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.
