描述

ZCC6982 is a highly integrated synchronous boostcharger IC for Lithium-ion batteries with four cells inseries . The charge current up to 2A can beprogrammed by using the external resistor for differentportable applications.Robust protections include input over-voltageprotection (OVP), battery OVP, battery short protection,thermal shut down, battery temperature monitor, aconfigurable timer to prevent prolonged charging of adead battery.
