8.4 Charger
This block can be used to charge a 4V Li-Ion accumulator. It supports constant current and constant voltage charging modes with adjustable
charging currents (94 to 1000mA) and maximum charging voltage (3.9 to 4.25V).
The charger consists basically of a pre-regulator, which limits the current from e.g. the USB input and provides a constant VSUP after reaching
EOC (end of charge) and the battery switch, which is controlling the current into the battery.
Input Voltage of the pre-regulator: VUSB
Output of the pre-regulator and input for the battery switch and system supply: VSUPSW
Output of the battery switch and battery terminal: VBATSW
CVM (constant voltage), CCM (constant current) and trickle charging
Adjustable EOC voltage and EOC current limit
Selectable input -, trickle- and charging-current limit
Auto-resume with selectable resume voltage level
Charger time-out supervision with selectable time-out setting
Battery temperature supervision supporting two levels (45 or 50oC) and 100k or 10k NTC types
No battery detection
Status register and interrupt generation
Per default the USB current limit is set to 470mA and the charger is switched off.
The current battery and charger input voltage can be measured with the general purpose ADC.
