The HAL 283x are members of the Micronas varioHAL® (HAL 28xy) family of programmable linear Hall-effect sensors. The sensors feature a digital SENT interface (Single Edge Nibble Transmission). This interface enables a fast and robust data transfer in harsh automotive environments. The implementation of the interface complies with the SAE J2716 SENT standard release 2010-01.
 
The HAL 2850 is a new member of the -Micronas varioHAL (HAL 28xy) family of programmable linear Hall-effect sensors. It features a digital PWM output with slew-rate control, that enables a fast and robust data transfer in harsh environments. The PWM signal can be directly decoded by any unit measuring a duty cycle of a rectangular signal (usually a timer/capture unit in a microcontroller).
