General Description

The ETA6937 is a new generation of highly integrated synchronous switchmode charger, featuring integrated FETs and small external components, targeted at extremely space-limited portable applications powered by 1-cell Li-Ion or Li-polymer battery pack.

Unlike previous generation of charging ICs (BQ2415X and FAN54015 etc.) that can barely deliver charge current up to 1.5A, thanks to ETA’s proprietary technology, ETA6937 packs a powerful punch and can delivery up to 3A of charge current, while still maintaining a small footprint of 2mmx1.6mm.

ETA6937 has bi-directional operation to achieve boost function for USB OTG support.
