? Description of Operations
Micropower Operation (Small current using intermittent action)
(Offset Cancelation)
(Magnetic Field Detection Mechanism)
The dual output 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約

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. 21 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.

The Hall IC cannot detect magnetic fields that run horizontal to the package top layer.
Be certain to configure the Hall IC so that the magnetic field is perpendicular to the top layer.
