KA2303

      The KA2303 is a monolithic intergrated circuit consisting of 3 functions (Forward,stop,Backword) designed for radio controlled toy car and other equipment.
      Here you can get some information about the features of KA2303 .First,it includes amplifier,detector,comparator,latch,voltage and actuator.The second is wide power supply voltage range (2.5 V to 10 V).Then is very low quiescent circuit current (Stop:I_CC=5 mA).Besides,it is capable of driving small DC motors in both direction.The last one is minimum number of external parts required.
      What comes next is about the absolute maximum ratings of KA2303  (Ta=25).The supply voltage (V_CC) is 11 V.The output current (continuous) (I_O(cont)) is 0.7 A.The output current (surge) (I_O(surge)) is 1.2 A.The power dissipation (P_d) is 500 mW.The operating temperature (T_OPR) is from -20 to +70.The storage temperature (T_TSO) is from -40 to +126.
      There are the electrical characteristics of KA2303  to follow (T_a=25,V_CC=5 V).The typical circiut current (I_CC1) is 40 mA and the maximum is 50 mA when without load.The typical circiut current (I_CC2) is 5 mA when stop.The typical input impendanxe (R_I) is 10k.The typical output saturation voltage (V_SAT) is 0.25 V and the maximum is 0.45 V at I_O=400 mA.The typical output sink current (I_SINK) is 10 mA.The typical sensitivity (V_I(sen)) is 3.5 mV at f=1KHz.The typical comparator hysteresis (HY) is 5 dB.
