General Descriptions:
The CN3765 is a PWM switch-mode multi-chemistry battery charger controller in a small package using few external components. The CN3765 is specially designed for charging lithium ion， LiFePO4 or Lithium Titanate batteries with constant current and constant voltage mode. In constant voltage mode, the regulation voltage is set by 2 external resistors. The constant charging current is programmable with a single current sense resistor.

FEATUREs:
● Wide Input Voltage: 6.6V to 30V
● Complete Charge Controller for Single or
   Multi-cell Lithium ion, LiFePO4 or
   Lithium Titanate Batteries
● Charge Current Up to 4A
● PWM Switching Frequency: 310KHz
● Can be used as Voltage Source when
   Battery is Absent
● Charging Current is programmed with a
   current sense resistor
● Automatic Conditioning of Deeply
   Discharged Batteries
● Automatic Recharge
● Charging Status Indication
● Soft Start
