PRODUCT INFORMATION
HAL 15xy
First ISO 26262 Compliant Low-Power Hall Switch
The HAL 15xy family consists of different
Hall switches containing a temperature-
compensated Hall plate with active offset
compensation and comparator, available
optionally with open-drain or current output.
As global Hall switch supplier with long-term
experience since 1993, 1.5 billion shipped
automotive switches and leading expertise
in high-quality Hall-effect sensor solutions,
TDK-Micronas expands its switch portfolio
with the new HAL 15xy family.
All CMOS wafer processing is done in
TDK-Micronas’ facilities in Freiburg
(Germany) to ensure best quality control
and highest flexibility.
As improved successor of the well-known
HAL 5xy family, the HAL 15xy is available
as 3-wire version with short-circuit pro-
tected open-drain output and 2-wire version
with current output. HAL 15xy is available in
the smallest SOT23 as well as TO92UA
package and provides lowest power con-
sumption, fast response times, and special
safety features like a unique power-on self-
test for greater customer benefit at an
excellent price-performance ratio.
With different switching-point versions, the
HAL 15xy switch family serves a broad vari-
ety of automotive and industrial applications
under harsh temperature conditions.
HAL 15xy fulfills the latest quality and
functional safety standards as AEC-Q100
qualified and ISO 26262 ASIL ready device,
enabling our customers to target even the
most safety-critical applications.

Major Applications
Our new switch family HAL 15xy is the
optimal system solution for key applications
such as:
◆Position detection e.g. for seat belt and
gear shift
◆Index counting e.g. for window lift
◆Brushless DC motor commutation e.g.
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.
