2.5A 2-Cell Li⁺Battery Charger with 2.4A Buck OTG function

DESCRIPTION

FEATURES

ETA6071 is a wide input range, high efficiency, 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-Ion batteries. The charging current

and termination voltage can both be programmed through

external resistors. There are also an input current limit setting

and a dynamic input power management setting. These

features can be used for limiting the charging current when a

weak power source is plugged in. The boost has a true-shutoff

function that disconnects the input from output when short

circuit or shut down occurs. A NTC function is also included to

configure charging at different 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

batteries to VBUS. It can deliver up to 2A at 5V.
