RJM1013 / RJM1023 · Automotive-grade Vertical / Planar Hall Latch
3.3 V–24 V wide supply, 40 V load-dump and reverse-polarity protection, symmetric switching points producing a near-50% duty square wave — an ideal choice for motor commutation.
RJM1013 (planar Hall) and RJM1023 (vertical Hall) are Hall latches for automotive motor commutation and position sensing. The core control loop of a motor drive is sense–compute–drive, and the Hall sensor supplies the MCU/SoC with accurate rotor position — the prerequisite for commutation and closed-loop control.
The two variants offer vertical and planar sensing directions plus several sensitivity options, giving mechanical designers more freedom to optimize the magnetic circuit layout.
