EUP8051
Low Cost 1A Linear Battery Charge
DS8051 Ver 1.2 May. 2005
Controllers
DESCRIPTION
The EUP8051 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 EUP8051 applies a constant current up to 1A to the
battery and the charge current can be programmed
externally with a sense-resistor.
The EUP8051 automatically terminates the charge cycle
when the charge current drops to the charge termination
threshold (I
TERM
) after the charge-regulation voltage is
reached.
When the input supply is removed, the EUP8051
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.
