CN3155 - 1A Lithium Titanate Battery Charger IC - CONSONANCE Hoja de datos

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.
