The Micronas HAL15XY Family At-A-Glance

Jan 18, 2017
 

HAL15yx


The Micronas HAL15XY is a multipurpose device to address all automotive applications. It fulfills the latest quality and functional safety standards as it is AEC-Q100 qualified and ISO 26262 compliant. The HAL15XY is the successor to the popular HAL5xy sensor which has been the standard for more than 19yrs in quality and reliability.  

HAL 15xy VS HAL 5xy

Hal 15xy edges over hal5xy in the following ways

-          Lower supply current

-          Can operate with higher dynamic magnetic fields + lowest jitter

-          Wider supply voltage range

-          Smallest state off art SOT-23JEDEC package

-          Additional self-protection functionality

-          ASIL A ready device 

-          AEC-Q100 qualification

Table describes the replacement matrix of the current Hall switch family HAL 5xy and the new Hall switch family HAL 15xy.

 

HAL 15xy is an optimal product solution for the following cases (Applications)

Position detection, as for

-          seat and pedal position

-          Gear shift lever

-          Seat belt presence detection  

Index counting, as for

-          Window lifter

 

Brushless DC motor commutation

Features The HAL 15xy family consists of different Hall switches produced in CMOS technology. All sensors include a temperature-compensated Hall plate with active offset compensation, a comparator, and an output stage. The family consists of 3-wire and 2-wire devices, the corresponding output stage being an open-drain output transistor and a current source respectively.
