Descriptions
The DIO5508 is a plete 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 DIO5508 automatically terminates the charge cycle when the charge current drops to 1/10 the programmed value after the final...
