Application Information

It is strongly recommended that an external bypass ca-

pacitor can be connected (is close to the Hall sensor)

between the supply and the ground of the device to re-

duce both external noise and noise generated by the chop-

per-stabilization technique. This is especially true due to

the relatively high impedance of battery supplies.

Pole-independent

The pole-independent sensing technique allows for op-

eration with either a north or a south pole magnet

orientation, enhancing the manufacturability of the device.

The state-of-the-art technology provides the same output

polarity for either pole in presence.

Awake & Sleep

Internal awake & sleep timing block circuit activates the

sensor for 180 ms and deactivates it for the remainder of

the period (60 ms). A short “awake” time allows for stabi-

lization prior to the sensor sampling and data latching on

the falling edge of the timing pulse. While in sleep cycle,

the output is latched in its previous state.

Chopper Stabilized Technique

The chopper stabilized technique cancels the mismatch-

ing of the hall element, the amplifier offset voltage and

temperature sensitive drift by the dynamic offset cancel-

lation and switched capacitor technique. This technique

produces devices has an extremely stable Hall output

voltage, therefore, the magnetic switch points are stable.
