描述
ZCC6982 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.
