描述

ZCC6983 is a highly integrated synchronous boost

charger IC for Lithium-ion batteries with four cells in

series . The charge current up to 2A can be

programmed by using the external resistor for different

portable applications.

Robust protections include input over-voltage

protection (OVP), battery OVP, battery short protection,

thermal shut down, battery temperature monitor, a

configurable timer to prevent prolonged charging of a

dead battery.
