STBCFG01
STBCFG01: A switching battery charger integrating in the same chip the functions needed to
charge single cell Li-ion batteries, monitor the battery’s state of charge and generate 5 V to supply
USB OTG bus powered devices. The IC also integrates an LDO regulator to support system boot
in dead battery conditions. Battery charge indicators, or fuel gauges, have become essential for
managing devices such as smartphones, tablets and back-up battery packs. Accurate timeremaining predictions enhance the user’s experience, and can be critical in certain types of
portable electronics such as medical devices. The STBCFG01 uses accurate measurements of the
battery voltage to estimate the battery’s state-of-charge (SOC).

DC-DC Converters
S m a r t P o we r
ST’s DC-DC synchronous converters are designed for consumer and
portable applications.
Buck, buck-boost and boost switching regulators must provide low power
consumption, high-efficiency power conversion, and be available in very
small packages from standard leadless plastic to flip-chip pure bumped
silicon.
The switching frequency control loop guarantees high dynamic response
with very small inductor size.
All products are optimized to work with Li-ion batteries, USB sources or
the latest battery chemistries.
