DESCRIPTION
The SC71 is 3A Li-Ion battery charger. It utilizes a
500 KHz synchronous buck converter topology to
reduce power dissipation during charging. Low power
dissipation, an internal MOSFET allow a physically
small charger that can be embedded in a wide range of
handheld applications. The includes complete
charge termination circuitry, automatic recharge and a
±2% 8.4V float voltage. Battery charge current, charge
timeout and end-of-charge indication parameters are set
with external components. Additional features include
shorted cell detection; temperature qualified charging
and overvoltage protection. The is available in a
ESOP8 package
