DIO5508B - 600mA Lithium Ion Battery Charger IC

General Description

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.

Key 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.
