April/2016
HAL® 15xy
First ISO 26262 Compliant Low-Power Hall Switch
The HAL 15xy family consists of different
Hall switches containing a temperaturecompensated 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,
Micronas expands its large switch portfolio
with the new HAL 15xy family.
All CMOS wafer processing is done in
Micronas’ facilities in Freiburg (Germany) to
ensure best quality control and highest flexibility.
With different switching-point versions, the
HAL 15xy switch family serves a broad variety 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.
Features
◆ Sampling and output refresh time of 2 s
◆ 3-wire version with a short-circuit protected open-drain output
◆ 2-wire version with current output
As improved successor of the well-known
HAL 5xy family, the HAL 15xy is available
as 3-wire version with short-circuit protected 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 consumption, fast response times, and special
safety features like a unique power-on selftest for greater customer benefit at an
excellent price-performance ratio.

◆ Wide supply voltage operation from
2.7 V to 24 V
◆ Overvoltage protection capability
up to 40 V
◆ Available in the small SOT23 and
TO92UA package
◆ High HBM ESD performance
of up to 8 kV
◆ Reverse-voltage protection at supply pin
◆ Operating with static and dynamic magnetic fields up to 12 kHz with low output
jitter. Customized versions are possible
up to 93 kHz.
◆ AEC-Q100 qualification
◆ ASIL ready device (SPFM 60%)
◆ Additional functional safety features e.g.:
– Power on self-test (signal path test
and wire-break detection)
– Monitoring of bias, undervoltage, and
current level
– Overtemperature protection
– Output current limitation
– Defined fail safe state
◆ Wide junction temperature range from 
40 °C to 170 °C, specially designed for
operation in harsh environments
◆ High robustness of magnetic characteristics against mechanical stress
◆ Broad portfolio of temperature-compensated constant switching points

System Architecture
HAL 15xy sensors are monolithic integrated
circuits which switch in response to magnetic 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 appropriate state.
The built-in hysteresis eliminates oscillation
and provides switching behavior of the output without toggling. Magnetic offset caused
by mechanical stress is compensated by
using the “switching offset compensation
technique”.
