ME4054B-N Overview
ME4054B-N is a plete constant-current/ constant voltage linear charger for single cell lithium-ion batteries. Furthermore the ME4054B-N is specifically designed to work within USB power specifications. No external sense resistor is needed and no blocking diode is required due to the internal PMOSFET architecture .Thermal feedback regulates the charge current to limit the die temperature during high power operation...
