Description
The CN3058 is a complete constant-current /constant
voltage linear charger for single cell LiFePO4
rechargeable batteries. The device contains an
on-chip power MOSFET and eliminates the need for
the external sense resistor and blocking diode. Its
low external component count makes CN3058
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 3.6V with
1.5 accuracy, 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 CN3058 automatically enters a low
power sleep mode , dropping the battery drain
current to less than 3uA. Other features include
undervoltage lockout, automatic recharge, battery
temperature sensing and charging/termination
indicator.
The CN3058 is available in 8-pin SOP package.
