Description

      The TC4804 is BICMOS optocoupled driver ICs for switching loads when electrical isolation is desired. Input drive current is converted to low impendance voltage drive with the ability to dirve 1.4 A peak current into a capacitive load of 1,000 pF with fast output rise and fall times. UV lockout circuitry forces the output to a "off" state when the input voltage drops below 7.8V. 0.4 V of hysteresis prevents output togging around the drop-out voltage. The output "off" state is low on TC4804 .
      TC4804 has seven unique features which is as follows: The first one is input to output isolation of 2.5KV RMS. The second one is operating range is from 10 V to 18 V . The third one is high peak output current which is 1.4 A typ. The forth one is short delay time which is less than 200 ns typ. The fifth one is fast switching on outputs. The sixth one is low power BICMOS design. The seventh one is undervoltage lock-out with hysteresis. Also, it has seven applications. The first one is isolated digital line driver. The second one is isolated line receiver. The third one is " High-Side" driver. The forth one is SMPS control. The fifth one is motor control. The sixth one is solld state relays.The seventh one is off-line regulation/control.
     What we should also pay more attention to is TC4804's specifications. First of all, let us know more about its absolute maximum ratings. Supply voltage is +20 V. Diode signal current input is 20 mA. Maximum chip temperature is 85. Storage temperature range is -55 to +125. Lead temperature(soldering , 10 sec) is +300. Power disspation is 300 mA. Next, we come to its electrical characteristics. LED forward threshold current(DC)(IFTH) is 3.0 mA typ and 10 mA max.LED forward maximum current(continuous)(IFMAX) is 20 mA. LED forward voltage (at 10 mA current)(VF) is 1.3 V min , 1.5 V typ and 1.7 V max. LED reverse voltage(at 50 nA) is 6.0 V min. Isolation voltage is 2.5 kVRms min. Start up threshold(Vs) is 8.7 V typ and 10.0 V max. Drop-out threshold(Vuv) is 7.5 V min and 8.4 V typ.
    In a word, it is a general introduction of this kind of product and if you are interested in it and want to know more about it , please pay more attention to our web for that you will get more information about TC4804 . Thanks for your attention to our web and our information!
