CN3717 Datasheet | CONSONANCE

CONSONANCE 5A, Lead-Acid Battery Charger IC General Descriptions: The CN3717 is a PWM switch-mode battery charger controller for lead-acid battery in a small package using few external ponents. The CN3717 is specially designed for charging lead-acid battery with trickle charge, constant current charge, over-charge and float charge mode. In over-charge and float charge mode, the regulation voltage is set by the external resistor divider. The constant charging current is programmable with a single sense resistor. Deeply discharged batteries are automatically trickle charged at 19% of the programmed constant charging current until the cell voltage exceeds 75.6% of the regulation...
