SDC3731 ic

UNIVERSAL CHARGER

     APPLICATIONS

  Support the general pattern of three lights and two lights models
Automatic battery polarity identification
Charge saturation voltage 4.25V (typical value), can be               adjusted through the L1  
No-load output voltage regulator
Short-circuit protection
Minimal external device           

     FEATURES

    And internal integration: resistor (1/4W, 1/8W), transistor (8550), dual operational amplifier (358), switching devices,  etc.It minimizes the external components of the charger.

The SDC3731 is a universal charger ,can automatically identify IC with a battery "polarity  identification" system and control cells effectively.It can keep the charger circuit work in the normal stage no matter how the cell polarity  access the circuit.
