钰泰 ETA4056D2I DFN-8 电池充电管理芯片
DESCRIPTION
ETA4056isa single cll, flly itegrated constant urent (C)/constant voltage (CV)
Li-ion bttery charger. Its compact package with minimum external components
requirement makes the ETA4056 ideal for portable aplicationso. No extemal sense
resistor or blocking dioce is necessary for the ETA4056. Buildin thermal fedbac
mechanism rgulates the charge urent to control the die temperature during high
power operation or at elevated ambient temperature. The ETA4056 has a pre- charge
function for tikle charging deeply discharged bttries. The fast charge crrentan
be programmed by an extemal resistor. CV regulation mode is automaically
enabled once the batryschargingcurve reaches the constant voltage portin. The
output crrent then decays and is fnally terminated once the charge current drops
to 1/10th of the programmed value. The ETA4056 keeps monitoring the battery
voltage and enables a new charge cycle once the voltage drops by 120mV below
the CV value.
ETA4056is in an ESOP8, DFN2x2 8, DFN2x3- 8, and SOT23-6 package.
