GMT致新 G2246R41U TQFN3x3-16 22+2.5A集成开关模式单电池锂离子充电器

　　General Description

　　The G2246 is a integrated LI-ion switch-mode charger

　　and system power path management devices target at

　　space-limited portable applications. The input voltage

　　range with input overvoltage protection supports

　　unregulated power sources. The input dynamic power

　　management (VIN-DPM) prevents the charger from

　　crashing incorrectly configured power sources.

　　The built-in dynamic power path management (DPPM)

　　powers the system while simultaneously and

　　independently charging the battery. This feature

　　supply the system load at all time while monitoring the

　　charger current separately.

　　The charging current is determined by programming

　　ISET1 or ISET2 pin, and battery regulation voltage is

　　determined by VSET pin.
