Design a Custom BoardAbout This Component
Single-cell lithium-ion battery charger IC in SOT-23-6 package. Supports charging currents up to 1A with integrated charge control, constant-current/constant-voltage regulation, and over-temperature protection. Ideal for portable devices, power banks, and wearables requiring compact, integrated battery management.
Package: SOT-23-6 · 6 pins
Why does this need a breakout?
SOT-23-6 packages house precision regulators, voltage references, and level shifters with 0.95mm pin pitch—too fine for hand soldering and incompatible with breadboards. A breakout board provides through-hole headers for prototype work, eliminating soldering difficulty while enabling quick circuit iteration. Essential for developing with compact analog and power management ICs.
