Charger
9.4.1
General
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 (55 to 460mA) and maximum charging voltage (3.9 to 4.25V).
An internal protection circuit will limit the charging current when a CHGIN voltage drop is detected.
For the end of charge current four levels can be selected while the battery temperature shutdown has two temperature
levels to choose from.
The current battery voltage as well as the actual charging current can be measured with the general purpose ADC.
