HAL 15xy
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.
With different switching-point versions, the
HAL 15xy switch family serves a broad vari-
ety of automotive and industrial applications
under harsh temperature conditions.
◆ Reverse-voltage protection at supply pin
◆ Operating with static and dynamic mag-
netic fields up to 12 kHz with low output
jitter. Customized versions are possible
up to 93 kHz.
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.
◆ AEC-Q100 qualification
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.
◆ 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
Features
All CMOS wafer processing is done in
Micronas’ facilities in Freiburg (Germany) to
ensure best quality control and highest flex-
ibility.
◆ Sampling and output refresh time of 2 s
◆ 3-wire version with a short-circuit pro-
tected open-drain output
◆ 2-wire version with current output
◆ Wide junction temperature range from
40 °C to 170 °C, specially designed for
operation in harsh environments
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.

◆ Wide supply voltage operation from
◆ High robustness of magnetic character-
2.7 V to 24 V
istics against mechanical stress
◆ Overvoltage protection capability
◆ Broad portfolio of temperature-compen-
up to 40 V
sated constant switching points
◆ Available in the small SOT23 and
TO92UA package
◆ High HBM ESD performance
of up to 8 kV
