Overview
CONSONANCE 500mA LiFePO4 Battery Charger CN3058 General 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 cha...
