BL8576 1A Standalone Linear Li-Ion Battery Charge DESCRIPTION FEATURES The BL8576 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 BL8576 ideal for portable applications.  No external sense resistor or blocking diode is necessary for the BL8576. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The BL8576 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 1/10 of the programmed value. The BL8576 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 BL8576 senses a lack of input power. In its shutdown mode, the BL8576 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.
