螪escription of Operations
(Micropower Operation)
(Offset Cancelation)
The bipolar detection Hall IC adopts an intermittent operation method
to save energy. At startup, the Hall elements, amp, comparator and
other detection circuits 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: 48祍

Fig.65
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. 66 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.
