De nitions of Terms
The following provide additional information about some of
the parameters cited in the Operating Characteristics table.
For additional information, visit the Allegro Web site at
www.allegromicro.com.
Applied Magnetic Field, B
diff
The differential magnetic ux
density which is calculated as the arithmetic difference of the
ux densities observed by each of the two Hall elements.
Output Off Switchpoint (Operate Point), B
OP
The value of
increasing differential magnetic ux density at which the device
output switches from low to high. This value may be greater than
or less than 0 G.
Output On Switchpoint (Release Point), B
RP
The value of
decreasing differential magnetic ux density at which the device
output switches from high to low. This value may be greater
than or less than 0 G.
Power-On Time, t
PO
The time needed by the device, after
power is applied, to initialize all circuitry necessary for proper
operation.
Settling Time, t
Settle
The time required by the device, after t
PO
,
and after a valid magnetic signal has been applied, to provide
proper output transitions. Settling time is a function of magnetic
offset, offset polarity, signal phase, signal frequency, and signal
amplitude.
Response Time t
Response
The total time required for generat-
power-on time and settling time).
