DIO5508B 600mA Lithium Ion Battery Charger IC Rev 1.1 Features  Programmable Charge Current Up to 600mA  Over Voltage Lockout Protection  Under Voltage Lockout Protection  Reverse current protection between BAT and GND pins  Automatic Recharge Threshold 4.05V (Typ.)  Charge Status Output Pin  2.9V Trickle Charge Threshold  Soft-Start Limits Inrush Current  Available in SOT23-6 package  Pb-free, rohs-compliant and Halogen-free Applications  Wireless phone  MP3/MP4 Player  Bluetooth device Descriptions The DIO5508B is a complete constant-current / constant voltage linear charger for single cell Lithium-Ion batteries. No external sense resistor is needed, and no blocking diode is required due to the internal MOSFET architecture. The charge voltage is fixed at 4.2V, and the charge current can be programmed externally with a single resistor. The DIO5508B automatically terminates the charge cycle when the charge current drops to 1/10 the programmed v...
