General Descriptions:
The CN3768 is a PWM switch-mode battery charger controller for 12V lead-acid battery in a small package using few external components.
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.
