Description

The EUP8057 is a highly advanced Lithium-Ion (Li-Ion) and LithiumPolymer (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, TSSOP-8 package.

The EUP8057 applies a constant current up to 1A to the battery and the charge current can be programmed externally with a sense-resistor.

The EUP8057 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 EUP8057 automatically enters a low-power sleep mode.

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.
