Hall IC element DN6839 dividing circuit diagram

The circuit utilizes the integrated Hall element DN6839 for frequency division. It detects a magnetic field through the pulsating DN6839, generating a pulse waveform. The circuit is designed for applications involving very high-frequency pulsating magnetic fields. It employs the TC4013 to divide the frequency by 2, and the A and B side pulse waveform outputs can be synthesized to create other frequencies. The DN6839 functions as a switch-type Hall element with an open collector output, facilitating easy interfacing with MOS integrated circuits. Additionally, the open collector can handle a relatively large current, capable of directly driving loads of 10 to 15 mA.

The circuit design leverages the properties of the DN6839 Hall effect sensor, which is capable of detecting magnetic fields and converting them into electrical signals. The output from the DN6839 is a digital pulse that corresponds to the presence or absence of a magnetic field, making it suitable for applications such as position sensing or speed detection in motor control systems.

The TC4013, a dual D-type flip-flop, is utilized to divide the frequency of the output signal from the DN6839. By configuring the TC4013 in a toggle mode, the output frequency can be effectively halved, allowing for precise control over the timing of the output pulses. This feature is particularly beneficial in applications requiring specific timing sequences or pulse modulation.

The open collector output of the DN6839 provides versatility in interfacing with various digital circuits, including microcontrollers and other logic devices. This output configuration allows for multiple sensors to be connected to a single line without signal interference, enabling a more compact and efficient design. The capability to drive loads of 10 to 15 mA ensures that the circuit can directly control indicators, relays, or other devices without the need for additional driver stages.
