4.1. HAL700
Magnetic Thresholds
(quasistationary: dB/dt<0.5 mT/ms)
at TJ = −40 °C to +140 °C, VDD = 3.8 V to 24 V,
The HAL700 consists of two independent latched
switches (see Fig. 4–1) with closely matched magnetic
characteristics controlling two independent open-drain
outputs. The Hall plates of the two switches are
spaced 2.35 mm apart.

In combination with an active target providing a
sequence of alternating magnetic north and south
poles, the sensor forms a system generating the sig-
nals required to control position, speed, and direction
of the target movement.
