描述
JZ5518 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.
