Major Applications

Our new switch family HAL 15xy is the

optimal system solution for key applications

such as:

gear shift

for pumps and fans

System Architecture

HAL 15xy sensors are monolithic integrated

circuits which switch in response to mag-

netic fields. If a magnetic field with flux lines

perpendicular to the sensitive area is

applied to the sensor, the biased Hall plate

forces a Hall voltage proportional to this

field. The Hall voltage is compared with the

actual threshold level in the comparator. If

the magnetic field exceeds the threshold

levels, the output stage (open drain output

for 3-wire devices or current source for

2-wire devices) is switched to the appropri-

ate state.

The built-in hysteresis eliminates oscillation

and provides switching behavior of the out-

put without toggling. Magnetic offset caused

by mechanical stress is compensated by

using the “switching offset compensation

technique”.

The device is able to withstand a maximum

supply voltage of 24 V for unlimited time

and features overvoltage capability up to

40 V load dump.
