temperature characteristics is obtained, resulting in stable linear drive. If it is necessary to adjust the Hall output
amplitude, perform adjustment with R3.
FG Out (FG: Pin5) is an open drain output and R
The timing chart of FG Out is as follows.
Note that the pull up resistance shall be connected to below supply voltage.
The output voltage of hall elements is influenced by the bias current and magnetic flux density of hall elements.
The optimum input voltage of NJU7356 are 100mVp-p and higher. With such input voltage, the highest efficiency
