant voltage mode. The constant charging current is programmable with a single current sense resistor.| Part No. | ACE4722 |

DESCRIPTION
In constant voltage mode, the regulation voltage is set by the external resistor divider. Deeply discharged batteries are automatically trickle charged at 15% of the programmed constant charging current until the cell voltage exceeds 66.7% of the regulation voltage. In constant voltage mode, the charging current decreases gradually, the charge cycle will be terminated when the charging current drops to 9.5% of the full-scale current, and a new charge cycle automatically restarts if the battery voltage falls below 95.8% of the regulation voltage in constant voltage mode. ACE4722 will automatically enter sleep mode when input voltage is lower than battery voltage. Other features include undervoltage lockout, battery temperature monitoring and status indication, etc.FEATURES
