CONSONANCE 1A Lithium Battery Charger IC CN3162 General Description: The CN3162 is a complete constant-current /constant voltage linear charger for single cell lithium rechargeable battery. The device contains an on-chip power MOSFET and eliminates the need for the external current sense resistor and blocking diode. Its low external component count makes CN3162 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 internally fixed at 4.2V, it can also be adjusted with an external resistor. The charge current can be programmed externally with a single resistor.
