1. General Description
ZCC5518 is a highly integrated synchronous
boost charger IC for Lithium-ion batteries
with four cells in series. The charge
current up to 1A 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.
