GENERAL DESCRIPTION
The BC91801 isa complete constant-current/constant-voltage linear charger for single cell lithium battery. Its compact package with minimum external components requirement makes the BC91801 ideal for portable application. No external sense resistor or blocking diode is necessary for it. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature. The BC91801 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 enable once the batter’s charge curve
reaches the constant voltage portion. The output current then decays an is finally terminated once the charge current drops to 1/10 th of the programmed value. The
BC91801 keeps monitoring the battery voltage and enable a new charge cycle once the voltage drops by 250mV Below the CV value.
