Eutech Microelectronics EUP8057
The EUP8057 is a highly advanced 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, 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.| Part No. | EUP8057 |

DESCRIPTION
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.FEATURES
