钰泰 ETA6071 QFN-20 电池充电管理芯片

DESCRIPTION
ETA6071 is a wide input range, high eciency, synchronous 2-cell series Li-Ion
battery cell boost charger. It accepts input from 2.7V to 7V and is capable of
delivering up to 2.5A charge current to two stacked Li-lon batteries. The
charging current and termination voltage can both be programmed through
external resistors. There are also an input current limit stting and a dynamic
input power management sttng. These features can be used for limiting the
charging crrent whena weak power soure isplugged in. The boost has atrue-
shutof function that disconnects the input from output when short circuit or
shut down ocCurS. A NTC function is also incduded to configure charging at
difrent temperatures. A STAT function indicates charging status. Furthermore,
ETA6071 incorporates an OTG function that when enabled, with the same
inductor, one can reversely deliver power from the barteries to VBUS. It can

deliver up to 2A at 5V.
