As illustrated, is the use of integrated Hall element DN6839 dividing circuit. Circuit, the magnetic field detected by pulsating DN6839 whereby the pulse waveform, then the pul
se signal obtained by dividing the frequency of the desired pulse, this circuit are used for very high frequency pulsating magnetic field situations. Here with TC4013 is divided by 2, you can also use the A and B side pulse waveform output signal synthesizing other frequencies. DN6839 to switch type Hall element, in the form of open collector output is generally very easy with MOS integrated circuit interface. In addition, the open collector allows current is relatively large, can directly drive lO ~ 15mA load.
