DESCRIPTION
The A4061 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 A4061 ideal for portable applications.
No external sense resistor or blocking diode is necessary for the A4061. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature.
The A4061 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 A4061 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 A4061 senses a lack of input power. In its shutdown mode, the A4061 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.
The A4061 is available in SOT-26 and PSOP8 packages.
