ME4057 Description
ME4057 is a plete constant-current/constant voltage linear charger for single cell lithium-ion batteries. With a thermally enhanced 8-PIN SOP package on the bottom and low external ponent count make the ME4057 ideally suited for portable applications. Furthermore the ME4057 is specifically designed to work within USB power specifications.
