IC BATT CHG LI-ION 1CELL 16QFN


Bypass caps, pull-ups, strapping resistors, custom silkscreen & more
Design a Custom BoardSingle-cell Li-Ion battery charger IC in 16-pin QFN package. Integrates power transistor and control circuitry for autonomous charging with programmable charge current via external resistor. Typical applications include portable electronics, power banks, and IoT devices requiring compact battery management solutions.
This 3×3mm QFN-16 with 0.5mm pitch requires a breakout board to prototype effectively. The fine pitch makes hand soldering nearly impossible, and the hidden pads underneath prevent breadboard use entirely. A breakout board converts the package to through-hole or larger pads, enabling rapid iteration with wideband amplifiers, motor drivers, and power management ICs that typically use this footprint.
