SGM41562
DESCRIPTION
The SGM41562 is highly integrated, I2C programmable, single-cell Li-Ion or Li-polymer battery charger with system power path management. It is specifically designed for portable applications requiring minimum board space and small external ponents. The charging profile includes pre-charge, constant-current and constant-voltage phases. Several safety and protection features are included such as built-in safe charge timer to set maximum duration of charge and pre-charge, input voltage and current monitoring, internal (junction) and external (battery) temperature monitoring, input current limiting and load current limiting. SGM41562 can charge with an input voltage range up to 6V charging range.
The SGM41562 has 3 power ports: input power port (IN), battery port (BAT) and system or load port (SYS). The system is powered from the input whenever it is available. Input is typically a USB power source. If the input source is weak or removed, power source for the system will...
