Overview
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 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.
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 over-charge mode.
The over-charge is terminated once the charging current drops to 38% of the constant charge current, then CN3768 will enter float charge mode.
A new charge cycle automatically restarts if the battery voltage falls below 83.
95% of the over-charge voltage in float-charge mode.
CN3768 will a...
