CONSONANCE 4A, 12V Lead-Acid Battery Charger IC CN3768 General Descriptions: The CN3768 is a PWM switch-mode battery charger controller for 12V lead-acid battery in a small package using few external ponents. The CN3768 is specially designed for charging 12V 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 internally set. The constant charge current is programmable with a single sense resistor. Deeply discharged batteries are automatically trickle charged at 17.5% of the programmed constant charge current until the cell voltage exceeds 75% of the regulation voltage in...
