The SMB2353 is a fully programmable, integrated battery charger and system power manager for designs using dual-cell Li-ion and Li-polymer battery packs. The high-efficiency, switch-mode operation of the SMB2353 reduces heat dissipation and allows higher current capability (up to 6 A) for a given package size to the battery, to the system, or to both the sys...
The SMB2353 is a fully programmable, integrated battery charger and system power manager for designs using dual-cell Li-ion and Li-polymer battery packs. The high-efficiency, switch-mode operation of the SMB2353 reduces heat dissipation and allows higher current capability (up to 6 A) for a given package size to the battery, to the system, or to both the system and the battery. The SMB2353 can operate in the buck, buck-boost, or boost mode, there by allowing charging and power delivery from a wide variety of power sources. It can tole...
