ChipSourceTek CST4056E
CST4056E 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. The CST4056E automatically terminates the charge cycle when the charge current drops to 1/10th the programmed value after the final float voltage is reached.When the input supply (wall adapter or USB supply) is removed the CST4056E automatically enters a low current state dropping the battery drain current to less than 1μA.| Part No. | CST4056E |
