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 G2246 is 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.
