ETA6937
DESCRIPTION
The ETA6937 is a new generation of highly integrated synchronous switchmode charger, featuring integrated FETs and small external ponents, 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. The ETA6937 have three operation modes: charge mode, boost mode, and high impedance mode. In charge mode, the IC supports a precision Li-ion or Li-polymer charging system for single-cell applications. In boost mode, the IC boosts the battery voltage to VBUS for powering attached OTG devices. In high impedance mode, the IC stops charging or boosting and...
