Overview
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.
When the input supply is removed, the EUP8051A automatically enters a low-power sleep mode, dropping the battery drain current to less than 1µA.
A battery charge state output pin is provided to indicate battery charge status through a display LED.
The battery charge status output is a serial interface which may also be read by a system microcontroller.
