General Description
The SC8088 is a 3A Li-Ion battery charger. It utilizes a 500KHz 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 SC8088 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V /8.4V /12.6V /16.8V 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 SC8088 is available in a low profile ESOP10 package.
Features
Input voltage range 4V~22V
Dynamic input current allocation for maximum charging rate
3.0A Maximum Charge Current
No External MOSFETs and Blocking Diode Required
Efficiency up to 90%
