General Descriptions:The CN3703 is  a PWM switch-mode  lithium ion  battery charger  controller for 3 cell  li-ion battery  in  a  small  package  using  few  external components. The CN3703 is    specially    designed    for charging  lithium  ion  batteries  with  constant current and constant voltage mode. In constant voltage  mode,  the regulation  voltage  is  fixed at  12.6V with ±1%  accuracy.The  constant charging   current   is   programmable   with   a single sense resistor. Deeply discharged batteries are automatically trickle charged at15% of the programmed constant charging current until the cell voltage exceeds 8.4V.The charge cycle is terminated once the charging current drops to a level set by an on-chip resistor and an external resistor, and a new charge cycle automatically restarts if the battery voltage falls below 12V. CN3703 will automatically enter sleep mode when input voltage is lower than battery voltage.Other  features  include  undervoltage  lockout, battery   temperature   monitoring   and status indication, etc.CN3703 is availablein  a  space-saving  16-pin TSSOP package.
