CONSONANCE 500mA USB-Compatible Lithium Ion Battery Charger CN3052A General Description: The CN3052A is a complete constant-current /constant voltage linear charger for single cell Li-ion and Li Polymer rechargeable batteries. The device contains an on-chip power MOSFET and eliminates the need for the external sense resistor and blocking diode. Furthermore, the CN3052A is specifically designed to work within USB power specifications. Its low external component count makes CN3052A ideally suited for portable applications. Thermal feedback regulates the charge current to limit the die temperature during high power operation or high ambient temperature. The regulation voltage is fixed at 4.2V with 1% accuracy.
