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
2 z9 E, d: r5 dprotection (OVP), battery OVP, battery short protection,
thermal shut down, battery temperature monitor, a
5 e4 N0 C( f; X8 Y& @; \3 C: Vconfigurable timer to prevent prolonged charging of a
dead battery.
