The SC804 is a fully integrated full-feature, single cell constant-current/constant-voltag e (CC/CV) Lithium-Ion battery charger. With an integrated timer and complete charge control algorithm, the SC804 is ideal for standalone charger applications. The SC804 contains programmable pre-charge, fast-charge and termination current settings. The SC804 can be programmed to terminate charging based on the output current or the time-out of the programmable timer. The fast charge current is typically set with an external resistor, but it can also be adjusted by applying an analog voltage to the AFC pin. This feature allows use of a micro controller to set charging current via a DAC output.
The SC804's 14V input voltage range eliminates the need for additional protection circuitry required by other 5V chargers to protect against faulty adapters. The SC804 also incorporates an under-voltage lockout falling threshold of 3V so that charging will continue if the input supply goes into a current-limited mode.
Reference ground and battery sense inputs are provided to eliminate voltage drops during charging due to high charging currents.
The output voltage to the battery is controlled to within 1% of the programmed voltage. The SC804 can also function as a general purpose current source or as a current source for charging nickel-cadmium (NiCd) and nickelmetal- hydride (NiMH) batteries.
