CN3767 Description

Short technical summary and product information.

The CN3767 from Consonance is a versatile PWM switch-mode battery charger controller specifically designed for 12V lead-acid battery applications. It supports trickle charge, constant current charge, over-charge, and float charge modes, with internally set regulation voltages for over-charge and float charge modes.

A key feature is its Photovoltaic Cell Maximum Power Point Tracking (MPPT) function, enabling efficient power management when used with solar panels. The device operates with a wide input voltage range from 6.6V to 30V and can deliver a charge current of up to 4A. Its high PWM switching frequency of 300KHz contributes to efficient operation.

The CN3767 is programmable for constant charge current using a single sense resistor. It includes automatic conditioning for deeply discharged batteries and automatic recharge functionality. The IC also features undervoltage lockout and status indication. It is available in a compact 10-pin SSOP package and operates within an ambient temperature range of -40℃ to +85℃.

Applications for the CN3767 include lead-acid battery chargers, UPS systems, portable industrial equipment, medical equipment, and standalone battery chargers.
