LP4056 IC – 1A Li-Ion Battery Charger IC

Overview Of This LP4056 IC – 1A Li-Ion Battery Charger IC

Introducing Roboway LP4056 IC – 1A Li-Ion Battery Charger IC at the best price in India with Roboway. It designed to safely charge single-cell Lithium-Ion (Li-Ion) or Lithium-Polymer (Li-Po) batteries from a USB port or a DC power source. This LP4056 IC uses Constant Current / Constant Voltage (CC/CV) charging technique, which is the standard for Li-Ion batteries, ensuring fast charging initially and safe topping-off at the end.

It can deliver up to 1A charging current, making it suitable for medium-sized batteries (e.g., 500mAh to 3000mAh). IC can be powered from USB (5V) or an adapter, so no complicated setup is needed. This LP4056 IC comes in a small package (often SOP-8), widely used in small electronics, DIY projects, and battery-powered devices.
