BL8578
DESCRIPTION
The BL8578 is a 1.6A Li-Ion battery switching charger intended for 5V adapters. Low power dissipation, an internal MOSFET and its compact package with minimum external components requirement makes the BL8578 ideal for portable applications. The BL8578 includes complete charge termination circuitry, automatic recharge and a ±1% 4.2V/4.35V float voltage.
External sense resistor and Reverse diode is not need. Build-in thermal feedback mechanism regulates the charge current to control the die temperature during high power operation or at elevated ambient temperature.
Battery charge current, charge timeout and endof-charge indication parameters can program by external components. Additional features include shorted cell detection and overvoltage protection.
The BL8578 is available in DFN3x3-10L package.
