CONSONANCE 1A Lithium Titanate Battery Charger IC CN3155 General Description: The CN3155 is a complete constant-current /constant voltage linear charger for single cell or dual-cell lithium titanate rechargeable batteries. 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 CN3155 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 2.75V or 5.5V depending on CELL pin voltage level, it can also be adjusted upwards with an external resistor. The charge current can be programmed externally with a single resistor.
