SC8921
DESCRIPTION
2 FEATURES
The SC8921 is a highly integrated switch-mode boost charger
- Integrated Synchronous Boost Charger for two cell Li-ion battery applications. It is able to step up
- 4.5V~5.5V input voltage to up to 16V, and provide battery charge management functions including trickle charge, constant current charge, constant voltage charge, charge
Charging Management (Trickle Charge / Constant Current Charge / Constant Voltage Charge / Charge Termination) termination and charging status indication.
- Programmable Constant Charge Current
The SC8921 supports flexible charge current option, and the
- user can program the current freely through external resistor
- for different applications. With the charger management function, the IC can be used to charge 2 cell Li-ion battery.
- 技
- k The SC8921 supports 2A input current limit, input under voltage and over voltage protections, internal cycle by cycle
- current limit, battery short circuit protection, and output over...
