BL4056 Description
BL4056 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 BL4056 ideally suited for portable applications. Furthermore the BL4056 is specifically designed to work within USB power specifications.
