Pin Function
v Hall device power supply pins.
A voltage difference of 1.0 V is developed
between VH+ and VH–.

v Hall FG pin.
v The Hall waveform is converted into a
pulse signal and then used as the FG
pulse signal.
v When the Rf pin voltage becomes equal to
the CL pin voltage, the current limiter
operate. The CL voltage is determined
externally.
v Power supply for output block.
v This supply should be kept stable to
prevent ripple and noise from entering this
pin.
