1A Lithium Battery Charger
CN3066B
General Description:
The CN3066B 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.
Furthermore, the CN3066B is specifically designed
to work within USB power specifications. Its low
external component count makes CN3066B 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. When the input supply (wall adapter or USB
supply) is removed, the CN3066B automatically
enters a low power sleep mode, dropping the battery
drain current to less than 3uA. Other features include
under-voltage lockout, automatic recharge, battery
temperature sensing and charging/termination
indicator.
The CN3066B is available in a thermally enhanced
8-pin DFN package.
