钰泰 ETA4056E8A ESOP-8 电池充电管理芯片
科瑞芯供应-ETA4056E8A-1.2A/16V全集成线性充电器1 Cell锂离子电池
DESCRIPTION
ETA4056is a single cll,l 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 diode is necessary for the ETA4056. Build-in thermal fedback
mechanism regulates the charge curent t0 contol the die temperature duing high
power operation or at elevated ambient temperature. The ETA4056 has a pre- charge
function for tickle charging deeply discharged bttres. The fast charge curentcan
be programmed by an external resistor. CV regulation mode is automatically
enabled once the batryscharingcurve reaches the constant voltage portin. The
output crrent then decays and is fnallyl terminated once the charge crrent drps
to 1/10th of the programmed value. The ETA4056 keeps monitoring the battery
voltage and enables a new charge cydle once the voltage drops by 120mV below
the CV value.
ETA4056is in an ESOP8, DFN2x2 8, DFNx3-8, and SOT23-6package.
