螪escription of Operations
(Micropower Operation)
(Offset Cancelation)
The unipolar detection Hall IC adopts an intermittent operation
method to save energy. At startup, the Hall elements, amp,
comparator and other detection circuit power ON and magnetic
detection begins. During standby, the detection circuits power
OFF, thereby reducing current consumption. The detection results
are held while standby is active, and then output.
Reference period: 50ms (MAX100ms)
Reference startup time: 24祍
Fig.39
The Hall elements form an equivalent Wheatstone (resistor)
bridge circuit. Offset voltage may be generated by a differential in
this bridge resistance, or can arise from changes in resistance
due to package or bonding stress. A dynamic offset cancellation
circuit is employed to cancel this offset voltage.
When Hall elements are connected as shown in Fig. 40 and a
magnetic field is applied perpendicular to the Hall elements,
voltage is generated at the mid-point terminal of the bridge. This
is known as Hall voltage.
Dynamic cancellation switches the wiring (shown in the figure) to
redirect the current flow to a 90?angle from its original path, and
thereby cancels the Hall voltage.
The magnetic signal (only) is maintained in the sample/hold
circuit during the offset cancellation process and then released.
