Description
The STEVAL-ISB006V1 demonstration board is
based on the STw4102, a stand-alone constant-
current constant-voltage (CCCV) linear charger
dedicated for Li-Ion battery. This device allows
dual charging capability using the main input
adaptor up to 1A (wall adaptor, car adaptor) or
USB cable up to 500 mA without external
component. Upper 1 A charging is possible by
adding just one external transistor. This
demonstration board offers programmable fast
charge current up to 1A with external resistor. A
thermal regulation circuitry limits the charge

current against the die high power dissipation or
high ambient temperature. An end of charge
output pin indicates the charge termination when
the fast charge current drops below 10% of the
programmed current value. The STw4102
contains an accurate gas gauge based on a 13 bit
AD converter. External resistor is used between
battery and ground to sense a charge/discharge
current. With a typical 30 mΩ resistor, current can
be up to 2.5 A.
