GENERAL DESCRIPTION
In trickle charge mode, a safe Lithium-ion and Lithium polymer battery charge is possible because approximately only 1/10 of the full charge current is supplied to the battery. As it is possible to select a highly accurate charge current of either 100mA (MAX.) for L level input to the LIM pin or 500mA (MAX.) for H level, the series is ideal for applications where the charge is from USB. The series’ charge status output pin, /CHG pin, is capable of checking the IC’s charging state via connection to an external LED.●
APPLICATIONS
● USB charge applications● Charging docks, charging cradles
● MP3 players, portable audio players
● Cellular phones, PDAs
● Bluetooth headsets
