Design a Custom BoardAbout This Component
Single-cell Li-ion battery charger IC with integrated MOSFET and power management for 1S battery systems. Supports up to 3A charging current with input voltage range of 4.5V to 24V, featuring dynamic power path management and thermal regulation. Typical applications include portable power banks, small drones, and single-cell lithium battery systems requiring compact, integrated charging solutions.
Package: WQFN-24-1EP (4×4mm, EP) · 24 pins
Why does this need a breakout?
This 0.5mm pitch QFN-24 package requires a breakout board to prototype effectively — hand soldering the fine-pitch pads is impractical, and the bottom-side exposed pad cannot be accessed on breadboards. A breakout routes the 24 pins to standard headers, enabling rapid testing of multi-channel DACs, ADCs, VCOs, and other analog signal processors without reflow equipment.
