4056 Product details

Description

4056 4056 is a complete CC/CV linear charger for single cell lithium-ion batteries.it is specifically designed to work within USB power Specifications.No external sense resistor is needed and no blocking diode is required due to the internal P-MOSFET architecture.Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature .The charge voltage is fixed at 4.2V,and the charge current can be programmed externally with a

Features

include Battery temperature monitor, under-voltage lockout, automatic recharge and two status pins to indicate charge and charge termination. Features k Protection of battery cell reverse connection Programmable charge current up to 1.1A e No MOSFET sense resistor or blocking diode required Complete linear Charger for single Cell Lithium-Ion Batteries T CC and CV operation with thermal regulation to maximize Rate without risk of overheating Preset 4.2V charge voltage with ±1% accur.
