The bq25910 is an integrated three-level
switch-mode parallel battery charge management device for single cell Li-ion and Li-polymer
batteries. Utilization of the three-level converter maintains highest switch-mode operation
efficiency while reducing solution footprint and increasing power density. The device supports fast charging
with high input voltage for a wide range of portable devices. The solution integrates
reverse-blocking FET (QBLK), and four switching FETs
(QHSA, QHSB, QLSB,
QLSA). The I2C serial interface with charging and
system settings makes the device a truly flexible solution.
