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,

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 flex-

ibility.

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.
