The CN3302 is a PFM boost dual-cell lithium battery charging control IC manufactured by Consonance. It is designed to operate within an input voltage range of 2.75V to 6.5V. This IC utilizes a constant current (CC) and quasi-constant voltage mode (Quasi-CVTM) for efficient battery charging management.
Key features include integration of a reference voltage source, inductor current detection, battery voltage detection, and an external FET driver circuit, which contribute to a minimal component count and simplified circuit design. The device supports a maximum operating frequency of up to 1MHz. It also incorporates protection features such as over-temperature protection and chip enable input.
The CN3302 is suitable for dual-cell lithium battery charging applications. It employs a cycle of controlling external N-channel MOSFETs to manage inductor current rise and fall, transferring energy to the battery. The charging process transitions to a quasi-constant voltage mode when the battery voltage reaches approximately 8.4V.
This component is supplied in an 8-pin SOP8 package, designed for surface mount applications. Its design facilitates a simple circuit configuration for battery charging systems.
