A3425
Ultra-Sensitive Dual-Channel Quadrature
Hall-Effect Bipolar Switch
Typical Applications Operation
V+
VOUTPUT(OFF)
VOUTPUT(ON)(sat)
B+
BHYS
Output voltage in relation to sensed magnetic flux density.
Output on each channel independently follows the same
pattern of transition through BOP followed by transition
through BRP.
Channel A
M agnetic Field
at Hall Element E1
Channel B
M agnetic Field
at Hall Element E2
Channel A
Output Signal
at OUTPUTA
Channel B
Output Signal
at OUTPUTB
Quadrature output signal configuration. The outputs of the two
output channels have a phase difference of 90º when used
with a properly designed magnet that has an optimal pole pitch
of twice the Hall element spacing of 1.0 mm.
