General Description
The LP4076B
is a highly advanced linear charger for
single-cell Li-Ion and Li-
Polymer batter
ideally suited for portable applications
of external
components required
The device employs a full
charge algorithm with trickle
current, constant current
(CC),
modes, charge termination
and
device supports charge current up to
by an
external resistor. The device can withstand an
input voltage up to 28V,
which can protect
from any
accidental insertion of
a hot insertion
. The device can withstand a BAT voltage
up to 14V,
which is suited for power battery application
Without an
input supply, the battery
only 30nA typical.
The device provides various safety features for battery
charging, including
input under voltage lockout (UVLO),
inputover-voltage protection
connection protection,
cold/hot battery temperature
protection,
and thermal regulation protection that is
implemented by reducing the charge current
junction temperature reaches 1
The LP4076B is available in a
