CONSONANCE 1A Lithium Battery Charger IC CN3152 General Description: The CN3152 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.
Its low external component count makes CN3152 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.
The charge current can be set externally with a single resistor.
When the input supply is remov...
