EUP8051A Low Cost 1A Linear Battery Charge Controllers DESCRIPTION The EUP8051A is a single Lithium-Ion (Li-Ion) and Lithium–Polymer (Li-Pol) linear charge management controller for use in cost sensitive and portable applications. It combines high accuracy constant-current and constant-voltage regulation, cell preconditioning, temperature monitoring, automatic charge termination, charge-status indication, in a space-saving MSOP-8 package. The EUP8051A applies a constant current up to 1A to the battery and the charge current can be programmed externally with a sense-resistor. The EUP8051A automatically terminates the charge cycle when the charge current drops to the charge termination threshold (ITERM) after the charge-regulation voltage is reached.
