BL8572
GENERAL DESCRIPTION
The BL8572 is a single cell, fully integrated
constant current (CC)/constant voltage (CV) Li-ion
battery charger. Its compact package with
minimum external components requirement makes
the BL8572 ideal for portable applications.
No external sense resistor or blocking diode is
necessary for the BL8572. Build-in thermal
feedback mechanism regulates the charge current
to control the die temperature during high power
operation or at elevated ambient temperature.
The BL8572 has a pre-charge function for trickle
charging deeply discharged batteries. The fast
charge current can be programmed by an external
resistor. CV regulation mode is automatically
enabled once the battery’s charging curve reaches
the constant voltage portion. The output current
then decays and is finally terminated once the
charge current drops to 1/10th of the programmed
value. The BL8572 keeps monitoring the battery
voltage and enables a new charge cycle once the
voltage drops by 150mV below the CV value.
Power supply state is constantly monitored and the
battery drain current is reduced to minimum value
automatically when the BL8572 senses a lack of
input power. In its shutdown mode, the BL8572
can reduce the supply current to less than 25µA. A
status pin outputs a logic HIGH/LOW to indicate
the charging status and the presence of power
supply.
Other features include charge current monitor,
under-voltage lockout.
