ETA6937CSU可替代BQ24157/BQ24158

ETA6937CSU 12V/3A开关锂电池充电器和5V/1A OTG带I2C控制

12V/3A Switching Li+Battery Charger and 5V/1A OTG with I2C Control
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 cu...
